The reading glasses strengths range from +0.75 dioptre to +3.00 dioptre. Both lenses have the same power which is indicated by a permanent marking on the inside of the frame or with a removable sticker on the lens. So, you can find the reading glasses strengths of the glasses.

TR90 has features of wear resistance, good chemical resistance, solvent resistance, weather resistance, not burning, high-temperature resistance. Plastic steel does not contain any metal, but it is a kind of high-strength molecular material, lighter than TR90. They have a higher level in corrosion resistance and strength and other aspects. The frames made of good materials are more comfortable, durable, and textured in daily wear, and will not cause skin allergies.
