If you cannot achieve sharp vision even with regular eye glasses, contact lenses or intraocular implants, you may be suffering from low vision. This condition can be improved with the help of magnification devices or low vision prescription eyeglasses.
Having low vision is no longer going to hamper those who want to lead a normal lifestyle. You will not have to stay indoors or depend on other people to do your work. The latest devices for low vision correction enable your eyes to function well in the outdoors.
Many people complain of light and glare sensitivity, particularly those with cataract, macular degeneration or diabetic retinopathy. For greater comfort, you can wear special glare-reducing and blue-blocking lenses in sunny as well as cloudy weather. These are available in yellow, orange, grey and various other shades of amber.
Photochromic glasses can lighten or darken according to the amount of sunlight. Before recommending any option, your low vision specialist or eye doctor will consider the lens colors, blue light absorption capability and percentage of light transmission. Glare-reducing and blue-blocking lenses can be alone or over your glasses in the form of clip-ons, side-fitting styles or prescription sunglasses.
Another advanced alternative that is recommended by eye specialists in extreme cases is use of eyeglass-mounted telescopes for which you will need a prescription from your doctor along with special training. If you are unable to see clearly while driving, watching TV, sporting events or objects at a distance, a small telescope can help in correcting the problem. Provided in many powers and styles, telescopes can be hand held, attached to finger ring, neck cord or mounted in your eyeglasses.
The patients’ hands remain free when the telescope is mounted in an eyeglass frame. These telescopes may be standard and pre-made or customized to particular needs of the patient. Both the eyeglass prescription and telescope can be used when it is mounted in the top of the eyeglass lens.
Nowadays, head-mounted electronic magnifying glasses are also being used for automatic focusing. Canes can also be used to navigate unpaved areas and maintain your balance in case of weak peripheral vision.
