📝 Podcast Summary
Tips and insights for maintaining and improving vision health
Dr. Jeffrey Goldberg, an expert in vision, shares insights in a podcast about maintaining and improving vision health through behavioral tools, exercises, and surgeries. He discusses the benefits and drawbacks of corrective lenses, sunlight, and age-related considerations for LASIK surgery. Moreover, he explains ways to clean and use contact lenses, remedies for dry eye, and scientific approaches for nutritional supplementation. Dr. Goldberg also offers insights for newborn babies to maintain eye health. The podcast provides highly relevant and modern information to enhance vision quality and mitigate vision loss for potential diseases like retinitis pigmentosa, glaucoma, and macular degeneration. Furthermore, Dr. Goldberg's knowledge on curing blindness provides significant hope for people suffering from visual impairments.
The Importance of Regular Eye Exams for Children
Regular eye exams for babies and children are important to detect visual problems such as amblyopia and misalignment of the eyes early on. The first eye exam for babies involves checking the red reflex and parents should be aware of signs like lack of eye contact, nystagmus, and poor vision in one eye. Most kids get screened for amblyopia in elementary schools. Misalignment issues should be corrected as early as possible to prevent the brain from permanently losing the ability to develop strong connections from the data coming in from one of the two eyes.
How Retraining the Weaker Eye Can Improve Eyesight and Prevent Long-Term Damage
Retraining the weaker eye and realigning the muscles can help improve eyesight even in later childhood or early teen years and potentially reopen critical period plasticity. However, if misalignment or amblyopia is left uncorrected for years, it can lead to permanent damage and affect depth perception. It is important to maintain a balance of information coming into both eyes, even for short periods of time, and seek corrective measures such as patching the weaker eye to prevent long-term damage. Intermittent eye misalignment or amblyopia that goes unnoticed can accumulate over time and lead to vision problems, highlighting the importance of regular eye exams.
Outdoor Time May Help Prevent Myopia in Children
Spending time outdoors may reduce the risk of myopia or nearsightedness in children. Studies have shown that spending too much time doing near work such as reading or looking at screens may increase the risk of myopia. However, recent studies suggest that outdoor lighting plays a vital role in reducing the risk of developing myopia. Less exposure to full-spectrum lighting in typical indoor environments may also contribute to Myopia. Encouraging kids to spend time outdoors in sunlight can significantly reduce the progression of myopia in children. Parents can allow kids to use technology but ensure they spend considerable time outdoors as well.
The Importance of Outdoor Activities, Light Exposure, and Exercise for Eye Health.
Spending time outdoors can have potential benefits on eye health, but the optimum duration for such activities is still not well defined. Randomized controlled trials with control groups can help answer this question. Full-spectrum light can help set the circadian rhythm and is beneficial regardless of age, but it is not strongly linked to improving nearsightedness in older adults. Exercise has positive health benefits for the eyes and the rest of the body. While it is important to avoid extreme brightness, minimizing exposure to toxins, acids, and solvents can also aid in maintaining better eye health.
Importance of Eye Safety and Cleanliness
Eye safety and protection must be emphasized more as our eyes are delicate structures subject to degenerative disease and injury. People working in certain industries and even those doing gardening are at risk of eye trauma. Eye cleanliness is also important, but regular eye washing is not necessary as tears contain enzymes that break down bacteria. However, eyelashes and eyelids can accumulate dead skin, leading to inflammation that requires eye scrubs or using mild shampoo. Rubbing the eyes may not be harmful, but getting gunk in the eyes can cause temporary loss of vision, which is frightening as vision is crucial. More education around eye protection and proper eye cleanliness can prevent unnecessary eye injuries.
Eye Care Tips and Roles of Optometrists vs Ophthalmologists
Regular, occasional, gentle eye rubbing is fine as long as it is done without scrunching the eyes too tight and abrasive rubbing. Sterile saline solution is ideal for an eyewash, while preserved and non-preserved artificial teardrops are safe to use in the eye. Optometrists and ophthalmologists have overlapping roles in eye care provision, with optometrists focusing on primary care screening and early disease management and ophthalmologists having surgical training and managing more advanced diseases. Both can diagnose and prescribe appropriate treatments for eye diseases. It is recommended to get regular eye exams, even without blurry vision or difficulty seeing, and optometrists are easier to access but ophthalmologists are needed for eye surgeries.
The Importance of Eye Care for Maintaining Good Eye Health
Access to regular eye care is crucial to maintaining good eye health. While it may not be necessary to visit a specialist if you're in your teens, twenties, or thirties without any eye complaints, it is recommended to get screened for potential eye diseases like glaucoma. This screening could include a puff test to check eye pressure or an allotment test to check for eye rigidity. Additionally, presbyopia, or aging of the eye lens, may occur around age 40 and lead to the need for reading glasses even if distance vision is fine. It's important to get a comprehensive eye exam, including checking the surface of the eyes and the eyelids and lashes.
