Why not use the normal (Snellen) eye chart?
As far as is known, no similar personal vision screener exists on the market and this is confirmed by our links already established with prominent distributors.Outside of the professional Opticians consulting rooms and the high cost capital equipment there is only the Snellen eye chart at the more ‘public’ level i.e. Doctor’s surgeries/ Health ClinicsCurrently we do not have any comparisons with the Snellen chart but a lot of information exists that highlights the short comings of the chart.The chart was developed 150 years ago to test ‘distance’ vision but it is not a measure of all visual function.”There are quite a few patients who have excellent vision in a doctor’s office when they are looking at a very high-contrast chart.
