Low vision can result from eye diseases or injuries to the eye.
But they have lost their vision to the extent that it cannot be corrected well enough with glasses, contact lenses, medication or surgery. Modern technology has developed a number of devices that enable people to make the best use of the vision they have. These devices are called low vision aids. Most people with low vision can continue to lead active and independent lives with these devices, which restore their ability to read, travel, care for themselves and enjoy their surroundings. Eye doctors or eye clinics can refer people to low-vision centers.
