So my mother finally agreed to getting me colored contact lenses but my eyes have an astigmatism so they're hard to come by. I've found some toric (lenses made for astigmatism correction) so i entered my prescription information. The highest (lowest?) power (SPH) they had was -4 and I have a SPH of -5 on my lenses.
I was wondering if I could leave the power at -4 since A. The contacts i have now should have made my eyesight better or B. If the eyesight in that eye is bearable I'd still wear them. What should I do? Leae any suggestion or your opinion if you don't know please:)
