Do varifocals damage your eyes?

Crystal clear eyeglasses

The trend is to make everything bright and clear. Frame shapes can be small and round or thick. Some have subtle colors like blue or gray, which makes the glasses look more jewel-like. Whichever you choose, a clear frame will help improve your style. Transparent, translucent frames have gone from being a bold fashion statement to a common, versatile option in the last few years, and now eyewear has more options than ever before. These frames vary from heavy traveler style to a more elegant corner frame to balance out your facial features. No matter what color or hue you choose, these clear frames show off your personality.

Gold round frame eyeglasses

Round metal frames have become a hot trend in the last two years, and the pop culture of metal glasses has become unstoppable. A round frame divides a big frame and a small frame, and a small round frame is more delicate. But the requirement for facial features is very high, and the big round frame is more lively and lovely.

But for glasses, in addition, to become fashion accessories, it is very important that they should be commensurate with their temperament, personality. Small round frames are more suitable for small faces and are more delicate, while larger faces will look larger and rounder.


Color process of Contact lenses

Pigment printing process

It refers to the direct printing of pigments or patterns on the inside of the lens and then drying, which is the main production process of poor-quality chromatic contact lenses. Usually, small factories and small workshops use this method. The lens is being phased out because the pigment can easily seep out from the surface during wearing, causing discoloration and staining, and irritation to the eyes, which is a big risk.

Pigment build-in process

To be specific, the lens made by sandwich technology is a three-layer structure, the front and rear are colorless transparent layers, and the middle is a colored layer. After the processing of sandwich technology, the color layer is wrapped in the middle of the front and rear transparent layer, so that the pigment will not contact the eyes, which will not cause irritation and injury to the eyes. The downside of this process, however, is that the lenses are slightly thicker than normal contact lenses and are less oxygen-permeable, so they are not suitable for long-term wear.

The pressed film manufacturing process

This is a relatively new method of a similar sandwich process, and the color (pattern) is also made between the front and rear layers of the lens. But the color (pattern) is used to fill in the film process. During lens curing, the pigment seeps into the material instead of sticking to the surface. It feels as if the lens is covered in color within a single layer. This reduces the middle layer and makes the lens thinner, which naturally makes it more comfortable and permeable to oxygen.



Proper massage

Proper massage can not only relieve the fatigue of the skin that supports glasses but relax the eyes. Take time each day to gently massage the marked area of the nose pad for ten minutes. Try not to wear glasses all the time. You can switch between contact lenses and glasses. In this way, over time, the nasal plate marks will gradually disappear. Hot towels can be used to warm the skin, which is helpful to blood circulation to the skin and slowly eliminate indentation.

Choose cost-effective lenses.

People who have high degrees choose the lens with a high refractive index like 1.60. So that the child's nose will not be compressed, which is the concern of most parents. Children grow faster, and the glasses replacement cycle is short. Adults should choose better quality lenses when choosing lenses, because a pair of glasses can be used for years, even in the situation when the frames are badly distorted and the lenses turn yellow. Zeiss A series lenses are cost-effective, suitable for people who are short of money and want quality. Nikon lens quality is very good, the film, wear, and sharpness are excellent. The disadvantage is that it is expensive, and the price gradient is quite large. The price scope is a bit wide, with two different refractive indexes.
