Well maybe you just don't have the right kind of contact lenses. There are two way you can buy contacts. One just get the ones most people uses or you can get the expensive good kind thats right for you. Last time I went my doctor and said I want one that gives me the best vision and doesn't irritate/dry my eyes and I can wear it for a long time. He than gave me this cotacts that cost about $500 for a year. Believe me once you wear those you will be glad you got it. You will for sure be able to tell the difference. Another things you might wanna mention to you doctor that you want the best vision possible. The contacts I use gives me 20/10 vision which is the best you can have as a human. If you want more info about call (254-766-2282)this number and ask for Dr. Gerdes. You don't have to go to him, but he can tell you what you need. He is a pilot too, so knows a pilots need real good. So my suggestion to you would that you might just wanna figure out exactly which type of contacts you need rathet than just a generic one for everybody.
