DAIWA Polarized Glasses DO-8322H Photochromic Polarized Lens Overglasses Gray

Photochromic lenses that change color depending on the amount of UV rays!
Over-type that can be worn over glasses!

Lens
A lens function that changes color depending on the amount of UV rays.
The lens is darker during the day when the sunlight is dazzling, and the lens is thinner in shaded places,
so you can always maintain a comfortable field of vision and reduce the hassle of putting on and taking off polarized glasses.
It also has a polarizing function, so it effectively blocks out miscellaneous light such as reflections on the surface of water.

Frame
Over-glasses that can be worn over glasses.
The frame is made of lightweight material TR-90.
A material that has excellent elasticity to prevent deformation and breakage, and is difficult to distort.
In addition, it is a material that is soft against the skin, so it is used for baby bottles and medical catheters, so it is less likely to hurt the parts that touch it.
The ear hook part of the frame is made of a soft rubber material that is soft against the skin to prevent ear pain.
Also, because it has a core material, you can bend the shape with your fingers,
and adjust it to fit your head without it slipping.

Photochromic lens
Uses lenses that change color in response to UV rays.
Normally, the field of vision is good, and as the UV rays get stronger, the lens color gets darker,
adjusting the amount of light entering the eyes and reducing glare.
