June 23rd, 2015

Plastic glasses can be supposed to plastic frame glasses and glasses with plastic lenses. When it comes to plastic frame glasses, these frames are usually made from zylonite, cellulose acetate or nylon. They are lightweight, strong, flexible, hypoallergenic, corrosion resistant and available in a variety of styles and patterns such as rimless frames, semi-rimless frames. Plastic frame materials are better suited for people with active lifestyles and vibrant personalities. These frames come in a variety of colors and styles, making them a creative option for eyewear. Plastic materials are also commonly used in performance and sport eyewear frames. Plastic performance frames are lightweight and durable, which is why they are favored by athletes and people who participate in outdoor and recreational activities.

However, if referring to glasses with plastic lenses, these lenses are far lighter than glass, making them less likely to indentations on the nose, while lenses made from plastic sit much more lightly. Plastic lenses are impact resistant, making them a better choice for children, active adults, sportswear, and safety wear. It takes a far greater force to break this type of lens than a comparable glass lens, and while glass shatters, plastic will more likely dent, or if the force is great enough, crack without shattering. Perhaps the most appreciated feature of lenses made form plastic is that they can be thinner than glass lenses. Those with strong prescriptions know how thick glass lenses can distort the face. Thick nearsighted lenses significantly reduce the size of the eyes, detracting from the natural appearance of the wearer. A nearsighted lens is also wider at the edges than in the middle, making the edges noticeable in fashionable wire frames or frameless glasses. A thick farsighted lens is wider in the middle and narrow at the edges. The wide middle magnifies the eyes, resulting in an owlish look.

For people with strong prescriptions, high index plastic lenses are a great choice. These lenses can be thinner, because they bend more light than glass or normal plastic. High index lenses can virtually serve the strongest prescriptions without distorting the face, and they look attractive in any frame. No one will ever guess how strong your prescription really is! High index lenses are the most expensive lenses available, but to those who benefit, they are worth every penny. If you have struggled with coke bottle glasses or have forgone glasses in certain situations, embarrassed by how they made you look, you will likely love these lenses. For those who need little vision correction, normal plastic lenses will deliver all of the benefits of plastic at a lower cost than high index lenses.
