Visual impairments explained
EveryEye is based on the fruits of many years of scientific study in the fields of gerontology, ophthalmology, optometry and vision science. Here we explain what these fields tell us about age related vision loss and colour blindness.
Age related vision loss
From the age of about 40 degenerative changes in the optical and neural characteristics of the visual system result in a steady but complex decrease in visual acuity. Put more simply as people age their vision becomes more blurred; they can see big things just as well, but have difficulty with the details.
Colour blindness
Colour-blindness manifests itself as an inability to distinguish reds and greens. It results from problems with cells on the retina that are receptive to red or green light.
