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.


What Are Progressive Glasses?

Trifocal glasses and no-line progressive lenses are multi-focal glasses, meaning that their lenses offer multiple correction fields. Whether you have been wearing multi-focal glasses for a while, or you have just begun to look at options for correcting vision after 40 years old, you may have heard the terms trifocal or progressive glasses.

Progressive lenses offer a smooth transition from distance vision through intermediate vision to near vision, and they supply all the in-between corrections. Progressive lenses have three different viewing zones, as trifocal glasses do, and they have progressive powers of corrections, easing eye strain and providing the most natural vision correction.

How many degrees of myopia do I need to wear glasses?

Students are the most nearsighted because they need to read and study every day. Many people have myopia during their student days. During the physical examination, everyone will check their eyesight first. Generally speaking, if the visual acuity is lower than 0.6, it means that you may be near-sighted to 0 degrees. At this time, you need to go for optometry to see the specific vision situation and see if you need to wear glasses. If the visual acuity tested exceeds 200 degrees, you must wear glasses at this time. If you do not wear glasses, your vision will be greatly affected, and the degree of myopia will rise quickly. For this reason, you must wear glasses in time to correct your vision. If the degree of myopia does not exceed 0 degrees, this is pseudo-myopia and does not require glasses. However, you should always take care to protect your eyes, avoid staring at things at close range for a long time, and don't let your eyes get too tired, so your vision will slowly return to normal.

What are the benefits of memory metal frames?

Memory metal materials are inherently lighter than metal materials, which can reduce the pressure on the bridge of the nose and skin. The memory metal frame is super elastic, so it never deforms, and it is so apparent that the temples on both sides of the frame line up with the ring. Because the bending can be automatically restored to its original state, the stability is comparatively strong. It has the benefits of high-temperature resistance, corrosion resistance, which will not cause skin allergy, and so on. It is a hypoallergenic lightweight metal for eyeglass frames that is strong and flexible. It is resistant to corrosion, making it proper for people who work, live or play sports in all kinds of outdoor weather conditions. The memory metal can be placed on the side of the face, making it easier and more comfortable to wear. The memory temples can freely rebound 180 degrees without deformation, making up for the insufficient effect of elastic β titanium. This kind of frame is not able to recover due to careless bending, and it has the function of restoring shape itself.
