What is the best lens material?

Crown glass was first used to make lenses. The glass melt was blown into a crown, or hollow sphere, and then reheated in the center of a rapidly rotating plate, which was then unrolled and flattened by centrifugal force. Flat and thin edges are cut into suitable shapes to make window panes. The circular bulge in the middle is the prototype of the lens. The glass material used to make lenses was originally colorless transparent glass with a refractive index of 1.523. Other substances were added to the lens to improve its ability to absorb ultraviolet light.

Why do people like wearing rimless glasses?

Rimless glasses are not heavy in weight, so they are suitable for all skin types. Even if you have oily skin, because the glasses themselves are not heavy in weight, they are not easy to slip off. Since rimless glasses have no frames and are made of memory titanium alloy, they are not heavy, which greatly alleviates the pressure on the bridge of the nose and eyes and makes them more comfortable to wear. And because there are no frames, the wearer has a wider field of view.


The hazards of rusty spectacle frames

The most common allergenic metal is nickel. Once allergy occurs, it can cause contact dermatitides such as redness, swelling, itching, and yellow water on the surrounding skin. Many alloy products in daily life contain nickel, such as coins, various alloy products, electroplated objects, spectacle frames, metal watchbands, belt buckles, artificial jewelry, underwear buckles, etc. Their direct contact with the skin will cause allergies to sensitive people. Therefore, the temples and nose pads are the parts that contact the skin with a larger area. In particular, the outer surface of the metal frame and the metal contain a large amount of nickel, which can cause rust spots and skin corrosion, and allergies through contact with the skin and the erosion of sweat.



Pair clear glasses with natural makeup.

Clear glasses and light makeup can make the focus of others in the glasses, so it will not appear abrupt. With a plain color coat, there is no sense of violation, and it is playful. A frame without lenses can be an accessory to give you a different feel.
