Toxic air pollution levels in Mumbai and the surrounding areas are on the rise, and if experts are to be believed, the air we are breathing is full of obnoxious gases and harmful pollutants. Some studies on the pollution have revealed that the air quality in Mumbai is as bad as smoking four cigarettes in a day.

Transport vehicles, heavy construction activities, and industries emitting toxic pollutants are the most common causes of this increase in air pollution. According to the government, pollution levels have reached an emergency level, posing a health concern.

People who work outdoors or play outdoors (especially children) are the most affected by pollution. Masks may offer partial protection against cardiovascular and respiratory diseases, but the eyes are still exposed to harmful chemicals.

How does smog affect your health?

The term “smog” refers to a dense air layer which forms near the ground when air pollution is high. It is common in cities with high traffic or near industries with high emissions. Light reacts with gases in the lower atmosphere (car fumes/industrial emissions) to form smog. Some people are more sensitive to its effects than others, such as those who suffer from lung or heart ailments. The first sign of health problems caused by smog is irritation in the nose, throat, lungs, and eyes. In some cases, it may also affect the respiratory system and breathing.

Extreme pollution in the form of smog can affect eyes, cause allergies and damage to the overall health of an individual. The poor quality of air contains harmful gases like carbon monoxide, nitrogen dioxide, and coarse dust particles, which have caused an increase in red and watery eyes and various eye allergies.

These are the most common eye conditions caused by air pollution/smog:

• Watery eyes
• Burning sensation or discomfort
• Sore eyes
• Redness
• Swelling
• Itching sensation
• Dry eyes: A condition characterized by Dryness, Gritty feeling, and foreign particles in the eye.
• Eye allergy: A condition characterized by itching, redness, discharge, swelling of the eyelids, blurring of vision, and an increased risk of infection.

To minimize the risk of infection, there are many steps that can be taken. Here are some of them:

1. A good rule of thumb would be to avoid exposure to harmful pollutants. When the pollution levels are such that there is a public health warning, please stay indoors, especially in the early hours of the morning when they are the highest. If you must step out and are exposed to the environment, wear protective eyeglasses to minimize your exposure to pollutants.
2. Avoid touching your eyes and wash your hands often
3. Stay hydrated to ensure adequate tear production. It becomes even more important when environmental factors such as smog increase the chances of having dry eyes and eye irritation. The best thing you can do is drink eight to ten glasses of water each day.
4. Eat a diet rich in omega-3 fatty acids, such as green leafy vegetables, carrots, spinach, almonds, walnuts, and berries.
5. When you are outside, wear sunglasses.
6. Be careful not to rub your eyes.
7. Use eye drops to lubricate your eyes; these are readily available over the counter. Nevertheless, it’s important to have your eyes examined before using any eye drops.
8. Avoid excessive use of screen devices, such as mobile phones and laptops. Take adequate rest to prevent eye fatigue, dry eyes, and computer vision syndrome.
9. A visit to your ophthalmologist is recommended if the irritation persists, as they will determine a possible course of treatment.

Special situations:

1. Avoid the Use of Contact Lenses: Never use contact lenses if you have redness or discomfort in your eye unless instructed by your eye care professional. When the particulate matter index is high, protective glasses may be useful over contact lenses. It is prudent to remove your contact lenses if you experience any discomfort while wearing them, use lubricating eye drops, and seek the attention of your ophthalmologist as soon as possible. It is important to check the lenses for scratches and to make sure they have been cleaned properly before wearing them again.
2. Avoid the use of Eye Makeup: If your eyes feel uncomfortable, avoid using eye makeup. It is common for kajal and mascara to aggravate eye allergies and cause infections as well. Choose a reputed, hypoallergenic brand to ensure your eyes won’t be adversely affected by the chemicals in the makeup. It is also wise to remove all eye makeup before you go to bed in order to mitigate the ill effects of the chemicals.

Conclusion

As a precautionary measure, we should avoid exposure to pollution during smoggy weather for our overall well-being and optimal vision care. Keep an eye on the air quality index and avoid visiting polluted areas. Keep your windows and doors closed during periods of high pollution, and don’t go outside as much as you can. If you are experiencing allergies or infections in your eyes, see an eye specialist near you right away and undergo a thorough eye examination.

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, the 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.

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.

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.
