Good question, but not one I have the answer to. I tried hooping without my glasses but it makes me feel weird and also as you say, enhances the dizzy effect beyond the tolerable.

I have given up and keep the glasses on. I may try taking them off if I try to film myself, but I'm not good at hooping to the camera anyway so it rarely works. Hooping with your eyes shut or blindfolded is I think very different to having substandard vision.

I realised today the I need new glasses anyway because I can't read small print very well now. So perhaps I'll try to be good and keep the old pair for hooping in just in case.

Nicki dear, I totally understand the glasses/no glasses thing. I am so freaking blind that not having my contacts in is disorienting enough without spinning and hooping. It's very different from hooping blind, and not in a good way. I would suggest taking off your glasses and then putting on a blindfold so that you just get the blind effect, rather than the blurry effect, as much as possible. I know this isn't always possible though, so the next question is what is more important - not breaking your glasses or not having the blindspots/bumping your glasses and interrupting your flow? If you are more concerned with not breaking your glasses, I'd say get some safety goggles with an elastic strap that can fit comfortably over your glasses. Dorky, I know, but glasses are expensive and it sucks when you are waiting to get them fixed!

When did you try wearing contacts? I have been wearing contacts for 20 years (they started me early because my eyes were so bad) and there have been a lot of innovations in the last few years. I've had some contacts that really bothered my eyes and felt terrible, but if you try some of the new soft disposable lenses, you might like them once you get used to sticking your finger so close to your eye. Your eye doctor should be able to give you a sample pair for free that you can wear for a few weeks so you have time to adjust to them and decide if you like them. I think the ones I have now are Oasis Accuvue. I wear each pair for a month so I only need to buy four boxes of contacts per year and they cost about $25/box when I buy them from my optometrist. You can probably get them for less if you go to those 1-800-CONTACTS places though. These contacts are awesome. You can even sleep in them if you want (although you shouldn't sleep in them for a month straight). It answers that age old near sighted question: "What would it be like to wake up and be able to see?"

I'm waiting for the day that something more advanced than laser surgery comes along (and is affordable!) because my eyes are so bad that even if I got corrective surgery, I'd still have to wear glasses or contacts. I know - I'm like Mr. Magoo!

I've broken at least one pair of glasses while hooping, but like you, am unwilling/unable to wear contacts.
If I'm not hooping blindfolded, then I just wear my glasses. It stinks, and is a risk of damage, but it beats the headaches/nausea I suffer when I'm not wearing them.

I'm waiting to hear more about the surgically implanted contact lenses. They were approved in the E.U. and are being clinically tested here.
They're little lenses that are slipped into an incision in the cornea. What is nice is that if they don't work out, they can be removed (unlike Lasik).
As long as no infection damaged the corneas, the procedure is completely reversible.
