When it comes to the damage that the sun may bring, most people may worry about their skin, but the sun’s ultraviolet rays can also threaten people’s eyes.

How do ultraviolet rays damage your eyes?

According to a 2014 study by the U.S. National Eye Institute, ultraviolet rays can damage the protein in the lens of the eye, which may increase the risk of cataracts and damage people’s eyesight in the long run.

In addition, UV damage may increase the risk of macular degeneration (one of the main causes of aging blindness). Cancerous eyes and photokeratitis are also related to exposure to the sun.(

The risk of eye damage caused by sunlight will be more magnified at a specific time and under a specific environment. Water, snow, and car windshields can all reflect light into the eyes. At the same time, the higher the altitude, the stronger the sunlight, and the risk of people's eye damage also increases.

Do cheap sunglasses have UV protection?

Wearing sunglasses can protect human eyes from all the above concerns. Although not every pair of glasses is the same, Taylor said that no matter how dark the glasses are or what color the lenses are, the most important thing is that sunglasses can isolate 99 to 0% of ultraviolet rays, UVA, and UVB.

The price of glasses is not necessarily important. Even cheap sunglasses can be effective to block ultraviolet rays. Just look for sunglasses with 'UV protection' stickers or labels.

Different lens sizes have different protective effects

However, the size of the lens will vary. In 2018, a study conducted by Swiss researchers found that large-scale sunglasses are more effective in blocking ultraviolet rays than sunglasses with smaller lenses. And UV-resistant goggles provide the most complete protection.