The Benefits and Risks of Using Reading Glasses
Using reading glasses can help relax our eye muscles and provide clearer vision for close-up tasks like reading a book or using a phone. As we age, the ability of our eye muscles to shape the lens gets weaker, which increases our dependence on reading glasses. While some studies suggest that using reading glasses may accelerate this dependence, the psychological addiction to good vision remains undeniable. Therefore, it's essential to take care of our eyes by exposing them to sunlight before using gadgets, practicing proper eye hygiene, and seeking regular eye checkups to detect vision problems early. It's best to consult an eye doctor before using any reading glasses or other vision aids.
Maintaining Optimal Vision with Glasses
As people age, they may need to use reading glasses or prescription glasses to maintain their optimal vision without straining their eyes. It is recommended to visit an optometrist or ophthalmologist for standard screening exams, and to use the appropriate lenses to avoid weakening the retina and brain by feeding it blurry information. While it is possible to exercise the lens and eye muscles by not using stronger readers or avoiding them, it is also important to give the retina and brain the sharpest visual signals available. One should enjoy their best vision all the time and not compromise their daily activities and enjoyment of life by avoiding using the recommended prescription glasses, including readers, as needed.
Dealing with Latent Hyperopia: Issues and Solutions
Latent hyperopia can cause people to struggle with nighttime vision and may require glasses with proper prescription lenses. Bright light can compensate for blurry vision during the daytime but can increase fatigue as muscles become tired. The focusing power of the optical system of our eyes is tuned for being beyond infinity, and latent hyperopias are constantly using those muscles. Corrective lenses such as prism lenses can cause significant shifts in eye positions and relying on them may not be useful. People may indulge in far viewing and full spectrum light during the daytime instead of depending on corrective lenses.
Importance of Proper Eye Care for Children
Proper eye care is essential in our formative years, and the right time to start is when children are young. Optometrists specialize in identifying the best corrective lenses for children to reduce eye strain and headaches that come with eye muscle exhaustion. It is essential to exercise the eyes, especially when they have a natural tendency to turn in when reading. Near-far exercises like pencil pushups are useful in exercising the eye muscles without causing any harm. However, it is crucial to consult an expert for the most suitable approach as each case may require a unique intervention. Visit an Optometrist or Ophthalmologist to correct any vision issues and improve visual health.
Enhancing vision activity and achieving supra-normal vision through training.
Pencil pushups help in recovering from Concussion by enhancing Smooth Pursuit which is the ability to smoothly follow an object with our eyes. Doing these exercises is safe and can improve visual activity. The new Vision performance center at Stanford is focusing not just on rehabilitating sick eyes but also on enhancing normal vision to supra-normal vision. This includes studying athletes' vision characteristics that show faster visual reflexes, higher visual acuity, and the possibility of achieving supra-normal vision through training. A great example is a training program using special goggles that black out visual information fractionally to improve catching and passing a basketball. The program is new and has opened up opportunities to understand how training can push normal vision towards supra-normal levels.
The Science of Human Vision Enhancement
Advances in human performance are expanding beyond joints, muscles, and strength to include vision. Researchers are studying the differences between normal and Supranormal vision and developing ways to measure and train people to improve their vision. This has practical applications for athletes, drivers, and regular people. Legal blindness is defined as 2200 or worse, but there are people with worse vision driving, which is dangerous. The standard for perfect vision is 2020, but some people can have better than normal vision at 2015 or 2010. In healthy people, the degree of visual acuity is generally similar between the two eyes.
The Importance of Visual Stimulation for Newborns and Benefits of Contact Lenses for Adults.
Newborn babies have blurry vision for the first six to eight months, so parents should smile big and give visual stimulation. While some species of animals have naturally better vision, humans have high acuity vision in the center of their field of view and a lower resolution, but fast detection camera at the periphery. Contact lenses can decrease oxygen diffusion and change tear dynamics, but most people can tolerate them well. Contact lenses can correct higher order aberrations that Glasses cannot, leading to higher quality vision.
Maintaining Eye Health with Contact Lenses
Using daily disposable contact lenses and following the recommended use and cleaning is critical in avoiding bacterial infections or corneal scarring. As we age, contacts may become less tolerable, so it's important to monitor how your eyes are adjusting. While blue light blockers can be helpful in reducing melatonin suppression at night, it's important to get enough bright light during the day. UV light, which is next to blue light on the light spectrum, is not good for our eyes or skin, so it's important to use eyeglasses or contact lenses with UV-blocking features to avoid sun damage.
