I'm interested to read that any optician would think this is a good idea. I have one long sighted eye and one short sighted eye. I have trouble getting them to focus together, and although I can read with one eye without the aid of glasses, and don't wear glasses just to walk around, I need them to use the computer as I can't see it without, and I can't drive at night without. Opticians have tried to get me to have one contact lens, for the short sighted eye, but this would mean reading glasses as well as spares in case there was a problem with the lens and would work out costing more than two pairs of glasses. But from what the opticians tell me, they think it is bad to have eyes that see differently, which is why it surprises me that they would offer this as an option.
