Clinical Trials Registration

We are currently recruiting internationally for a limited number of people to take part in our closed and regulated clinical trials taking place between 13-18 October 2013.

If you are an adult with any form of severe eye condition that has resulted in a loss of partial or total vision permanently, we want to hear from you.


Sight status

Visual acuity is acuteness or clearness of vision, which is dependent on the sharpness of the retinal focus within the eye and the sensitivity of the interpretative faculty of the brain. VA is tested by requiring the person whose vision is being tested to identify characters (like letters and numbers) on a chart from a set distance.

Normal visual acuity is commonly referred to as 20/20 vision. This describes how at 20 feet a human eye with nominal performance is able to separate lines that are one arc minute apart.

Total blindness is the complete lack of form and visual light perception and is clinically recorded as NLP, an abbreviation for “no light perception”.

Blindness is defined as visual acuity (vision) of 20/200 or less in the better eye with best correction possible. This means that a blind individual would have to stand 20 feet from an object to see it with the same degree of clarity as a normally sighted person standing at 200 feet.

Partial sight is defined as visual acuity between 20/60 – 20/200.
