What is the best way to protect my eyes from the sun?
Medical studies have increasingly tied chronic exposure to UV and almost UV rays of eye diseases such as cataracts and macular degeneration. The shadow does not provide adequate protection because the eyes still absorb UV radiation, especially near water, snow or highly reflective surfaces such as concrete or sand. The best way to protect your eyes is a high -quality pair of sunglasses that meet the recommended sun protection criteria.
Although the lenses are the most important feature, if the frames allow a significant amount of light to enter the eyes without filtering through the lenses first, a large part of the sun protection has been lost. The most effective frames are the wrapping style that blocks the light in the inlet on the sides. The wrapping also hugs the face and reduces the amount of light that can enter the top or cheekbones.
It is also important that the lenses offer maximum protection from the sun. This does not depend on how darkness are lenses, but rather on their nursing to filter outÉ wavelengths. Look for lenses that block 100% UV-A and UV-B rays. These are the same rays that cause sunbathing and skin cancer. Although the UV-C beams are often mentioned, the Earth's atmosphere blocks virtually all of them.
It is also important to look for lenses that filter the almost UV light. Studies suggest that excessive exposure almost UV light contributes to macular degeneration, as we age, which is a chronic disease that results in impaired visual clarity. Near UV is also called high energy visible (heV) light or "blue light". These rays are less destructive than UV-or or UV-B rays and may not be completely blocked, but this spectrum should be at least partially filtered to provide better sun protection.
The range almost UV falls between 400 and 515 nanometers (nm) in visible light. If glasses “block almost UV to 400 nm"With an indicator that they do not block most of this spectrum. On the contrary, if" block almost UV light on 515 nm ", they filter out the entire spectrum and eliminate blue.
yellow lenses completely remove the spectrum of blue light and filter all Neauvovas rays. This disrupts color perception and is harsh for many people. Amber lenses block part of this range and are less rough than yellow lenses and maintain the actual color. Melanin lenses are relatively new, based on their own form of built -in sun protection and filter a large part of the almost UV or blue spectrum light while maintaining the true color of the heV lenses.
High -quality sunglasses will have a brand or accompanying information revealing the amount of sun protection they provide. The sunglasses that lack this information probably do not provide maximum protection from the sun, because 100% UV blocking and filtering are valuable sales points.
Although sunglasses may not be expensive,High -quality glasses are an investment in the long -term health of your eyes. Sunglasses that provide good sun protection all the time, a good pair of sunglasses is an investment that is worth money. Your eyes deserve good protection from the sun.
