optical prescription over the years
Dear all,
Am due to commence training shortly. I currently just pass the Class 1 unaided - my question is, how much does eye power deteriorate every year? Is there a set pattern? I'm worried about losing my licence, say 5/10 years into flying because my prescription exceeds the limits.
Isn't the limit +/- 5 dioptres? Is this a lot of leeway or what could be easily clocked up by gradual reduction in my optical standards over 5/10 years?
Thoughts if you please.
RSE.
