hi-minus

[Myoptic33]

I remember attending a seminar by Norvilles several years ago. One of the questions asked at the time was "What is the highest minus lens you have dispensed". Personally I have dispensed a -33.00 as a bonded lenticular. In the audience the highest quoted was -42.00............. Norvilles topped it by a large margin, they had had an order for -96.00, YES you read it correctly, -96.00. To make the lenses thay had to cement 2 lenses back to back and each had an aperture of approx 12mm. A year later they had another order for the same client for -104.00, they physically couldn't make it.

Consensus of opinion was a guide dog or white stick would have been a better bet.

minus 96 diopters? holy is this even possible? I saw one website that says they once made a -70 glasses and they said it was a world record too! His eyes got worse by -8 in one year? Wow whats his corrected vision? something like 20/2000? His uncorrected vision would be LP(light perception)
How much myopia is physically possible? Wouldnt your eyeballs be more than twice as long as normal, your corneas extremely steep, your lenses like three times thicker?

I have a kerataconic 16 year old in -20, but we only made a balance lens for her glasses in that eye, she is an rgp wearer.
I have another lady, an aphakic, who wears +15 permalens and has back up glasses...HIDEOUS!
I think the highest eyeglass rx i ever did was a -17 or so.

it must be the time of year.following on from the high prism thread got an order today for -35.00 -2.00 47mm dia 25 bowl lentic. that tested the generator.
so what is the worst prescription you have been asked to make.

Most everybody has me beat on sphere powers...but I had to fit a -9.00 cyl once(approx +8.00 sph)

Any of you with the weird Rx's have pictures of what those glasses actually looked like when being worn?
