i have been wearing hard lenses since I was 11 years old (I'm now 29). They were chosen for me as the best possible type of lenses by my Optician. Hard lenses can apparently help to slow down your deterioration of sight - and mine was deteriorating at an alarming rate! When I first got my lenses there was a choice between Hard and Soft lenses only. There is far more choice on the market now, disposasbles (monthly, daily etc) hard, Soft, gas permeable etc. so why do I stick to my Hard lenses, especially when Opticians now often do not stock them. Firstly, I'm comfortable with them. The do what they are supposed to do - help me see. I am not dis-satisifed with them, so why change? Secondly, cost. The products which are required to keep other types of lenses clean and ready for use are *far* more expensive. Disposable lenses are probably the most expensive of the lot, and I hate the idea of being wasteful and throwing things away, so they are not for me. the only other type of lens that i would consider is gas permeable, which I understand is the closest to hard Lenses. However when I asked my Optician what were the advantages of GP or Hard lenses, he could not give me an answer. Until someone can give me a solid definite advantage, I'll stick to what I know. if it ain't broke don't fix it!
