At present, there are optical glass sheets, ordinary resin sheets, high folding resin sheets, or PC lenses on the eyeglass mart. Ordinary glass lenses are cheaper and scratch-resistant.

Resin and PC lenses are lighter and less fragile, especially PC lenses, which can relieve pain such as rhinitis and headache caused by nasal bridge compression, and are safer for people who love sports.

From an aesthetic perspective, high-folding resin sheets should be selected for height, and high-folding glass sheets can also be chosen. For wire drawing and frameless punching frames, resin lenses are more suitable.

Try to choose lenses with the highest refractive index, such as 1.74 or even 1.76. If the budget is sufficient, it is also possible to consider double non-spherical lenses. At least one lens with a refractive index of 1.67.

Choosing the best place to buy eyeglasses processing, such as fire pure green polishing technology, can cut off a part of the edge thickness of the lens and then polish it, which is commonly known as edge-cutting beauty in the industry.

Choosing to turn thin glass lenses, there are currently customized thin glass lenses available on the eyeglass mart. With the use of high refractive index materials, the glass bottle bottom lenses can be made thin through turning technology.

It should be noted that this type of lens requires the selection of a good frame, with frame size and pupil distance preferably close, and pupil height preferably close to the center. Then, the lens should be designed based on the size of the frame, frame parameters, and pupil distance.

The material of the frame should be lightweight as as possible, the contact angle of the nose pad should be just right, and the contact area should be larger. The front and rear configuration of the frame should be balanced.
