Low Vision Aid for People with Macular Degeneration and Retinitis Pigmentosa

Millions of people in the US have age related Macular Degeneration, and other low vision diseases that have caused permanent loss of central vision. The SightMate LV920 viewer can help many of these individuals with inoperable visual impairments improve their visual acuity and quality of life.

The SightMate LV920 viewer is a portable, lightweight video magnifier that optimizes residual peripheral vision. Private clinical trials show that people with between 20/70 to 20/200 acuity in their best eye have been able to increase their reading and distance acuity to 20/40 or even 20/20!

By a combination of edge detection (contrast enhancement), color blindness compensation and a zoom capability of 20x, the SightMate LV920 viewer will also assist people with Diabetic Retinopathy or Glaucoma who have suffered a gradual loss over the entire vision field.

SightMate is intended to be worn while sitting. It is not designed to be used in mobile activities of any kind such as walking, playing sports or driving. SightMate is not designed to restore vision, correct eye conditions or halt degenerative vision loss. Please see your vision professional to determine if SightMate is appropriate for you.

As people continue to live longer, the incidence of eye disease such as macular degeneration is on the rise. These types of debilitating eye diseases rob people of vision, and can result in individuals losing their independence.

It is believed that the visual system requires up to 25% of the nutrients we take into our bodies in order to stay healthy. Impaired circulation and/or poor absorption of nutrients can significantly contribute to eye disease. Regular exercise and management of emotional stress are also critical for maintaining health.

Eye conditions/diseases such as macular degeneration, glaucoma, diabetic retinopathy, cataracts and may others can be responsive to specific nutritional supplementation

For example. there is a great deal of peer review research now showing the vision can be preserved through a proper diet and specific nutritional supplementation, and that macular degeneration is a nutritionally responsive eye disease.

The recent B vitamin study showing that those that supplement with B6, B12 and folic acid have a significant lower risk of getting macular degeneration is one of many studies proving macular degeneration to be a nutritionally responsive eye disease.

Essential nutrients include lutein, zeaxanthin, omega-3 fatty acids, taurine, gingko biloba, lycopene, vitamin A, E, zinc, copper, selenium for example, that can help both prevent the onset of eye disease such as macular degeneration as well as help preserve vision for those with macular degeneration.

Daily eye exercises also help maintain healthy vision. For a demo of 3 great eye exercises by Dr. Grossman, one of the Country's leading behavioral optometrists, go to
