What Are Anti-Glare Glasses?
Anti-glare glasses are made with lenses that have an anti-glare coating or anti-reflective coating. This is an extremely thin layer placed on the lens itself so as to remove any reflections you might see from the surface of the glasses. This improves your vision by reducing the amount of glare that reflects off of your lenses.
Disadvantages of Progressive Lenses
It is limited in applicable range. Progressive multi-focus lenses have no limit in strength and can be worn for myopia, presbyopia, or moderate astigmatism, but they are not suitable for everyone. Now there are more than two categories of asymptotic focus lenses, one is hard and the other is soft. A person who can understand and adapt to the temporary discomfort that progressive multi-focus lenses begin to produce can have a pair of glasses. If you have severe symptoms such as high blood pressure, dizziness, or have a misunderstanding on progressive multiple focal lenses, and you are unwilling to adapt to them, it will be difficult to try.
What are the benefits of the TR-90?
Impact resistance is more than 2 times of nylon material, in order to effectively prevent the damage to the eyes caused by impact in the movement. It has high-temperature resistance. It's very elastic, and it doesn't deform.The use of thermoplastic materials in these frames provides pretty strength due to their flexible characteristics. It is not easy to deform and change color, making it wear for a longer time. Having no release of chemical residues, it is in line with the European requirements for food-grade materials. The weight is less than half of the weight of the plate frame, 85% of nylon material, reducing the burden of nose bridge, ears, and making wearing more comfortable.
The Cons of Rimless Glasses
As there is no frame around your glasses lenses, the rimless glasses may be more likely to break. If you are not very careful with your glasses, you may have to replace them on a constant basis.
Rimless glasses are higher than other framed glasses because of the details that go into this style. In fact, the rimless style needs more work and time. So, making this kind of style is more time-consuming. So, rimless glasses are expensive than framed glasses.
From the above information, if you like rimless glasses, you can try them. Thus, you can buy them from Koalaeye Optical, which is an online store and provides all kinds of glasses, sunglasses, and frames. So, try Koalaeye glasses and the glasses will be mailed for you with your great convenience.
What are the benefits of Silhouette?
The wonderful style suits both men and women. The glasses are made of strong, reliable, and not heavy metal. They adopt a screw-free design and high-quality process. The glasses are made of titanium alloy temples and are highly ergonomic. They are not heavy and elastic (only 1.8 grams in weight), independent of momentum changes and extreme gravity. The temples and nose pads are made of hypoallergenic titanium alloy. With no screws and hinges, they provide optimal safety in space conditions.
Advantages of progressive multifocal lenses
The progressive multi-focal lens has a number of different focal points from top to bottom. There's a smooth transition between seeing far and seeing close. There is no clear dividing line in the middle, like the myopia glasses, quite beautiful, and it is not dangerous. Because the added value is continuously and slowly increased in the gradient area, the wearer can get a continuous clear vision from the far point to the near point through the progressive lenses with the appropriate head position. In line with physiological optics, They help a better adaptation. Since the lens degree changes little by little, there is no phenomenon like jumping. Because the degree of the lens is gradual, so the vision from far to near changes slowly increase, which will not produce the adjustment of the eye fluctuation. It is not easy to cause visual fatigue. Without a degree line, the appearance will be more beautiful. Clear vision can be obtained at all distances within the visual scope. A pair of glasses satisfies both close and middle distances.
How long do plastic frames last?
Plastic frames are made of non-biodegradable materials and are possible to last forever. If the frame is made of acetate, the layers of acetate fibers make the frame vary in degrees of transparency and pattern. The plastic frame manufacturing process makes the plastic frame more brittle than the acetate frame. In this sense, the acetate frame has a longer service life. Then the plastic, which is made of SAP, will never break down. Depending on the circumstances, it could take years. If the lenses are polycarbonate, the material takes hundreds of years to break down naturally. If TR-90 is normally stored, not exposed to the sun, and put in the box with cloth wrapped, and then you can keep 3 years, there is no effect.
