What is the difference between coloring diameter and diameter?

Colored contact lenses can enlarge your eyes while correcting your vision and making them deeper, but if they exceed the fit, it will backfire. Recently, businesses have added the coloring diameter of this parameter in the publicity, what does this mean, and what is the difference between the diameter?

The diameter of the contact lens is the actual lens diameter, including the transparent edge and the coloring part, which is the diameter of the whole lens. In general, the common lens diameters are 14.0mm, 14.2mm and 14.5mm.

The color diameter generally refers to the diameter of the color part on the lens of the color contact lens. When measuring, it is usually necessary to flatten the lens first, and then measure the color diameter through special equipment. Under normal circumstances, the minimum diameter of the color is about 13.8mm, and the largest diameter is not more than the size of the diameter of the lens. Different color contact lenses can often be seen after wearing the eye.

In fact, the lens diameter has little effect on wearing, but the coloring diameter will affect the size of the pupil. The lens with a large coloring diameter seems to enlarge the pupil after wearing. However, because the ratio of white eyes and eyeballs is 1:2:1, more harmonious and good-looking, so it is recommended that we do not blindly pursue large diameter and large colored contact lenses. It can look strange if the eyes are small and you wear large diameter contact lenses.

For many people, contact lenses have become cosmetics and even daily necessities. Therefore, in view of the large impact of the effect of the coloring diameter on wearing, Xiaobian suggests that you carefully and carefully choose, do not confuse the coloring diameter and the actual diameter of the two parameters.
