What Types of Eyeglass Lenses Are Available?

The technology for eyeglass lenses advances all the time, and the old fashioned glasses of our grand parents are no comparison to today's high-tech lenses and technologies available. In your grand parents time, all eyeglass lenses were made only of glass.

Today, this is totally different: almost all eyeglasses are made of specially designed high-tech plastics. The new raw marterial is in all spects much betterthant old fashioned glass: Plastic eye glass lenses weigh a lot less, they can be treated with a filter that protects the eyes from tho dangerous and damaging ultraviolet light and plastic eye glass lenses don't break as easily as old fashined glass lenses.

Even compared to the first (common) plastic lenses, today's high tech plastic material that is used to manufacture eyeglass lenses is miles better. You have the choice of diferent technologies, that are all thinner, lighter and more scratch resistant than the ones that are made of the older materials:

Polycarbonate lenses for Eyeglasses

These eyeglass lenses are the tough, impact-resistant type. They are an excellent choice for people who are regularly active in sports, or who work in an environment in which their eyeglasses may be easily scratched or broken. The material is also great eyeglasses for children, the kids often don't pay much attention to their glasses and easily drop and scratch their eyeglasses. An added advantrage of polycarbonate lenses is their ultraviolet protection for the eyes.

Trivex lenses for Eyeglasses

These eyeglass lenses are made from a more recently developed plastic that offers similar characteristics as polycarbonate lenses. These lenses are lightweight, impact-resistant and very thin. For some people Trivex lenses provide a better vision correction than polycarbonate lenses.

High Index Plastic Lenses for Eyeglasses

These eyeglass lenses are designed for people with a need for a high correction who require strong prescriptions. Theese new lenses are much lighter and thinner than the former, thick "coke bottle" lenses that were the norm only a few years back.

Aspheric Lenses for Eyeglasses

Aspheric eyeglass lenses are different from typical lenses, which are manufactured in a spherical shape. Aspheric lenses are constructe4d with differing degrees of curvature over its surface, that allows the lens to be made even thinner and also flatter than other lenses. This construction system creates an eyeglass lens with a much larger usable portion than the usable surface that is usable on a standard lens.

Photochromic Lenses for Eyeglasses

Photochromic lenses can be made from glass or plastic. Photochromic eyeglasses are great when you are often changing from indoors to outdoors: They change from clear to tinted when exposed to sunlight. With Photochromic lenses you don't need to purchase also prescription sunglasses. There is one drawback: Often these eyeglass lenses don't darken in a car because the windshield blocks the ultraviolet rays from the sun.

Polarized Lenses for Sunglasses.

You know the situation: Looking out over water can be blinding... Light reflected from water or any other flat surface can cause nasty glare. Polarized lenses reduce this glare and are popular among people in sports and for driving. Polarized lenses may make it difficult to read the liquid crystal displays on the dashboard of cars.

Depending on the type of vision problem that you might have, the shape of the eyeglass lens needs to be different. For example, a lens that is concave, means it curves inward, is used to correct nearsightedness (myopia), on the other hand, a lens that is convex, means it curves outward, is used to correct farsightedness (hyperopia). To correct an astigmatism, that is caused by different distortions in the shape of the cornea, mostly cylinder shaped lenses are used. We can sum up the function of an eyeglass lens like this. It is the tool that help you to focus light correctly onto your retina so that you see clear.
