I'm a fairly new contact lens wearer and I trusted my optometrist with everything - he bought for me a certain brand name of lenses - a year's supply was about $150 which is really expensive for me. However, my year's supply is running down and I'm gonna come back next week for a checkup to update persecriptions, but I don't want to buy the lens through him since it seems expensive. So do I just have him recommend a certain brand and have him give me my perscriptions so I can go to this website and buy it? Or can I just find out my perscriptions and buy whatever brands I want? Since I don't know the process of finding the right brand and selecting the right perscriptions, can someone explain it to me? Thanks.
