Low vision is a visual impairment that cannot be fully corrected with regular eyeglasses, contact lenses, medication or surgery. Despite all conventional treatment, vision remains blurred or distorted, and it interferes with the ability to perform every day activities such as reading, writing, and shopping. Millions of Americans lose some of their vision every year due to a variety of eye conditions such as Diabetic Retinopathy, Glaucoma, Macular Degeneration or Retinitis Pigmentosa. If you are among the growing number of people living with low vision,you can still live independently with the help of low vision aids.
Keratoconus is a progressive eye condition in which the cornea of the eye thins and begins to bulge into a cone-like shape. The cornea is the transparent front part of the eye that covers the iris, pupil and anterior chamber. Together with the eye’s lens, the cornea reflects light. The cornea is responsible for approximately two-thirds of the eye’s total optical power.Read more!

Albinism refers to a group of conditions in which people have little or no pigment in their eyes, skin or hair. Albinism occurs due to inherited altered genes which do not make the usual amounts of pigment called ‘melanin’. Based on the amount of melanin in the eyes, different types of albinism can be distinguished. What the different types have in common is that they are all associated with vision problems.Read more!
Refractive errors are errors in which the eye’s ability to focus light is affected, causing reduced visual capacity. This is the most common and well-known eye condition including various types.Read more!
Usher Syndrome is the most common condition affecting both vision and hearing. It is a rare genetic disorder that is the main cause of deaf-blindness. The major symptoms of Usher Syndrome are loss of hearing and an eye condition called Retinitis Pigmentosa.Read more!
Stargardt’s Disease is an inherited eye disorder that causes loss of central vision at a young age. It affects the macula, the area of the eye responsible for central vision and seeing colour and fine details. The symptoms are very similar to Age-Related Macular Degeneration. Stargardt’s Disease causes progressive vision loss and, in some cases, near blindness.Read more!
