Eyeglasses and Lenses – material, features and benefits

At first, you must understand and accept the importance of choosing the right eyeglass for your eyesight, comfort and appearance. Generally, an eyeglass influences four factors of your personality, namely comfort, appearance, safety, and vision. Hence important is to consult an expert before you head to buy glasses for you.

And during the process, you might need to take tips from your knowledge on certain aspects of eyewear. Here we will discuss these important features to develop your familiarity with this eyewear before you head to buy one.

The glasses lenses

In the beginning, all the glasses lenses were made of a standard type of glass. Hence there was nothing to think or worry about. The glasses lenses are responsible for offering exceptional optics. But they are heavy and can easily break. as a result, they can cause potential damage to the eye if they break while you are wearing them. There were times when such incidents resulted in the permanent loss of an eye. We believe this is one of the reasons why these standard optic glasses are not a preferable choice for doctors and wearers. As a result, many alternative options are secure, economical, and long-lasting. Plus they do not cause any risk or damage to the eye.

Plastic lenses for eyeglasses

It was 1947 when the Armorlite Lens Company from California introduced relatively lightweight plastic eyeglass lenses. These lenses were made of a plastic polymer commonly known as CR-39 (this is an abbreviation for Columbia Resin 39). This lens type is the 39th formulation of a thermal cured plastic developed by PPG Industries in early 1940. these lenses are considered ideal for their properties like lightweight (the weight of plastic lenses is almost half of the weight of glass) and incredibly low cost. Apart from such features these lenses also offer excellent optical qualities. Hence, making the CR-39 a popular option for eyeglasses lenses even on this date.

The high index plastic lenses for eyewear

for almost 20 years, the demand for thinner, delicate-looking yet durable eyewear has increased. To address the needs and demands of such users, brands invested themselves in creating lighter eyeglasses resulting in producing high-index plastic lenses. These are a special type of plastic lenses that are thinner and lighter than the CR-39 plastic lenses. It is because they have a comparatively higher index of reflection. And in some cases, they do have lower specific gravity. These features can help you use a thinner glass even for a higher sight issue. For such reason, this type of eyeglass is popular among people who have a higher number for sight correction.

The polycarbonate lenses

These lenses came forth in the 1970s. It was the Gentex Corporation that introduced the very first polycarbonate lenses for safety glasses. Later in the 1980s, these polycarbonate lenses become massively famous and are still among the top priorities of the users. These lenses were initially developed for helmet visors for the air force. Later they became part of bulletproof glass for banks and many other safety applications. The polycarbonate is ideally lightweight and has a significant impact resistance than the CR 39 plastic. Such properties make the polycarbonate lenses an ideal option for younger kids (who cannot take care of themselves) sports eyewear and safety glasses for work.