Protection from UV Light for Healthy Eyes and Skin
It is important to block UV light to protect the periocular environment around the eye and prevent accelerated formation of cataract. While blue blocking glasses may not be helpful, wearing wide brim hats or sunglasses can reduce direct and reflected UV light exposure. However, it may not make a huge difference in the health of your eyes whether you wear them dogmatically or not. Morning sunlight viewing for 10 minutes is recommended, as low solar angle sunlight is not likely to cause extensive UV damage to the eyes. Wide brim hats also help by keeping the sun off your face and preventing skin cancers caused by sunlight exposure on cheeks and nose.
Understanding Light Sensitivity and LASIK Eye Surgery
People with blue or light colored eyes are more likely to have sensitivity to light due to biological differences in the iris muscles that constrict and dilate in response to light. LASIK eye surgery can correct misshapen corneas and improve vision, but may cause dry eye problems in some patients. It is important to consult with an eye surgeon before considering LASIK, especially if you already have dry eye. LASIK is a convenient and cost-effective solution for many people who would benefit from not wearing prescription glasses over the course of a decade or two.
The Importance of LASIK Surgery and Treatment for Dry Eye
LASIK surgery can greatly improve the quality of life for people with severe glasses or contact lens prescriptions, but it is generally not recommended for children or young teenagers whose eyes are still changing. Dry eye is a common eye disease that affects millions of people as they age, and it is caused by a decrease in both the quantity and quality of the tears our eyes produce. The saltwater component of tears can be replaced with over-the-counter artificial tears, but the oil component is more difficult to replace. The development of a treatment that works for dry eye, particularly for those for whom standard drops are not effective, would greatly enhance quality of life for many people.
The Rise of Dry Eye: Causes, Available Treatments, and Future Solutions
Dry eye is a major issue and has become more prevalent due to increased screen time. When we blink less, we distribute Tears less effectively and squeeze out less including the oils effectively, which hold tears on the surface of our eye. As an industry, we haven't figured out how to effectively replace or treat oil glands, causing discomfort for patients. While over the counter artificial tears work for most, severe cases require next generation treatments including eyelid cleaning, reducing inflammation, and regenerating nerves. Blood Serum tears contain growth factors that could help people with severe dry eyes, and PRP is related to but not yet used for this purpose.
Preservative-free and Serum Tears for Severe Dry Eye Symptoms
Preservative-free artificial tears are recommended for people with severe dry eye symptoms who use eye drops frequently. These are more expensive but are less irritating to the ocular surface as they contain no preservatives. Serum tears, generated by diluting liquid part of one's blood with saltwater, are being studied for their usefulness in ocular surface conditions. The serum contains growth factors that can aid in tissue rejuvenation. However, it is not a standard care treatment in ophthalmology yet. When a new treatment is introduced, proper trials and studies should be carried out to ensure safety and effectiveness before it is widely used.
Importance of Regular Eye Check-ups to Prevent Vision Loss and Access to Care in Ophthalmology
Refractive error is the most common cause of vision loss and is fundamentally correctable. Cataract is the second cause of vision loss and is a reversible and easily treatable problem. Glaucoma is the most common optic neuropathy and can lead to irreversible vision loss. It is important to get eye check-ups regularly to detect these conditions early and prevent or slow down their progression. However, access to care is a major issue in many countries, making it difficult for people to receive the necessary treatments. Therefore, there is a need for more global ophthalmology programs to increase access to care and solve these problems on a larger scale.
The Importance of Regular Eye Exams for Detecting and Treating Eye Diseases
Regular eye exams are crucial in detecting eye diseases like glaucoma, age-related macular degeneration, and diabetic retinopathy. Glaucoma, the leading cause of irreversible blindness, can be treated by controlling eye pressure through medications, lasers or surgeries. The disease affects peripheral vision first, and early detection is essential to prevent vision loss. Age-related macular degeneration is a common disease that affects the retina and compromises its function. Wet macular degeneration is the more severe form, where new blood vessels grow and interfere with vision, but treatments like antibodies injections are available. The future is promising for slowing down macular degeneration, but access to healthcare and therapies for eye diseases vary in the world.
Types of Macular Degeneration and Diabetic Retinopathy
Successful trials of a treatment for dry form macular degeneration have shown 20-25% slowing of disease progression. However, patients are still likely to experience vision loss. Retinitis pigmentosa is an inherited form of macular degeneration, affecting the rods, cones, and cells in the back of the eye. Although less common than macular degeneration, it can be devastating, especially in children and babies. Diabetic retinopathy is a major complication of diabetes, causing damage to the retina. Type 1 diabetics usually present with sudden loss of ability to make insulin, while type 2 diabetics can have a mild or severe continuum of insulin resistance. Both types are at risk of diabetic retinopathy with similar symptoms involving leaky blood vessels and microvascular events in the retina. Early screening is crucial for prevention and treatment of these eye conditions.
Controlling diabetes and blood pressure is key to preventing diabetic retinopathy and glaucoma.
