I have mono-vision contacts...one for near, one for distance. Since my eyes were naturally one much more near-sighted than the other, this has worked fine for me. I had single vision contacts initially when I was in HS up until I needed bifocals. Tried the bifocal contacts, but they were not available in the right combination to work well for me. So have had the mono-vision for the past several years. Not everyone likes the mono-vision solution, but it works for me.
