One eye specialist prescribed me below power: Right +0.50 sph, -1.75 cyl, 180 Left +0,25 sph, -0.50 cyl, 120 Another eye specialist prescribed me below power: Right 0 sph, -1.25 cyl, 180 Left 0 sph, -0.50 cyl 130 Both are clear to me. My only question, which power should i go for now as i dont want any headache or eye strain. Please advise. Thanks
