With the awareness of UV rays, more and more people pay attention to sun protection. However, most people do not know eyes are the organs that are still exposed to UV rays all year round. So, how much do you know about the dangers of UV rays to your eyes?
UV rays are divided into long waves and short waves. Both of them will damage our eyes.
Long-term exposure to short-wave UV light can damage the cornea and conjunctiva, like snow blindness. It is caused by the UV rays reflected in snow and ice. The eyes will suffer pain, photophobia, tearing, and even inflammation of the conjunctiva and cornea.
The lens will be damaged when the eyes are continuously exposed to long-wave UV radiation. For instance, a cataract is a condition in which the lens becomes cloudy. Aging is the primary cause of the disease, but excessive exposure to UV also increases the chance of developing cataracts. Symptoms include blurred vision, double vision, night blindness, photophobia, rainbow vision, and yellow or brown tint. Surgical replacement of the cloudy lens with an intraocular lens is the only treatment option.
If people stay outdoors for a long time, especially those who have to be under strong sunlight, they are prone to neoplastic tissue called pterygium, which is on the bulbar conjunctiva and cornea of the palpebral fissure. Farmers, skiers, fishermen, and surfers are most likely to suffer from the disease. So it is also known as surfers' eyes. It will affect the structure and blinking activity of the eyes. In addition, there will be repeated discomfort symptoms such as dryness, congestion, tearing, tingling, and burning sensation in the eyes, resulting in compliance astigmatism and affecting visual function. If the pterygium infiltration reaches the deep stromal layer and forms scars, it is hard to recover the best visual acuity after surgery and even causes blindness.
When the lens absorbs UV radiation, it may develop into eye cancer in rare cases.
The eyes are meaningful to everyone. To prevent or reduce the damage of UV rays to the eyes, we should avoid exposing our eyes to the sun for too long in daily life. Sun hats and sunglasses are vital pieces of equipment to protect our eyes from UV rays. Eyekeeper provides various sunglasses, such as clip-on sunglasses, sunshine readers, and bifocal sunglasses, which meet your different needs.
