Allan Fradkin, M.D. commented on how the application of optical physics might be helpful to patients with AMD, or age related macular degeneration, in regaining some functioning vision to overcome the visual distortion caused by AMD. bns gold “While the key to maintaining eye health and vision as we age-especially regarding macular degeneration-is having regular eye exams, there are still a growing number of patients who experience a disturbing distortion and twisting of their vision resulting from macular degeneration,” explained Dr. Fradkin.

Nobel Laureate Walter Kohn described a potential application of what is a dynamic “translator” for the particular distortion a patient experiences either in handheld computers or an optical corrective lens. “We routinely use the Amsler Grid, a graph-paper-like pattern to diagnose AMD-Dr. ugg classic mini Kohn suggested that the Amsler grid could also be used to develop an optical correction,” said Dr. Fradkin.

When people with healthy eyes look at the Amsler Grid, they see its straight horizontal and vertical lines, with a dot at center. Patients with AMD, however, often perceive a distortion about two or three centimeters in diameter in the center.

Dr. Adidas Soldes Kohn has initiated the development of software that lets an AMD patient, using a mouse, pull the virtual lines until he or she perceives the grid as “perfect,” yielding reversal of the specific distortion a person experiences. Dr. Adidas Running Kohn then uses these results to create a correction for that patient. adidas zx flux In one experimental device, a handheld computer scans the printed page, using software to perform dynamic compensation, distorting the text to make it readable for patients. In addition, Dr. adidas pas cher Kohn uses of a slab of optical material to fabricate the visual correction so that AMD patients could hold the optical slab of refractive material over text, pictures or reading material, just like the magnifying glass people use for seeing small type—only the surface of Kohn’s slab resembles ocean currents or waves that reverse the distortion.
