lawyerboy&you want it when: Slight misunderstanding. I didn't mean add two eyes together, I meant the astigmatic factor and your prescription for each eye individually. Over the age of 25 as long as each eye is less than -5 you are both ok(-3 for under 25. Go to [URL=www.srg.caa.co.uk]web page for info.

If you have any probs with getting results interpreted drop me an e-mail.
