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.

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.
