Men's clear glasses are a fashion item.

A clear glasses frame is not only for a schoolgirl. Clear and transparent design more feel cool and refreshing in scorching summer. At the same time, it will not cover the facial features too much, making the face more delicate and clean. Small pure and fresh picture frames tie in some of the clothes of literature and art naturally. Therefore, the scope of use of clear glasses is very limited, only suitable for fashionable men.


There are three processes for resin-changing lenses.

The incorporation method, known as bulk polymerization, is similar to the method of glass lens, that is, one or more photochromic dyes are directly incorporated into the polymer monomer of the substrate for bulk polymerization, and the lens formed after curing will change color. Discoloration dye is completely integrated into the resin lens substrate, so the lens made of color persistence is very good.

The uniformity of discoloration and the depth of color after discoloration are highly related to the thickness of the lens. Because the thickness of the lenses at all levels is different, there will be a color difference between the depth of discoloration and the uniformity, and the uneven phenomenon of high brightness is more obvious.

The film type is known as the coating method. It is the chromatic resin lens by coating or dipping in a layer of chromatic dye on the base of the resin lens. Because the coating covers the surface of the lens, the color uniformity is good. The coating, which is only about 0.05mm thick, does not provide enough molecules to make the lens dark enough, so the color is relatively less dark, and the discoloration lasts slightly longer.

Infiltration, known as the penetration method, is to use the principle of penetration, through the thermal diffusion method to make the color dye permeate the surface of the resin lens sheet material, with diffusion depth up to 0.15~0.20mm. The lens has a constant color change characteristic. There will be no inconsistency between the center and the surrounding color as the luminosity gets darker. The color-changing resin lens made by infiltration type has the benefits of uniform color-changing, small color difference, fast and thorough color-fading, which is the mainstream of color-changing technology at present.



The Pros of Progressive Lenses

In this section, we will show you the benefits of progressive lenses.

One of the major advantages of progressive lenses is that the design of progressive lenses blends the prescription. There is no image jump or visible line on the lens. This enhances your comfort with your lenses and can be safer when performing tasks such as driving.

With progressive lenses, you don’t have to switch other glasses frequently. Progressive lenses correct distance, intermediate, and reading vision within one lens. So, it can bring you great convenience.
