Why should you choose thin lenses?

Regular lenses are great for low-prescription people, but for high-prescription people, high-prescription regular lenses are too thick and heavy, making them unattractive and have a poor wearing experience. For high-prescription people, we recommend that they choose thin lenses with a high refractive index because they are lighter and more attractive to wear. For any astigmatism above +3.00, we recommend 1.67 or 1.74 refractive index lenses because these lenses are aspherical in design, which means they are thinner, flatter, and lighter than standard spherical lenses, which reduces the magnification of your eyes to other people.


How do drivers wear glasses or sunglasses better?

We should pay attention to the dim light at night on the impact of vision, At night, for the people who wear glasses, it is best not to drive, but to prevent fatigued driving. If you need to drive, you must choose clear and appropriate optical glasses. When the light is strong in the field, it is advocated to wear light-colored sunglasses with appropriate degrees to ensure driving safety.

What difference do mono-focal glasses and multi-focal glasses have?

A mono-focal lens is a lens with one focal point. Usually, the myopic far-sighted presbyopia that we see belongs to mono-focal glasses. There is only one diopter on one lens, and this is the single focal point. Multi-focal glasses are lenses that have multiple focal points, that is, multiple diopters. Both mono-focal glasses and multi-focal glasses are visual correction tools, but mono-focal glasses can meet basic vision needs, like fatigue relief, control of depth of diopters, and focus on different distances such as the need to see far and near.But because there are many different diopters on a multi-focal glasses lens, so the elderly can not only see far after wearing. When they see close distance, they do not need to take off glasses or wear reading glasses. Wearing multi-focal glasses is not easy to fatigue.


What should drivers notice when wearing polarized glasses?

Many drivers like to wear polarized lenses. Indeed, the polarized lens can reduce strong light, eliminate glare, so that the line of sight is natural and soft, but the polarized lens is more suitable for fishing, skiing, and other large areas of the reflective environment.

In addition, polarized lenses can make LCD screens and LED traffic lights dim. Therefore, when choosing polarizers, it is best to choose good quality optics, and when going through the tunnel, it is best to take off your glasses ahead of time and blink a lot. Before wearing the driver polarizing lens, try it on and observe whether the polarizing film of the lens is smooth.

Keyhole glasses are different from saddle glasses.

Glasses without nasal pads are common, usually with plastic eyewear frames and metal frames. Plastic frames without nose pads usually have a saddle-shaped nose area, therefore this type of bridge is called a saddle bridge. The keyhole is designed to touch the two points of the bridge of the nose, eliminating pressure from the top of the nose. This style is a bold fashion statement for both men and women.
