Lenses can be divided into PC lenses, CR39 resin lenses, Nylon lenses, AC lenses (acrylic) according to different materials. Different types of frames are suitable for different lenses. For example, metal eyewear are suitable for nylon lenses and CR39 lenses, and horn eyewear are suitable for CR39 lenses. So, Which is the best lenses acetate sunglasses? Now, let’s study together and find out What lenses are suitable for acetate sunglasses. 

Best  sunglasses lenses 1: CR39 Sunlens. CR39 Sunlens is a kind of lens widely used in acetate sunglasses, with high definition and hardness. The color of CR39 film is very rich, and the coating color can also be added on the surface to make the color more beautiful. The high-end CR39 Sunlens can block most of the ultraviolet rays and can protect your eyes well. CR39 lens is one of the most suitable lenses for acetate sunglasses.

Best sunglasses lenses 2: Nylon lenses. Nylon lenses has strong toughness, and also has good light transmittance and hardness, but its light transmittance is slightly lower than CR39 lenses. Nylon lenses are also often used in acetate sunglasses. Because nylon lenses have good toughness, they are especially suitable for use in half-rims, rimless frames or those with perforated lenses. Especially for some metal sunglasses with irregular lens shapes, nylon lenses must be used. At the same time, nylon lenses also have a good anti-UV function, which is the same as CR39.

Best sunglasses lenses 3: Glass lenses. Glass Lenses made of this material have the best clarity and hardness than other lenses, at the same time it is heavier than other lenses. But it is not easy to cut pieces because of its hardness which cause some difficulties for eyewear manufacturer during production. The manufacturing process and dyeing process of glass lenses is a little complicated , so the curvature and color choices of glass lenses is quite limited. The eyewear with glass lenses are held in the hand, and they have a heavy feeling, and they have also been liked by some consumers.

In addition, remind me that PC lenses are not very suitable for acetate sunglasses，the material of acetate eyewear is mainly made of cellulose acetate fiber, which will set off a chemical reaction and lead to the PC lenses to be broken easily after they contact with each other for a long time. So please pay great attention to this point.

Each type of lens has its most matched eyewear style. For example, CR39 lenses is best acetate sunglasses lenses; PC lenses is applicable for plastic sunglasses and metal sunglasses; For rimless frames or half-rim frames with lenses punched( such as metal eyewear), Nylon lenses is more applicable for them; AC lenses is often used for optical frames; As a eyewear manufacturer in china, when assembling lenses, we will use the most suitable lenses according to the material, structure, shape, etc.
