Role of Light Exposure in Myopia Management

The current trend of increased adoption of digital technologies by younger generations suggests that the future is likely to be promising for light therapies such as those used at home or that are wearable. However, at present, the most cost-effective and effective way to control myopia’s growing prevalence is to encourage children to spend more time in natural outdoor environments.

Children today are engaging in fewer outdoor activities compared to their predecessors from several decades ago due to the advancement of digital technology and the need for higher education; this shift towards an indoor lifestyle has been correlated with an increase in the prevalence of myopia. Outdoor light exposure has been suggested to provide a protective effect against myopia development since the late 18th century, with multiple factors attributed to this effect, including high-intensity ambient light, spectral content, pupil miosis, relaxed accommodation, and increased high spatial frequency. Furthermore, hypotheses have been suggested that link light exposure, circadian rhythm, melatonin levels, and ocular growth to the protective effect of outdoor light.

Light Exposure and Eye Health

Recent research has mainly focused on the effects of light intensity and wavelength on ocular growth. Studies have shown that short-term exposure to moderate to high-intensity light can slow axial elongation in humans. Additionally, one hour of exposure to blue or violet light has been found to be protective against myopia. Low-level red-light exposure has also been seen to have a positive effect on myopia control in children. Furthermore, daily morning light therapy with a wearable device has been proposed as a non-invasive treatment for ocular growth control. However, further clinical trials and validation are needed before these treatments can be recommended.

Indoors versus Outdoors

The differences in light intensity and spectral content between outdoor and indoor locations are considerable. Outdoors, light intensity can range from as low as 11 lux to as high as 9000 lux, while indoors, light intensity typically ranges from <1000 lux. Additionally, the spectral content of ambient light varies across different outdoor and indoor locations.

Studies have conclusively demonstrated the value of outdoor time in delaying or preventing the onset of myopia. However, its effectiveness in slowing down the progression of myopia has been unclear. A recent review by Dhakal et al. (2022) reported that in children who are already myopic, outdoor light exposure does not seem to control myopia progression. Even so, spending time outdoors is beneficial for general health, and it has the additional effect of reducing near work. A recent laboratory experiment showed that when children are outside, performing near work in an outdoor environment can lead to an increase in axial length compared to a distant viewing task in an outdoor area. Therefore, it is recommended that children be encouraged to engage in activities/sports that require distant viewing while outside, instead of focusing on digital devices or near-work activities.

Guidelines for Outdoor Time

Despite the extensive research into outdoor light exposure and myopia, many questions remain highly contested. What are the factors that contribute to the protective effects of outdoor time? Is it the intensity or type of light, or something else? What is the most beneficial time of day to be outdoors, morning or evening? How will increased indoor illumination in classrooms impact the development of myopia?

It appears that the most effective and economical approach to managing myopia’s increasing prevalence is advocating for children to spend more time in outdoor environments. However, there are no definitive guidelines for this, so it would be beneficial to recommend specific locations (e.g. open playgrounds/parks), times (e.g. during the day), and duration (e.g. two hours per day) of outdoor activities. As digital technologies continue to advance and young people become more tech-savvy, at-home and wearable light therapies may become viable solutions in the future.

How to protect eyes from harmful blue light and digital eye strain

In today’s digital age, our eyes are exposed to more blue light than ever before. Blue light is emitted from digital screens, such as smartphones, tablets, and computers, and can cause digital eye strain, fatigue, and other problems. Fortunately, there are steps you can take to protect your eyes from harmful blue light and digital eye strain. 

Reduce screen time. One of the best ways to protect your eyes from blue light is to reduce your screen time. This means limiting the amount of time you spend in front of a digital screen. It’s also a good idea to take breaks from screens every 20 minutes or so. 

Adjust brightness and contrast Another way to protect your eyes from blue light is to adjust the brightness and contrast of your digital screens. Make sure that the brightness is set to a comfortable level for your eyes, and that the contrast is set to a level that is easy for you to read. 

Use proper lighting  Make sure there is adequate lighting in the room. If possible, use natural light. If not, try to adjust the lighting in the room to reduce glare from the monitor.

Artificial tears can be beneficial in protecting digital eye strain. Artificial tears help keep the eyes moist and can help reduce dryness, stinging, and itching that can occur when using digital screens. Artificial tears can also help flush out any debris or irritants that may be causing the strain. Additionally, using artificial tears may reduce the amount of blue light that is being absorbed by the eyes from LED screens.

