Today I will talk about the importance of the sun in our eyes. Ultraviolet radiation can cause severe eye damage.

I

Excessive sun exposure can affect our eye health, triggering a series of illnesses or symptoms exacerbating existing conditions. These diseases include:

I

- Pterygium: it produces eye irritation, foreign body sensation and occasionally, corneal opacification. In this sense, we have found a relationship between the appearance of this disease and sun exposure, especially that received in the first five years of life.

I

- Cataracts that are the leading cause of reversible blindness worldwide. His early onset is associated with excessive sun exposure in the first decades of life. Hence the importance of using sunglasses during childhood.

I

- Macular degeneration: is the leading cause of irreversible blindness in people over 65 in the Western world. Behind this disease, among others genetic factors, smoking, and the effects of the sun. In this regard, it has been found that not only the ultraviolet radiation, but also the light of the blue region of the visible spectrum, can be harmful. Furthermore, this exposure is greater in early ages, because the lens is more transparent. Many studies have shown that the use of sunglasses during the first decades of life significantly reduces the incidence of this disease.

It is therefore very important to protect your eyes with sunglasses, which are essential for the protection they offer against UV rays.

I'll give you some advice when buying our sunglasses:

  • I
  • Pay special attention to children, the lens is almost transparent to 10 or 12 years, and his eyes absorb all radiation. Do not buy sunglasses toy or do not comply strictly with the regulations of the European Commission. For children polycarbonate lenses, more resistant to breakage recommended.

The use of sunglasses that do not adequately filter out UV rays can be more dangerous than not wearing sunglasses. Some poor quality glasses cause glare on the pupil, so even though you think you are protected with them on the sun is directly over your eyes. Therefore, we need to make much where we buy our glasses, because there are sites that sell very cheap sunglasses but did not make the main function of the same. Intense headaches may be due to an inadequate use of sun glasses.

The damage caused a inadequate glasses do not appear immediately, but after a few years and in most cases the lesions are irreversible
