What are optical eyewear？

Optical eyewear are eyewear used to correct vision problems. They use lenses to adjust light to correct vision problems. According to different vision problems, optical eyewear may have different lenses, such as myopia, farsightedness, astigmatism, etc., usually composed of lenses and frames. The lenses are the main part used to correct vision problems, and the frames are the part that holds the lenses in place in front of the eyes. Frames may come in different materials and shapes such as metal, plastic, mixed materials, etc.

Optical eyewear are usually made and worn with a prescription from an ophthalmologist. During the manufacturing process, the lenses are customized to suit the individual’s vision needs. During the wearing process, the ophthalmologist will adjust the position of the lenses and frames according to the individual’s vision and facial features to ensure that the eyes can see objects correctly.

What are the materials of optical eyewear?

The lenses and frames of optical eyewear can be made of different materials.

Lens Material:

Ordinary Glass: Economical, but breakable.

Plastic lenses: lightweight, scratch-resistant, but not heat-resistant.

Hard plastic lenses: more wear-resistant, but more expensive.

Anti-blue light lens: additionally filter out blue light, which can reduce the damage to the eyes caused by electronic screens.

Frame Material:

Metal: Classic and elegant, durable but can be too heavy.

Plastic: Lightweight and highly malleable, but not resistant to high temperatures.

Hybrid materials such as titanium: lightweight yet durable.

There are also some high-grade materials, such as titanium alloys. Titanium frames are light in weight, have good oxidation resistance, and are not prone to allergies, but they are more expensive.

In addition, there is a material called “anti-glare lens”, which can reduce reflected light and make it more comfortable for the eyes. Such lenses are usually additional coatings on top of other material lenses. There is also a material called “photochromic lens”, which can change the color of the lens according to the change of ambient light, which is suitable for outdoor activities. Finally, there is a material called “conversion lens” that automatically adjusts the clarity of the lens according to changes in ambient light, suitable for driving and other outdoor activities.

In addition to materials, optical eyewear can also have different designs and characteristics.

One of them is a multi-focal lens, which can correct myopia and hyperopia at the same time, and is suitable for dual problems of myopia and hyperopia or for the elderly.

There is also a rotating multi-focal lens, which can adjust the focus by rotating the lens, which is suitable for dual problems of myopia and hyperopia or presbyopia.

There is also an automatic focusing lens, which can automatically adjust the focus according to the distance, which is suitable for the dual problems of myopia and hyperopia or myopia, hyperopia and presbyopia.

There is also a frame with interchangeable lenses, which allows users to exchange lenses as needed, such as suneyewear lenses.

In short, optical eyewear can not only have a variety of materials, but also can have a variety of designs and characteristics. When choosing, you should consider your own needs and economic conditions.
