ML FILTERS FOR ELDERLY

You meet them every day in your clinics and stores. The people with great maturity and wisdom of life but insidious vision deterioration. Unfortunately, it is difficult to get away from the natural ageing of the body and eye, but many tools can increase the quality of life for the elderly. One of them is filters.

Contrast vision deteriorates with age

Age affects the contrast vision and it deteriorates the older we get, regardless of whether we have normal vision or have an eye disease. (see table on page 74). Both contrast vision and light conditions have a great impact on visual acuity, not least in the oldest age groups (> 84 years). Their visual acuity is halved at low contrast conditions. If they in addition are exposed to glare, only ten per cent of vision remains. In the blue bars, you can see the difference in visual acuity between high and low contrast. The orange bars show the visual acuity with glare.

Photosensitivity common among the elderly

With age, the retina also becomes more sensitive to disturbing light, both blue light and glare. Many people wear regular sunglasses to alleviate their discomfort. But sunglasses dim all light, across the spectrum, and often become too dark for an elderly person who is dependent on good light.

Filter sunglasses

By cutting away the unwanted light with a filter and adding a slight polarisation instead, the glasses become significantly brighter than ordinary sunglasses. Filter sunglasses give the client the right amount of light, good protection, and high contrast.
