I am a long time spectacle wearer with quite a high prescritoin lense. In the past when I was a young carefree shagger I had soft contact lenses that I took out every night and cleaned just like false teef. they weren't disposable and lasted until one took a trip down the plughole. I'm looking at lenses now and have been told that with my prescription I will need toric lenses. What I need to know is do the monthly disposables vanish after a month or can they be used for longer, and what about daily ones, are they made of different material ? Any pointers and good deals appreciated, I do a lot of running and underwater ninja knife fighting so it would be nice to lse my specs. So to speak.