Take regular breaks It is important to take regular breaks away from your computer screen. Give your eyes a break by looking away from the screen and focusing on something else. If possible, get up and move around or take a short walk.

Use blue-light-blocking glasses Blue-light-blocking glasses are designed to filter out the harmful blue light from digital screens. These glasses can help reduce digital eye strain and fatigue, as well as improve sleep quality. 

Adjust your viewing distance When using a digital device, make sure you’re sitting at least an arm’s length away from the screen. This will help reduce digital eye strain and fatigue. 

Adjust the monitor settings The first step to reducing digital eye strain is to adjust the monitor settings. Make sure the brightness and contrast settings are set to comfortable levels. The text should be crisp and clear, and the brightness should not be too high.

Use the 20-20-20 rule The 20-20-20 rule is a good way to reduce digital eye strain. This rule states that every 20 minutes, you should look away from your screen and focus on something at least 20 feet away for 20 seconds. 

By following these tips, you can help protect your eyes from harmful blue light and digital eye strain. Remember to take breaks from screens, adjust the brightness and contrast of your digital devices, use blue-light-blocking glasses, adjust your viewing distance, and use the 20-20-20 rule.

The role of nutrition in maintaining healthy eyesight

Nutrition plays a major role in maintaining healthy eyesight, as the eyes require certain nutrients to keep them functioning optimally.The eyes are one of the most delicate and important organs in the body. They provide us with the ability to see and interpret the world around us. Therefore, it is essential to ensure that our eyes are kept healthy and protected. 

Nutrition is important for all aspects of health, including vision. Eating a balanced diet and getting the right nutrients can help maintain healthy eyesight and reduce the risk of certain eye diseases. Nutrients such as omega-3 fatty acids, lutein, zeaxanthin, zinc, vitamins A, C and E, and other antioxidants are all important for healthy eyes.

Vitamin A is important for healthy eyesight because it helps to keep the cornea, the clear outer layer of the eye, healthy. Vitamin A also helps to maintain the mucous membrane, which is a protective layer between the eye and the environment. Vitamin A deficiency can lead to dry eyes and vision problems, so it is important to get enough of this vitamin. 

Vitamin C is also important for healthy eyesight. This vitamin helps to protect the eyes from damage from free radicals, which are molecules that can damage cells and organs. Vitamin C also helps to reduce the risk of cataracts, which is a common age-related eye problem. 

Vitamin E is also important for healthy eyes. This vitamin helps to reduce the risk of cataracts and macular degeneration, which is an age-related eye disease that can cause vision loss. Vitamin E also helps to protect the eyes from damage from ultraviolet (UV) radiation. 

B-complex vitamins are also important for healthy eyes. These vitamins help to keep the eyes healthy and functioning properly. The B-complex vitamins include vitamins B1, B6, and B12, and they are important for maintaining healthy eyesight.

Vitamins A, C, and E are also important for eye health. Vitamin A is found in carrots, sweet potatoes, cantaloupe, and dark leafy greens. Vitamin C can be found in citrus fruits, bell peppers, and broccoli. Vitamin E is found in nuts, seeds, and vegetable oils. These vitamins are known for their antioxidant properties, which help protect the eyes from damage caused by free radicals.

Omega-3 fatty acids are found in certain fish, such as salmon, tuna, and sardines, as well as in nuts and seeds. These fatty acids are important for eye health, as they are known to reduce the risk of age-related macular degeneration, a common cause of vision loss.

Lutein and zeaxanthin are two carotenoids found in leafy green vegetables, such as spinach and kale, as well as in eggs and certain fruits. These two carotenoids are important for maintaining healthy vision, as they are known to reduce the risk of macular degeneration and cataracts.

Zinc is another important nutrient for eye health. It is found in oysters, beef, chicken, beans, nuts, and whole grains. Zinc is important for the development and maintenance of the retina, which is the light-sensitive layer of tissue at the back of the eye.

Copper is an essential nutrient for eye health. It helps the body produce melanin, a pigment that helps protect the eyes from ultraviolet (UV) radiation. Copper also helps to maintain the integrity of the eye’s retina, and it can help to reduce the risk of age-related macular degeneration. Additionally, copper helps to keep the eye’s lens flexible, which helps reduce the risk of cataracts.

