I recently opted for a pair of Shamir Autograph II to fit in a 33 mm (B) frame, after years of using Varilux Comforts (CR39) in a 31 mm (B) frame. Between the prescription, opticians and lab, it took two eye exams, two fittings and three pairs of lenses before they got everything right, at least per the numbers. While there are things much to like about these lenses, there is one overriding problem. The area that falls in 'mid distance' is blurry. That's from about 20" out to about at least 5 feet, getting worse as it goes out. That includes practical vision areas like the computer screen (33-36") and viewing titles in the library stacks. Just the sort of 'gap' that creates an everyday problem. It was even worse at first, going well into normal reading distance (15-18"),* but the optician ended up leaving aside the fit and pulling the nose pads back so the fame sits directly on my nose and thus reading area is more accessible. This has all come as a surprise, because this wasn't a problem with the previous Comforts (or earlier Shamirs misfitted at 21 mm). The optician's solution is computer glasses. I wonder...
My first question is: Is this problem primarily a function of the change of prescription (my eyes) or more of the nature of the Shamir lens relative to this frame's vertical? The Shamir requires a minimum 19mm fit, mine being fit at 19.5mm. Would I have been better off with something requiring a shorter fit? When I initially mentioned the Autograph IIs, the shop suggested the Zeiss individual, which requires an 18mm minimum (they had done Autographs, but this was their first pair of IIs, and it required using a different lab than they normally use and prefer). Thanks. Rx (for Comforts): OD +0.25 -0.75 100 +2.00 OS +0.50 -1.50 90 +2.00 Current Rx (for Autograph II): OD +0.25 -0.75 90 +2.25 OS +0.50 -1.00 100 +2.25 * The main reason for the follow up eye exam was that the original prescription set up a reading distance of a foot, really 9", which this shop considers normal. They do not recognize how close a foot actually is, and how relatively unusual it is for anyone short of thick lenses to hold material that close. -- Check us out at the oft-updated http://glassyeyes.blogspot.com!
