The damage caused by UV-A rays is cumulative and permanent, and can affect the cornea, the crystalline lens, the iris, the retina and the related conjunctival and epithelial tissues.
The NOuv technology lens completely eliminates UV rays up to 400 nm.
The potential harmful effects of UV rays are:
Ocular dryness and oxidative reactions to the conjunctiva
Yellowing and loss of transparency of the lens
Damage to the corn
Ultraviolet (UV) radiations are in the invisible region of the electromagnetic spectrum, between 100 nm and 400 nm, and they are divided into three bands (UVA, UVB and UVC) based on biological effects. The UV-C rays are absorbed at 100% by the Earth's electromagnetic field; the UV-B rays are absorbed at 95% by the terrestrial and ozone sphere electromagnetic field. UV-A rays affect the eye entirely.
We are specialized in optical lenses since 1950s in Italy. Now we have steady productions, research, sales, marketing, after sale care and so on.
We have past CE, FDA and some other certificate as for the medical device.
