Why We Should Choose 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, 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 that 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.
What Is Polarizing Lens?
Glare-resistant and shatter-resistant lenses protecting
Polarized sunglasses are used to reduce glare from smooth surfaces such as water, snow, or glass. Glare distorts the true color of objects and makes them harder to distinguish.
Sunlight can be absorbed or reflected in several different directions. Sunlight that is bouncing off horizontal surfaces such as water, land, or the hood of a car is usually reflected back in a similar horizontal direction. This reflection produces an agitating source of glare that cannot only create visual discomfort but can also cause a potentially blinding glare. Glare has the potential to create a very dangerous situation, especially while driving.
Polarized lenses contain a laminated filter ( multiple coatings, have good flexibility) that allows only vertically oriented light to pass through. This blocks the horizontally oriented light so that glare is almost eliminated. (Do not intentionally damage the lens with heavy objects)
Advantages of polarized lenses
- Improves visual comfort
- Improves contrast and visual clarity
- Reduces eye strain
- Clearer vision, especially in bright light
- Reduces reflections and eliminates glare
Disadvantages of polarized lenses
- Polarized lenses aren’t good for …
- Looking at LCD screens
- Low-light situations and driving at night
- People who are sensitive to light changes
Whether it’s psychological or neurological, just as someone wearing contact lenses can produce 3D vertigo. Some people’s eyes may be sensitive to signals in a different way than the rest of us. In this case, tinted lenses may be the best choice.
Others require people to be able to read certain numbers on a LIQUID crystal display. Polarized lenses can sometimes interfere with the visibility of numbers and should be avoided.
