In reply to ow arm:
Sorry, but I WAS trying to be constructive. If you've been wearing specs since you were 6, and no optician has mentioned rx goggles, then you've been going to the wrong optician. End of.
It really p*sses me of how much good stuff there is out there - different types of contact lenses, ortho k, swim goggles, prescription sunglasses etc etc and so few people seem to know about them. And the chains - Boots, Specsavers, Asda etc have no interest in discussing them because it does not fit their business model, which is to flog specs as quickly and simply as possible.
And as I say, your vision will change in a few years time, so you will have a whole new set of issues to deal with - it's called presbyopia, check it out. Then you really will benefit from having a decent relationship with an optician who is able to take the time to discus the options available to you.
