<\/p>\nUV rays, acronym for “ultraviolet,” are a form of electromagnetic radiation with wavelengths shorter than visible light. They are divided into three categories: UVA (315-380 nm), UVB (280-315 nm), and UVC (100-280 nm), of which only the first two rays reach the Earth’s surface.<\/p>\n

What damage can UV rays cause to our body?<\/strong><\/p>\n <\/p>\n Exposure to UV rays can cause damage to the skin and eyes, such as sunburn, premature aging, wrinkles, dark spots, and, in extreme cases, skin cancer. It is therefore important to protect yourself properly from UV rays, for example, by using high-protection sun cream and sunglasses. How can we protect ourselves from UV rays<\/strong><\/p>\n <\/p>\n To protect the eyes from the damage of UV rays there are some things we can do:<\/p>\n <\/p>\n Wear sunglasses with UV protection lenses<\/strong> <\/p>\n Use sunglasses with side coverage<\/strong> <\/p>\n Choose good quality sunglasses<\/strong> <\/p>\n Use hats or visors<\/strong> <\/p>\n Avoid looking directly at the sun<\/strong> <\/p>\n It is important to protect yourself even on cloudy days<\/strong> For these reasons, it is always recommended
\nIn particular, the eyes are sensitive to ultraviolet rays, and the eye tissues mainly involved in their absorption are the cornea and lens.
\nExposure to UV rays is indicated as one of the major risk factors for various eye diseases, including:
\n\u2014 Pterygium: fibrovascular thickening of the conjunctiva
\n\u2014 Keratitis: severe inflammation of the cornea that causes pain and photosensitivity
\n\u2014 Cataracts: progressive opacification of the lens cells
\n\u2014 Skin cancer in the eyelid area<\/strong><\/p>\n

\nChoose sunglasses that block at least 99% of UVB rays and 95% of UVA rays. Gray lenses are often the best choice because they do not alter real colors.<\/p>\n
\nGlasses with side coverage block UV rays that can penetrate the lenses laterally. This type of glasses is particularly important if you work or practice outdoor sports.<\/p>\n
\nCheap sunglasses may be attractive, but they often do not offer adequate protection against UV rays. Investing in a pair of quality sunglasses with protective lenses is a smart choice for long-term eye protection.<\/p>\n
\nWearing a hat or visor can help reduce exposure to UV rays on the sides of the face and eyes.<\/p>\n
\nNever look directly at the sun, as exposure to UV rays can cause serious eye damage. If you need to look at the sun for some reason (such as during a solar eclipse), use special glasses designed for sun protection.<\/p>\n
\nEven when the sky is overcast, about 90% of UV rays can still enter our eyes. Therefore, it is always recommended to use lenses, both prescription and sunglasses, that provide UV protection.<\/p>\n
