My son wishes to persue a career in commercial aviation.
Searched the CAA website and on the subject of distance vison they say....
"Your visual acuity (measured by your ability to see, in this case, lines of letters on a chart at 6 metres) must be at least 6/9 in each eye separately and 6/6 using both eyes together, with or without glasses or contact lenses (correction). If you need correction the refractive error (the amount of correction) must not exceed +5.00 dioptres of long sight or -6.00 dioptres of short sight. This is in the most ametropic meridian (taking into account any astigmatism). Astigmatism must not exceed 2.00 dioptres. The difference in correction between each eye (anisometropia) must not be more than 2.00 dioptres. Your optometrist will be able to explain these terms."
His glasses prescription late last year was
Right eye distance - sph + 2.75 cyl -1.0 axis 85.0
Left eye distance - sph + 0.5 cyl blank axis blank
There are no units on this prescription. Are the units dioptres...is he likely to get the nod.
If he is unlikely to meet the class one requirements I will point him in another direction.
Any help much appreciated.
