The type of material used in sunglasses can have a big impact on the design and functionality of the eyewear. Glass and plastic are the two most widely used materials for sunglasses. The initial material for sunglasses was glass, but because to its fragility and weight, it has become less popular. Due to its strength, affordability, and light weight, plastic is currently the most preferred material for sunglasses.
Sunglasses can be made of many various plastics, but some of the most popular ones are nylon, CR-39, and polycarbonate. Because it is shatterproof, polycarbonate is a common material for sports sunglasses. CR-39 is a preferred material for fashion sunglasses since it is lighter than other options. Another impact-resistant, lightweight material that works well for sports and outdoor activities is nylon.
In terms of fashion, cat-eye and large frames, as well as retro-inspired designs, are once again popular in 2020. Along with more unusual shapes like hexagonal and geometric patterns, aviator and circular frame styles are also popular options. The eyewear sector has also seen a movement toward sustainability, with more companies producing environmentally friendly choices composed of recycled materials.
In conclusion, a select few large companies control the eyeglasses market, with Luxottica holding the vast majority of well-known eyewear brands. Due to its strength and low cost, plastic is the most preferred material for sunglasses. Polycarbonate, CR-39, and nylon are popular options. Retro-inspired styles and environmentally friendly options are popular selections for 2020.
