Many sports today are high-risk enough so that protective equipment is necessary, so sports glasses become quite common in the athletic world. Other types of sports glasses are prescription sports glasses for people who wear regular prescription eyeglasses. These prescription sports glasses are also impact-resistant and often secured to the head by a headband made from elastic materials, and the lenses can be changed as one’s prescription strength changes.

The most important factor for you to purchase a pair of prescription sports glasses is the lens material. Polycarbonate lenses are the best choice, as they are impact-resistant and resistant to scratching. Glasses lenses should be avoided, as they can shatter and cause injury. The frames of the prescription sports glasses can be made from plastic, carbon or other composite materials. Choose a pair that is lightweight, well-constructed, and if possible, shatter resistant. Be prepared to spend more on a good pair of glasses, especially if you are interested in name-brand products. Less expensive, non-brand name glasses may work just as well, but be sure to research the glasses you choose.

Sports glasses are made in a variety of shapes and sizes. Many are designed for racquet sports and are available for basketball and soccer. Some are even designed to fit in helmets used for football, hockey and baseball. Different sports requires different sports glasses. For example, when participating in high impact sports such as soccer or hockey, be sure to choose a pair of sports prescription glasses that feature some sort of elastic securing band to wrap around the head. Earpieces are often not enough to hold the glasses in place, so an elastic securing system is necessary to keep the glasses securely fastened to the face. Since these types of glasses will fit fairly snugly to the face, you may want to choose a design that features vents at the sides of the lenses to prevent fogging from sweat. When it comes to low impact sports or sports that will not jostle the participant around too much such as cycling or running will require glasses that is lightweight and comfortable.
