So I had an eye exam today and the prescription they gave me is far less than my last. I'm used to getting a stronger prescription everytime I get new contacts. My old prescription was -4/-3.5 for L/R and now they gave me somethign like -2.75/-2.5. Is this weird or fine? I'm trying to figure out whether I really can't see as much or whether I'm just paranoid. I've tried putting old lenses in but I'm not sure.
