The difference and connection between sunglasses and optical frame glasses

The Difference:

Sunglasses consist of a frame and lenses, which are mainly used to block sunlight and decorate. Most of the lenses are colored flat lenses. However, the choice of mirror materials and frame technology are generally not very particular, and the corresponding consumer wearing years are also one or two seasons. Sales of sunglasses have obvious seasonality.

Optical frames generally only refer to frames, which are mainly suitable for fitting photometric glasses. No matter the mirror material or production process, there are high requirements.

Connect:

Ordinary optical frames can also be used as sunglasses after being equipped with full-color or half-color resin lenses and glass lenses, and can be photometrically made into myopia sunglasses.

The frames of some medium and high-end sunglasses meet or even exceed the standard of optical frames, and can be used as optical frames.

Material of sunglasses frame:

Similar to general optical glasses, it is mainly divided into two parts: plastic material and metal material. The difference is that the proportion of plastic material frame is higher.

Plastic materials - acetate, propionate, nylon, collone, carbon fiber, etc.

Metal materials - hard bronze, white copper, manganese-nickel alloy, titanium alloy, pure titanium, gold clad, K gold, etc.
