What Happens When You Don’t Wear Sunglasses?

In 1981, Australia launched an event called "Slip Slop Slap". Seagull Sid encourages people to put on T-shirts, put on sunscreen, and put on a hat to minimize UV radiation exposure and reduce the risk of sunburn and skin cancer. In 2007, the slogan of the event became "Slip Slop Slap Seek Slide". The initiative now also includes finding shade and wearing UV protection sunglasses to further reduce peoples exposure to UV-related injuries. Let us look at the hazards of not wearing uv400 protective sunglasses.



Short-term effects without sunglasses


Short exposure of unprotected eyes to ultraviolet light usually does not produce any symptoms. However, long-term exposure to ultraviolet light or strong ultraviolet light (including the sun, welding arc) without eye protection can cause photokeratitis in the human eye. This condition can be understood as a sunburn of the cornea (cornea, a clear and transparent layer in front of the eye).


Ultraviolet rays can kill the outermost cells of the cornea. After the eyes are exposed to sunburn, severe pain will occur after about 6-12 hours. The treatment of photokeratitis includes oral analgesics and the use of ophthalmic antibiotic ointment to prevent the injured cornea from being infected while waiting for the regeneration of the corneal cells. The process of complete recovery takes 24 to 72 hours.



The long-term effects of not wearing sunglasses


Repeated exposure to ultraviolet radiation and lack of eye protection can cause permanent eye damage. Eye diseases caused by long-term ultraviolet radiation include the following:





The lens of the eye of a cataract patient may become cloudy. This can cause blurred vision and eventually blindness if left untreated. It is estimated that 20% of cataracts are caused or worsened by ultraviolet radiation. Wearing sunglasses is one of the most effective ways to prevent cataracts.





This is a benign hyperplasia of corneal and conjunctival tissue. The conjunctiva is a transparent membrane covering the sclera (white part of the eye) and generally does not cover the cornea. Although not carcinogenic, the appearance of pterygium can cause chronic irritation, redness, and inflammation. Long-term exposure of the eyes to ultraviolet light without protection is the main factor leading to the appearance of pterygium.



Macular degeneration


Macular degeneration is a degenerative disease that affects the middle part of the retina (responsible for central vision) (macular spot). Macular degeneration may cause severe visual impairment. The treatment of macular degeneration includes direct injection of drugs into the eye to limit the deterioration of the disease; but this method does not cure existing injuries.


Although the link between ultraviolet radiation and macular degeneration is not as obvious as that of cataract and pterygium, short-wave radiation and blue light (appearing in bright sunlight) can damage the retina. There is still a relationship between macular lesions and light exposure.Therefore, wearing sunglasses plays an important role in limiting the exposure of the retina to excessive light.





Although this situation is relatively rare, long-term UV exposure is associated with an increase in the incidence of several types of eye cancer. These types of eye cancers include: squamous cell carcinoma of conjunctiva, melanoma in the eye, and skin cancer in areas around the eyelids and around the eyes where people do not often apply sunscreen. Treatment of these cancers may sometimes require surgery to remove the entire eyeball.
