Safety glasses are usually made with shatter-resistant plastic lenses to protect the eye from flying debris. Although safety lenses may be constructed from a variety of materials of various impact resistance, certain standards suggest that they maintain a minimum 1 millimeter thickness at the thinnest point, regardless of material. Safety glasses can vary in the level of protection they provide. For example, those used in medicine may be expected to protect against blood splatter while safety glasses in a factory might have stronger lenses and a stronger frame with additional shields at the temples. The lenses of safety glasses can ... be shaped for correction.

If you do need to wear eye glasses, they are so great looking today that they have become a fashion accessory in their own right. Every clothing designer has his or her name on frames these days. Frames are available in many styles and price ranges. After getting your eyes tested, the optometrist or ophthalmologist will give you the prescription for the lenses so you can go elsewhere if you don't like the selection of frames they have for sale there. Don't feel pressured into buying frames at the place you get your eyes examined. You can have an optician fill the prescription at any place that sells eye glasses.

[One] unpopular aspect of glasses is their inconvenience. Even through the creation of light frames, such as those made of titanium, very flexible frames, and new lens materials and optical coatings, glasses can still cause problems during rigorous sports. The lenses can become greasy or trap vapour when eating hot food, swimming, walking in rain or rapid temperature changes (such as walking into a warm building from cold temperatures outside), reducing visibility significantly. Scraping, fracturing, or breakage of the lenses require time-consuming and costly professional repair, though modern plastic lenses are almost indestructible and very scratch-resistant.

To be rated as safety glasses, both frame and lenses must adhere to particular ANSI standards. The frames are sturdier than "dress frames," and the lenses must be able to pass a "drop ball" test. Just as the name implies, the test involves dropping a hard ball onto the lens from a certain height. If the lens cracks or shatters, it fails the test, possibly because it's too thin or the material is defective. Any eyecare practitioner who sells safety glasses should be familiar with these standards.
