Their acuity ranges from 20/40 to 20/800, although they should preferably be used for individuals who have a vision of 20/400 or greater. Patients who have trouble seeing standard print are usually given low vision glasses. As a result, a thorough low vision exam is usually performed in order to create a unique design for you. Driving and needlepoint, for example, require distinct magnification requirements, necessitating the creation of specialized low vision glasses for each. Most low vision glasses have sophisticated optics that are tailored to your specific poor vision needs and the tasks you wish to accomplish with them. The magnification power, field of vision, and weight of low vision eyeglasses vary depending on the wearer. If your vision impairment is beyond the limit of correction with traditional prescription glasses or lenses, your doctor will most likely recommend ‘Low Vision Glasses,’ which are a kind of visual aid with magnification characteristics to help you overcome your low vision.
Low vision is defined as a BVCA (best-corrected visual acuity) of less than 20/70 in the better-seeing eye.