Riboflavin is another key nutrient for eye health. It helps to produce the energy needed for cells to function properly and helps to protect the eyes from UV radiation. Riboflavin also helps to maintain the health of the cornea and the lens, and it can help to reduce the risk of age-related macular degeneration.

In addition to these nutrients, it is also important to get enough fluids to keep the eyes hydrated and healthy. Water is the best choice, but other fluids such as fruit juices, herbal teas, and vegetable juices can also help.

Overall, nutrition plays a key role in maintaining healthy eyesight. Eating a balanced diet and getting the right nutrients can help keep the eyes functioning optimally and reduce the risk of certain eye diseases. Eating a variety of fruits, vegetables, and other nutrient-rich foods can help ensure that the eyes get the nutrition they need. Maintaining a healthy lifestyle is also important for eye health. This includes getting enough sleep, avoiding smoking, and wearing sunglasses outdoors to protect the eyes from the sun’s ultraviolet rays.

benefits and risk of contact lenses

The benefits and risk of contact lenses versus glasses

Personal choice is the most important factor in deciding whether to use glasses or contact lenses. The decision-making process is influenced by factors such as comfort, convenience, lifestyle, cost, and aesthetics. When it comes to eyesight, simplicity of use, and eye health, both glasses and contact lenses have advantages and disadvantages, and neither is inherently better than the other.

Benefits of contact lenses

  • Contact lenses adjust to the shape of your eye, they may give you a broader field of vision while also reducing visual distortions and blockages.
  • Contact lenses  do not need to worry about your glasses falling off and frequently getting broken.
  • Contact lenses never look out of place with what you’re wearing and are unaffected by weather. You can see clearly even in rain or cold weather since there is no precipitation or fog to obscure your eyesight.
  • Colored contact lenses enable you to experiment with various eye colours by changing the colour of your eyes.
  • Some contact lenses have the ability to restructure your cornea as you sleep. These orthokeratology lenses may temporarily correct myopia, enabling you to see well without contact lenses or glasses the following day.

Risk associated with contact lenses

  • Some individuals have difficulty placing contact lenses to their eyes, but experience and good technique may usually correct this.
  • Because contacts lenses reduce the amount of oxygen that enters your eye, they may raise your risk of dry eye syndrome.
  • If you spend a lot of time on the computer, contacts might also raise your chances of developing computer vision syndrome.
  • Proper care and cleaning of your contact lenses is essential for your eye health and helps you prevent from eye infections. Individuals who are unable to commit to the maintenance and replacement cycle of contact lenses may try daily disposable lenses.
  • If you sleep with your contact lenses on, your eyes will most likely be dry, gritty, red, and irritated when you wake up. If you regularly fall asleep while wearing your contact lenses, you may want to look into extended wear contact lenses, which are authorised for up to 30 days of continuous usage.

Benefits of contact glasses

  • Use of contact glasses lessen your chances of irritating them and acquiring eye infections.
  • Contact lenses can irritate sensitive eyes, whereas glasses do not.
  • In the longterm, glasses are usually less expensive than contact lenses. Glasses don’t need to be updated as often, and even if your prescription changes, you may be able to maintain your frames and only change your lenses.
  • Glasses are more effective than contact lenses in shielding your eyes from wind, dust, and debris.

Risk associated with using Contact glasses

  • Glasses might affect your peripheral vision since they are around 12mm away from your eyes. When they first obtain glasses or alter their prescription, many individuals notice hazy vision or difficulty concentrating on things.
  • Eyeglasses are affected by the elements more than contact lenses are. Precipitation or hazy lenses might hinder vision.
  • Some people believe that glasses make them seem unattractive or that they impede their facial features.
  • The glasses’ thick borders may seem unpleasant, and certain grades of lenses may make your eyes appear abnormally large or small.
  • Ill-fitting frames might put pressure on your nasal bridge or the region behind your ears, causing general discomfort or headaches.

Many people use both contact lenses and glasses, switching between them depending on the task at hand or the preferred aesthetic. If you do decide to use contact lenses full-time, make sure you have a backup set of current glasses. This guarantees that your eyesight will function normally if you have to stop using contact lenses due to an eye infection or discomfort, or if you just want to relax your eyes.

The importance of regular eye exams and how often you should have them

The purpose of an eye exam is not only to assess your vision. Aside from the quality of your vision, several factors are evaluated during a standard eye exam. These include eye pressure, alignment, and evaluation of the retina, optic nerve, and other vital ocular components.