Controlling blood sugar and blood pressure through lifestyle changes, medication, and regular eye exams are important to prevent or reduce diabetic retinopathy and glaucoma. Additionally, early detection and treatment of these conditions are crucial in preserving vision. Lowering eye pressure, even if initially within the normal range, has been shown to slow the progression of glaucoma. Diabetic retinopathy can be treated with drugs that can be injected directly into the eye. However, the most effective way to prevent diabetic retinopathy is to control diabetes with good blood sugar management. A comprehensive screening exam with checks for eye pressure and optic nerve head is necessary to reliably detect and monitor glaucoma.
Glaucoma Treatment Options and Risk Factors
Glaucoma can be treated with eyedrops or laser therapy, but long-term laser treatment may have advantages over eyedrops, including fewer side effects and better patient compliance. However, even with these treatments, 10-20% of patients may lose functional vision and 5-15% may go blind. Aging, smoking, and alcohol consumption are all risk factors for glaucoma and macular degeneration, and patients should strive to reduce these behaviors to improve eye health. Eye care providers should reinforce these messages with patients and encourage compliance with prescribed medications, even if patients do not notice daily benefits. It's important to detect and treat glaucoma early to prevent vision loss and to monitor the health of the optic nerve.
Cannabis and Ocular Health: Maintaining a Good Eye Health
Maintaining a healthy lifestyle, including regular exercise, a nutritious diet, and avoiding smoking and vaping, is crucial for maintaining good ocular health, especially for those at risk for glaucoma. While Cannabis may help to lower eye pressure, smoking is not recommended due to its negative impact on lung health and dry eyes. Edible forms may be used responsibly in select cases to control eye pressure at night while sleeping. Additionally, companies are working towards developing eye-specific and long-acting drugs derived from Cannabis compounds, which can be highly effective in treating glaucoma while minimizing any adverse side effects.
Sleep and Light Therapy for Eye Health
Getting a good night's sleep is crucial for the total health of the whole human being, especially for patients with severe glaucoma. Although studies on the impact of sleeping on either side on the eyes have produced conflicting results, it is believed the time and duration of sleep spent on each eye may be similar. Red or near infrared light therapy can be neuroprotective, and some studies show that it may help offset some vision loss due to age-related macular degeneration. However, the right dose, brightness, and optimal wavelength for the therapy are still unclear, and red light exposure, if too bright, can damage the eyes.
Exploring Light Therapies for Eye Health and Dealing with Floaters and Eye Twitching
Research is exploring the potential of light therapies to maximize our eye health, both during development and as we age. The occurrence of floaters is caused by the shrinking and contraction of fibers and gels in the eye as we age. Although it is tempting to remove them surgically, floaters usually go away by themselves within a few months. Patients often stop noticing floaters if they intentionally ignore them in the beginning. Eye twitching is mostly due to a bad nerve ending in the eyelid muscles. This can be caused by several factors, including fatigue and aging.
Supplements for Eye Health and Macular Degeneration
There are supplements available in the market for improving or maintaining eye health, but it's worth noting that only a few are supported by extensive studies. One such study is the ARIDS, which recommended a combination of Vitamin C, Vitamin E, zinc, copper, and betacarotene to slow down the progression of dry Macular Degeneration in moderate to severe ranges. Another study called ARIDS 2 proved that a lower dose of zinc and carotinoids like lutein and xanthine also help in slowing down the disease. These supplements are not recommended for mild Macular Degeneration but can be beneficial for those in the moderate to severe category. It's crucial to keep an eye on calorie intake to avoid obesity and diabetes that indirectly affects eye health.
Vitamin B3 may slow down optic nerve degenerative diseases.
Taking high dose Vitamin B3 supplements may help slow down the progression of optic nerve degenerative diseases such as glaucoma. Limited but randomized controlled clinical trials have shown that it is safe and may improve retinal function in the short term. Large phase three clinical trials are currently ongoing, and more data is expected to be available in the next year or two. However, patients should be cautious about other supplements that claim to support eye and vision health. While some may have a plausible explanation for how they may help, there is often no good data to support it. Patients should not substitute proven prescribed treatments with unproven alternative therapies.
Imaging the Neural Retina: A New Diagnostic Tool for Neurodegenerative Diseases
Imaging of the neural retina may be a powerful diagnostic tool for predicting and tracking the progression of Alzheimer's and other forms of neurodegeneration. While ophthalmologists are able to see the degeneration of the retina and optic nerve, there is not yet the specificity to differentiate between different diseases. However, recent discoveries of novel structures in the retina of patients with Multiple Sclerosis may lead to a new generation of biomarkers for diagnosing and treating diseases. This is an exciting area for eye care and the rest of medicine, as precision health aims to intervene early and prevent diseases in the future.
