Understand the impact of frame selection on the lens
Frame size is an important consideration when using progressive lenses because some progressive lenses work better in frames of different sizes. Since progressive lenses allow you to see at all distances, it's important that the whole range of vision fits within the frame. Therefore, very short lenses and larger lenses are not suitable for progressive lenses.
Contact Lens Material - PHEMA material
It is the earliest material used in the production of contact lens hydrophilic material. The main advantage is water absorption, with a water content of about 38%. The material is soft, but its disadvantage is only partial oxygen permeability.
The spirit behind celluloid glasses
Because celluloid material is flammable, it cannot be mechanized and basically needs to be created by hand, which forms a unique set of handcraft modes of Japanese crafters. Today, there are only a few celluloid factories in Japan, and the unique manual process and production are relatively small. This makes celluloid handmade glasses even rarer and more valuable. Celluloid was originally a very common and cheap material, even with a certain degree of danger, but because of the unique craftsmanship of skilled craftsmen, its performance was brought to the extreme, so that celluloid glasses became unique and sought after by some people. The material of the frame is an important factor that determines the comfort of the glasses. While ensuring comfort, people hope that the glasses can have a decorative effect and play a role in clothing matching in different scenes.
What effect does a lens with the hard film have?
In order to improve the wear resistance of the lens, it is necessary to coat the surface of the lens with hard film. At present, silicon atoms are used to stiffen the membrane, that is, the stiffening solution containing organic matrix and inorganic superfine particles including silicon element is used to make the hard film have toughness and hardness at the same time. Because the common resin lens is far easier to wear than the glass lens, so the addition of hard film is mainly used for resin lens. It is usually applied to the front surface of the lens, and the anti-wear ability of the resin lens with the film will be enhanced a lot, and the light permeability will be strengthened.
Pure titanium has special current characteristics
Pure titanium can guide electron fluctuations to produce ions, causing the current to tend to ionize. The positive and negative ions can adjust the adverse effects of electromagnetic waves caused by the body's biological current disorder and have a great health care effect on the human body in order to avoid fatigue, muscle stiffness, soreness, and other symptoms or problems.
