Metal Hinge TR90 Blue Light Blocking Glasses Unisex Women Men Round Eyewear
The lower density of the TR90 material makes the frame lightweight, reducing the burden on the wearer's nose and ears.
It can withstand high temperature of 350 degrees for a short period of time, not easy to melt and burn, suitable for use in a variety of environments.
TR90 eyeglass frames have a lubricated surface and a low coefficient of friction, which reduces friction damage to the wearer's head.
TR90 frames can be perfectly combined with other metals in bright colors, providing more choices for fashionable people.
