Why you should have UV400 sunglasses!
UV rays damage the retina
The three types of uv waves emitted by the sun are UVA, UVB and UVC, the most dangerous of which is absorbed by the atmosphere.
Exposure to the sun without any protection from the sun can damage not only your skin, but your eyes as well.
If unprotected eyes are exposed to the sun, a long and intensive irradiation can lead to inflammations of the conjunctiva and cornea.
In the worst case, the visual organ may be damaged in the long term and the lens may become cloudy (cataract).
UV 400 meaning
UV 400 is the category which blocks all light rays with wavelengths up to 400 nanometers. This covers all of UVA and UVB rays.
All sunglasses with UV400 will protect your eyes and filter out harmful rays. Don't think it's safe to be overcast or in the shade, because ultraviolet rays can penetrate clouds even if the sun is hiding behind them.
All of our PARZIN sunglasses have the function of UV400. We take UV400 as the basis of our fashion sunglasses to protect every fashionista who pursues fashion.

For this subset of individuals, it is possible that the photoreceptor cells at the back of their eyes pick up the vertical light signals differently than the rest of us. Under these circumstances, tinted lenses may be the best option.
There are also occupations that require a worker to be able to read certain digital numbers on a liquid crystal display. Polarized lens sometimes can interfere with the visibility of the numbers and should be avoided.
