Different Visual Acuity Measuring Systems?
Hi,
I'm from England and have recently applied to Skyguide in Switzerland to be an ATC. They sent me a visual performance form to be filled out.
Here in the UK for Distance Vision I am 6/5 in both eyes and 6/4 for binocular vision however these values don't fit on the Swiss form as it requires minimum values of 0.7.
Does anyone know what system is used in Switzerland to measure visual acuity/does anyone have a formula to work the values out from the UK ones?
I did ask my optician but the values she worked out were incorrect and would put me under the minimum threshold which I'm not (I don't wear glasses and have no prescription).
Any answers are v. much appreciated!! Thankyou!!