Most diseases that have the potential to cause blindness do not manifest symptoms until the condition is advanced. When detected, it is always too late to be corrected. Furthermore, some illnesses such as diabetes, cancer, thyroid, and hypercholesterolemia present in various parts of the eye and may be diagnosed early during periodic check-ups.

Knowing what a healthy eye looks like enables for minute changes to be recognized and analyzed for injuries and disorders. Detecting and correcting the beginnings of vision-threatening conditions such as cataract, glaucoma, and other retinal abnormalities. Being diagnosed with other conditions, such as diabetes, cancer, or hypertension, and taking proactive steps to control them.

Importance of regular eye check-ups:

  • Regular eye exams are essential for maintaining visual function in both proximal and distant vision. It illustrates the modifications that must be made on a regular basis depending on the improvement or degradation of visual function. Correcting your eyesight increases the quality of your daily life.
  • Ophthalmologists also examine patients for eye problems such as nearsightedness and farsightedness. The most effective strategy to determine the risk of nearsightedness and farsightedness is to schedule frequent eye examinations. If diagnosed early, steps may be done to delay the development and lower the chance of developing major eye problems later in life.
  • More than 75% of instances of blindness are avoidable if detected early. Having your eyes evaluated may help prevent or reduce the damage caused by a wide range of eye disorders, since more than half of blindness is avoidable.
  • Astigmatism, for example, requires cylindrical power, which optometrists identify during eye exams.
  • Several eye symptoms and disorders, once formed, are very difficult to treat or, in later stages, irreversible. Hence a thorough examination of the lens retina and optic nerves is very important.
  • Glaucoma is characterized as the “silent killer of sight” since most cases have no obvious symptoms. People only become aware of it when they have suffered irreversible visual loss as a result of the progression of glaucoma. Controlling glaucoma and preventing further vision loss becomes quite tough at that point. As a result, frequent eye examinations aid in the early diagnosis of glaucoma risk factors and prevent the condition from causing vision loss.
  • Cataract causes the lens of the eyes to become opaque, resulting in hazy and cloudy vision. To restore normal vision, proper eye examination, prompt detection, and lens replacement surgery are necessary.
  • A comprehensive eye exam may also detect age-related macular degeneration, which can lead to vision loss.
  • Regular eye examinations may reveal a variety of serious health problems. Eye specialists can assess the health and condition of blood vessels in the retina, which are a predictor of blood vessel health throughout the body. Diabetes, hypertension, and hypercholesterolaemia may all be diagnosed by changes in the appearance of the retinal blood supply and blood vessels. Annual checkups are especially important for those who have diabetes or are at risk of developing diabetes. Diabetes is one of the biggest causes of blindness in people. Diabetic eye disease has no obvious signs in the early stages. As a result, only a full eye exam can identify disease symptoms and allow doctors to initiate therapy to avoid vision loss.
  • Thyroid abnormalities are indicated by bulging or projecting eyes in Graves disease. Eye irritation may be a sign of an autoimmune disease like lupus. Unusual eye structure can be a sign of eye cancer ( ocular melanoma). Droopy eyelids and irregularly shaped pupils might indicate a neck tumor or an aneurism.

How often should an eye exam be performed?

The frequency of regular eye exams varies with age and the increasing risk of various health issues affecting vision and existing eye problems.

  • A child’s first eye examination is performed around the sixth month to ensure visual ability and to discover anomalies such as strabismus, lazy eyes, ptosis or drooping eyelid, cataract, and blocked tear ducts. These disorders, if not addressed promptly, may result in impaired eyesight or visual loss.
  • When poor vision and other visual disorders make it difficult for a child to read what is written in books or on the board, the next eye exam is advised right before beginning school.
  • Unless otherwise advised, an eye exam every 2-4 years between the ages of 20 and 39 is adequate to keep good eye health.
  • Eyesight abnormalities and disorders such as diabetes and hypertension, which may damage vision, are more likely to occur between the ages of 40 and 64. So, at the absolute least, schedule a check-up every two years.
  • A routine eye examination is required at the age of 65, and then once a year afterwards. Due to inadequate and poor-quality tear production and diabetic retinopathy, older persons are at a greater risk of vision loss and other disorders such as cataracts, age-related macular degeneration, glaucoma, and dry eye syndrome.

It is important to get regular eye exams to monitor the health of your eyes. Regardless of how keen your eyesight is, scheduling regular eye exams is an essential way to protect overall health and wellness.
