What does it do?

EveryEye uses data from scientific studies of partial sightedness together with cutting edge image processing technology so that at the touch of button you can view the whole screen as an older or colour-blind person would see it.

Fast and easy to use

Promote your commitment to accessibility with ready to use presentation materials

EveryEye comes with ready to use presentation and sales materials. We make it easy for you to promote your services. You can use these materials in your presentations and sales literature to let people know that what you produce is tuned to work with an extra 28% of the population.

Use the included audit template to rapidly turn around site audits

EveryEye also comes with ready to use audit templates which allow you present screenshot taken using EveryEye alongside well strucutred descriptons of the problems you have spotted using EveryEye.

Based on solid scientific foundations

EveryEye is based on a precise understanding of the visual impairments experienced by older and colour blind people. This is based gained on authoritative scientific studies that are the culmination of years of research in vision science, optometry and ophthalmology.

Uses advanced image processing algorithms

Getting a computer to simulate human vision in real time is no small feat. The algorithms behind EveryEye have been designed by a specialist in real time image processing and the simulation of human vision.

To simulate the effect of age on sight we used scientific measurments from exisiting research and our own image processing algorithms. There are precise measurements of the decline in vision with age. Using specially written fitting algorithms we have been able to arrive at a computationally efficient mathematical function which closely matches the data on old age vision. The approach we have taken is superior to previous, academic, work on this problem. Its non-statistical basis makes it more principled, and therefore more accurate and scientificaly valid.

To simulate colour-blindness we have made us of an algorithm put forward in recent research. Essentially this reproduces the colour perceptions of who are missing their green or red receptors, in other words the truly colour-blind. This allows the designer to examine the worst-case scenario for colour blindness. A design that works for the truly colour blind, will definitely be fine for those who are colour insensitive.
