We are all aware of the importance of protecting our skin from the sun during the summer, we know that the burns may be severe and even lead to very serious diseases like cancer. But we realize that taking care of our eyes from sun exposure is just as important?
Our eyes are exposed all day to sunlight and may suffer but we care just as important as diseases of the skin. That is why it is important to wear sunglasses with UV filter.
There are different types of lenses, there are some that block ultraviolet light, other filter blue light, and other infrared.
The ability of a lens to protect against UV rays is given by the chemicals that are added to the lens material in its manufacture. Such substances which absorb UV rays.
There are different types of lenses:
* Blockers: absorb up to 99% of UV rays
* Blocking of infrared radiation, absorb up to 90% of infrared rays from the sun.
* Blocking the blue band: they are yellow lenses. It is not proven, but supposedly improve the definition of objects that are far away. That is why they use a lot of skiers and riders.
* Mirrored lenses: they do not absorb light but reflect it.
The people who most need care for your eyes from the sun are: those who have undergone surgery for cataracts. Those exposed to the flashes, such as welders. Those living in areas of high altitude. Those who suffer disorders of the conjunctiva, or muscle degeneration. And those who are exposed to sun lamps or Solariums for long.
Caring for our skin to sun exposure is essential, but our eyes too.
