1.59 pc Blue Cut Photochromic Gray HMC Optical lenses

Short Description:

We all know that lenses play a decisive role in a suitable pair of glasses, so when choosing lenses, we should make choices according to our work, life needs and working environment. For example, students, drivers, doctors, etc., such people have high visual requirements for color and distance.

Therefore, when choosing lenses, colorless and transparent lenses should be preferred.

Does the lens transmittance also have high or low?

Refers to the ratio of the total amount of light entering the eye through the lens to the total amount of light reaching the lens. The higher the ratio, the better the light transmission performance and the higher the definition.

In general, optical lenses with multi-layer anti-reflection film, colorless optical lenses and aspherical ultra-thin optical lenses have good light transmittance, up to 99%. In this way, the wearer can not only see more clearly, but also greatly improve the visual contrast and minimize visual fatigue.

Production Introduction

How to control the thickness and weight of the lens?

The thickness of the lens is related to the height of diopter, refractive index of the lens and the shape and size of the frame, so when choosing the thickness of the lens, you should refer to your myopia degree. If the degree is higher, choose high refractive index lens preferentially, so the lens thickness is relatively thin, can also greatly reduce the pressure on the bridge of the nose.

Furthermore is the weight of the lens, when it comes to the weight, certainly not related to the material of the lens, the lens material on the market is generally glass, resin and PC, glass lens is the heaviest, PC lens is the lightest, so in the choice, the thickness and weight of the lens should also be taken into account.
