Sunlight provides essential benefits for our overall well-being. Still, it is important to remember that prolonged exposure to sunlight, especially its harmful ultraviolet (UV) rays, can harm our eyes. The eyes are susceptible organs and overexposure to sunlight can lead to various eye conditions and vision problems. Some of the conditions that sunlight can bring when it damages your eyesight include the below information.
Photokeratitis, also known as “sunburn of the cornea,” occurs when the cornea, the clear front surface of the eye, becomes inflamed due to excessive exposure to UV rays. It can cause eye pain, redness, watering, and sensitivity to light. While photokeratitis is typically temporary and heals within a few days, repeated incidents can lead to long-term damage and an increased risk of other eye conditions.
2- Cataracts Formation
UV rays contribute to the development and progression of cataracts, which cause the eye’s lens to become cloudy, resulting in blurred vision. Therefore, long-term exposure to UV radiation increases the risk of cataracts, making it essential to protect your eyes from excessive sunlight throughout your life.
3- Macular Degeneration
UV rays can damage the macula, the central part of the retina responsible for clear vision. Over time, this damage can lead to a gradual loss of vision, making it difficult to read, recognize faces, or drive.
4- Conjunctival Disorders
The conjunctiva is the thin, clear tissue that covers the white part of the eye and lines the inside of the eyelids. Prolonged exposure to UV radiation can lead to various conjunctival disorders, including conjunctivitis (pink eye) and subconjunctival hemorrhage. These conditions cause redness, irritation, and inflammation of the eyes, affecting comfort and vision.
5- Pinguecula and Pterygium
Prolonged exposure to sunlight, particularly in environments with high levels of UV radiation, can also contribute to developing pinguecula and pterygium. Pinguecula is a yellowish bump that forms on the conjunctiva, whereas pterygium is a growth that extends onto the cornea. Both conditions can cause discomfort, redness, and a foreign body sensation. Moreover, the pterygium may severely affect vision if it grows over the central cornea.
6- Skin Cancer Around the Eyes
The skin around the eyes is delicate and highly susceptible to the harmful effects of UV radiation. Therefore, excessive UV radiation exposure can increase the risk of developing skin cancer. This can include squamous cell carcinoma, basal cell carcinoma, and melanoma in the surrounding area. Furthermore, skin cancers in the eye area can be challenging to treat and may affect the function and aesthetics of the eyes.
Protecting your eyes from the damaging effects of sunlight is crucial for maintaining good eye health and preserving your vision. The risks associated with UV radiation, such as cataracts, macular degeneration, photokeratitis, pinguecula, pterygium, and skin cancer, highlight the need for preventive measures.
Furthermore, remember to wear sunglasses that block UV rays and specialty glasses like solar eclipse glasses when needed to safeguard your eyesight, especially during peak sunlight hours. Additionally, consider using wide-brimmed hats and seeking shade whenever possible. By taking these proactive measures, you can reduce the risk of sun-related eye damage and safeguard your eyesight for years.
