I could give an amateur response, but why don't you just go to your local opticians and seek advice through them? A more professional response from individuals with greater understanding. I'm pretty sure somewhere like Specsavers can conjure up an alternative for your situation. From my knowledge you can get contact lens' either in the form of dailies which you would chuck away every day and then there's monthlies. Again make an appointment and they will find which is best based on your life style.
