Introduction
Tanning can be done using natural sunlight or artificial tanning beds, which may enhance the skin's appearance. Due to exposure to ultraviolet light (UV), tanning causes significant risks to the eye's health. UV radiation can cause immediate or long-term damage to various eye structures, impairing vision. UV radiation during tanning can cause acute eye conditions, such as photokeratitis (corneal inflammation similar to sunburn causing pain, redness, and temporary vision loss). Prolonged exposure to UV light can cause chronic or serious eye conditions, such as cataracts and macular degeneration. These can lead to permanent vision loss and even blindness. Protecting the eyes from tanning can be done by simple measures, such as using protective goggles. The article discusses the effects of tanning on eye health and the protection of eyes from harmful UV radiation.
What Is Tanning?
Tanning is the darkening of the skin color due to exposure to UV radiation. This can occur from natural sunlight or artificial tanning beds. When the human skin gets exposed to UV radiation, melanin pigment is produced (pigment responsible for skin color). An increase in melanin pigment causes darker skin tone, also called skin tan. Excessive exposure to UV radiation causes premature skin aging, sunburn, or skin cancer.
How Does Tanning Affect Eye Health?
Tanning significantly impacts eye health due to exposure of the eyes to UV radiation. The process of how tanning affects eye health is described below:
-
Photokeratitis: Excessive exposure of the eyes to UV radiation can cause the development of the condition, also known as sunburn of the eye. In the case of skin sunburn, the skin is affected. However, in the case of photokeratitis, the cornea is affected. The affected person may experience pain, tearing, redness, blurred vision, headaches, sensitivity to light, and temporary vision loss.
-
Cataracts: An eye condition in which the eye lens becomes cloudy. Overexposure of eyes to UV rays can lead to the development of cataracts. It usually occurs in old age, but UV rays accelerate the condition due to increased oxidative stress in the eyes. The symptoms include blurred vision, poor night vision, faded colors, and halos around light.
-
Macular Degeneration: Prolonged exposure to UV radiation can lead to the development of age-related macular degeneration, which is the major cause of vision loss in adults. In this condition, damage to the central part of the retina, called the macula, causes vision loss. The macula is responsible for sharp vision. Symptoms include trouble recognizing faces, faded colors, and difficulty seeing in low light.
-
Pterygium: If an individual uses frequent indoor tanning beds or lamps, growth may form on the inner or outer edges of the conjunctiva. The affected person may experience pain, redness, itching, and a burning sensation.
-
Eyelid Skin Cancer: Exposure to UV rays may increase the risk of developing skin cancer on the eyelids, such as melanoma, basal cell carcinoma, and squamous cell carcinoma.
-
Conjunctival Disorders: UV radiation exposure can lead to various conjunctival disorders, such as inflammation and thickening of the conjunctiva.
Who Are the More Susceptible Individuals to Eye Damage From Tanning?
Certain individuals are more susceptible to eye damage due to tanning. This can be due to genetics, pre-existing health conditions, lifestyle habits, and environmental exposures. People who are at high risk are described below:
-
Light-Skinned People: Light-skinned people have less melanin pigment, which provides natural protection against UV radiation. However, they are more prone to sunburns and associated eye conditions, such as cataracts and photokeratitis.
-
People With Light-Colored Eyes: People with blue, green, or gray eyes have less pigment in the iris, which means they have less natural protection against UV light. These people are more likely to have eye damage and develop eye conditions such as macular degeneration.
-
Older Adults: Age-related changes in eyes make older people more susceptible to the cumulative effects of UV radiation. Older people are at high risk of developing cataracts and age-related macular degeneration.
-
Outdoor Workers: People who spend more time outdoors, such as farmers, fishermen, and construction workers, experience more UV exposure to the eyes. They are at increased risk of developing cataracts, photokeratitis, and pterygium.
-
Pre-Existing Eye Conditions: An individual with pre-existing eye conditions, such as retinal diseases or dry eye, may experience exacerbated eye symptoms on exposure to UV rays.
-
Geographic Location: Due to less atmospheric filtration, people living at high altitudes near the equator are exposed to stronger UV radiation. They are at high risk of getting photokeratitis and pterygium.
How to Protect the Eyes From Tanning?
Protecting the eyes from the harmful effects of tanning is crucial to prevent damage from UV rays. The strategies to protect the eyes for tanning are as follows:
-
Use Protective Goggles: Individuals should always wear protective goggles to block sunlight and protect the eyes from harmful UV radiation. Ensure that the goggles fit and do not allow UV light to enter the eyes from the sides.
-
Wear a Hat: An individual should wear a wide-brimmed hat that provides additional shade and reduces the amount of UV radiation reaching the eyes and face. An individual can also wear a hat and sunglasses together to reduce direct sunlight exposure.
-
Sunscreen Application: People should apply sunscreen around their eyes and eyelids. They should wear sunscreen that is safe for sensitive skin and should not irritate the eyes.
-
Stay Hydrated: People should drink plenty of water to keep their eyes hydrated, which is important for maintaining eye health.
-
Avoid Looking Directly at UV Sources: Never look directly at the sun, as this can cause severe eye damage. Be cautious around reflective surfaces, such as water, sand, or snow, as these can reflect UV rays and increase the risk of exposure.
-
Regular Eye Examination: People should visit the eye specialist for regular eye check-ups to catch any early signs of UV damage. If an individual experiences any symptoms causing eye discomfort or changes in vision after UV exposure, they should take medical advice promptly.
-
Contact Lenses: Some contact lenses offer UV protection. These should not always protect the eyes from UV radiation. People should always wear UV-blocking glasses over them.
Conclusion
Tanning causes risks to eye health due to exposure to UV radiation. Overexposure or prolonged exposure of the eye to UV radiation can cause severe eye diseases, such as cataracts, macular degeneration, pterygium, and eyelid skin cancer. People should adopt protective measures to reduce the risks. Wearing UV-protected sunglasses and sunscreen application can reduce UV exposure. In addition, regular eye examinations can help detect early signs of eye damage.
