Memory Titanium Flexible Full flex

These glasses have a titanium alloy (non-pure titanium) fully curved glasses frame and have acetate coating at the end. With aviation style, the latest fashion design is used, they are not heavy in weight. The frame is not heavy and flexible. It just needs a little tweaking. They are not heavy at all. Wearing them for hours doesn't cause stress headaches. The glasses can be adapted to informal moments like weekend brunches, or significant occasions, for example, at high-level business meetings. It's made of impressively flexible titanium, and you can twist the temple in each way you want.


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.



Choose high-quality lenses.

As resin lens technology becomes more and more mature now, resin lens has gradually become popular, so the use of resin lens is the trend. Now resin coated lenses are very popular now. There are anti-reflection films and hard films (anti-wear films) anti-UV films. Anti-reflection film can improve the transmittance of light, making people see more clearly, at the same time, because it can reduce the reflection, the lens is more beautiful in appearance. Hard coating films can effectively protect the lens surface from wear and tear and can resist the damage of hard objects, to prolong the life of the lens. UV-resistant films block the harmful ultraviolet rays of sunlight. For example, the UV400 lens is good for engineers who work outdoors for a long time.


Refractive index of spectacle lens

It is generally believed that the higher the refractive index, the better the spectacle lens. Such spectacle lenses are relatively thin, and of course, the price is a bit expensive. When the refractive index increases, the direction of the light entering the lens will change greatly, the focus will move to the lens, the focal length will be smaller, and the diopter will become larger. In order to keep the diopter unchanged, it is necessary to reduce the curvature of the lens, that is, to reduce the curvature of the mirror surface, so that the thickness of the lens can be reduced. This is why the larger the refractive index, the thinner the lens is. Under the same premise of other things, the larger the refractive index, the thinner the lens, the lighter and more beautiful the lens, and the higher the price, but the larger the refractive index is not the better.



What kind of lens is a progressive lens?

Progressive lenses are optical lenses designed for simultaneous correction of far, medium (for computer use), and near (for reading). They are Progressive Additional Lenses (PAL). The so-called progressive, The so-called progressive, is the use of polishing technology to achieve a gradual transition between the two focal lengths. The advantage of this design is that the wearer can see far and near objects alternately without taking off the glasses.


How to Tighten Glasses by Yourself

After your glasses being used for a while, they will become loosen. In this situation, you may want to ask for a professional optical person to adjust or tighten it. It would be a way but with some inconvenience. So, you can also choose to tighten glasses by yourself.

Why the glasses will become loose? It can be caused by various reasons. Most people wear and remove their glasses several times every day. The back and forth movements of the glasses’ arms will increase the possibility that they will become loose.

If the glasses become loose, you can choose to tighten them by adjusting the temple arms. Most eyeglasses have a screw located at the temple hinge on both sides. To tighten glasses by yourself, you can choose to tighten this screw to make your glasses more comfortable or prevent them from slipping down your nose again. You had better check these screws periodically so you can tighten them before they fall out.

Types of Progressive Lenses

At the same time, there are different types of progressive lenses and they are standard PALs, short corridor PALs, computer PALs, and Reading PALs.

Standard PALs must fit your vision needs. They can be added to frames of your choice, but you need to ensure that the frames are the right width and height proportions to grant enough space for the gradient changes in the lens.

Short corridor PALs are made to fit into smaller frames so as to suit a wider range of eyewear styles.

Computer PALs are designed for computer users and other occupations that require strong intermediate and distance vision.

Reading PALs are designed for those who enjoy reading and they can opt for a pair of lenses with a larger close vision zone.
