Not too sure what you mean by changing angle... The biggest reading ive had in one eye so far is -0.5. A test at christmas said I was zero in my left eye and -0.12 in my right, then 3 weeks later left eye was -0.25 and right eye -0.?!
Ive got nearly 6/4 vision in distance so it is purely the astigmatism thats screwing things up. Have another date for selection at cranwell in may so need to act fast if anyone knows how to help?!
Cheers
