Advantages of aspheric lenses
In reality, aspheric lenses were originally born to improve the marginalized optical properties of spherical lenses. The aspheric lens with special coating treatment has perfect visual performance, with a clearer, more comfortable visual effect. You can hardly feel the presence of aspheric lenses when you put them on. So you can enjoy the ease brought by aspheric lenses. They are more natural and more realistic, having less visual distortion. The aspheric lens can be designed with a flatter base arc, which not only makes the appearance beautiful but reduces the peripheral magnification so that when others look at the eyes of the people who wear glasses, the size will not change much.
Are carbon fiber glasses better or titanium?
In terms of weight, the titanium frame is very light. The specific gravity of the pure titanium frame is about 4.5g/cm3, and the specific gravity of the titanium alloy frame is about 8.9g/cm3. The pure titanium frame is lighter than the titanium alloy frame. However, carbon fiber glasses are lighter in weight. The carbon fiber glasses launched by LOHO are only 7.87g, which is very light to wear.
In terms of hardness, titanium has a high hardness, about twice that of stainless steel, twice that of iron, and six times that of aluminum. Carbon fiber is lighter than aluminum, harder than steel, and its strength is ten times that of iron.
In other respects, the titanium frame has the advantages of corrosion resistance, acid and alkali resistance, high stability, good elasticity, good toughness, and resistance to deformation. The carbon fiber frame has the advantages of corrosion resistance, high temperature resistance, radiation resistance, good elasticity, good flexibility, and abrasion resistance.
It can be seen from the above comparison that carbon fiber glasses have the general advantages of titanium frames. In terms of weight, carbon fiber glasses are much lighter than ordinary pure titanium glasses.
The shape of the lens is also important.
Aviator and cat-eye glasses should be avoided, as both will cut off the base of the prescription, resulting in poor reading vision. Instead, they should opt for shorter frames with rounded edges, such as bull horn frames, vintage wingtips, round frames, and oval frames.
Agstum Blue Light Blocking Glasses - Flexible Rimless Titanium Alloy Eyeglasses Frames
The frame is equipped with anti-blue light lenses, which you can easily replace with your own if you have eye problems. Blue light-proof lenses are to make you have a better sleep. They are to prevent harmful blue light, which provides all-day protection against the harmful effects of high-energy visible light and UV400. You can enjoy your digital time without worrying about eye strain, blurry vision, and headaches. It uses a durable memory metal optical frame.
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.
How much do a pure titanium eyeglass frame cost?
What’s the probable price of a a pure titanium frame? The price is not the same, due to customer demand. There are pure titanium frames, Beta titanium frames, and half titanium frames. Online shopping is different from physical stores, and online shopping prices are probably only more than 50% of the physical optical stores. The price of the pure titanium frame is more expensive, be in 500 above commonly. The frame of pure titanium appears sedate mature, suiting the man with a successful career quiet. The price of a titanium frame is relatively cheap, usually around 300. The titanium alloy frame is practical and suitable for students. Prices vary depending on the brand, style, material, and even location of the frame. The price of the eyeglass frame is determined by several aspects, like the brand material, the marketing mode, and so on.
What are the features of TR90 glasses?
One of the best features of the TR-90 glasses is impact resistance. If you often drop glasses or accidentally sit on them, this material reduces the impact and the frames will quickly return to their original shape. They are flexible, and can easily show your face. Much lighter than other materials, the feather-light feeling makes them comfortable. Because the TR90 frame has high elasticity and is not easy to break, it has high strength and does not break. The material of TR90 is much more expensive than other PC, CP, and other materials, and the production process is strict, so the price of the TR90 frame is several times more expensive than other frame materials. Because TR90 material has strong wear resistance, chemical resistance, and solvent resistance, it is not easy to be burned. But TR90 material is the most widely used material in China at present, and its safety performance is the best one among all materials.
