Countless eye injuries could be prevented every day if more Americans wore prescription safety bifocal eyeglasses. People who need prescription eyeglasses in order to read often make the mistake of having one set of frames for vision protection and and another for vision correction. One pair of glasses can offer both magnification and protection, while also addressing both farsightedness and nearsightedness.
About Prescription Safety Bifocal Eyeglasses
Protective bifocals, known as safety readers, have a prescription magnification only in the bottom half of the lens; the lower half of the lens corrects short-distance vision, and the upper portion has no correction. Some protective bifocals correct long-distance viewing in the top half of the lens and short-distance eyesight in the bottom half. With both types of bifocals, the wearer doesn't have to change glasses in order to read.
Not surprisingly, safety readers are much more affordable than protective bifocals that have prescriptions in both the top and bottom halves of the lens.
Safety reader frames usually don't wrap all the way around the lenses, and sometimes the lens portion is actually just one piece that wraps around the face. The frame and lenses are molded to fit the face snugly and protect the eyes from all angles. Tinted safety readers can protect against up to 99 percent of the sun's ultraviolet rays.
Strength and Availability
There's greater availability of safety readers with lower magnifications, typically in the range of +1 to +2.5 . Lenses with stronger magnification need special ordering and typically cost a lot more. You can find the lower-strength safety readers in many hardware stores and building supply outlets, while you'll have to seek out specialty optical retailers to find stronger safety readers.
