before you can wear contacts , it is necessary for you to visit your doctor not Wal-Mart or Pearl or Lenscrafters. and have an eye exam .the doctor will measure your eyes, and decide on what contact lenses are best for you. When you get the prescription , you can take it to lenscrafters or walmalt to order the contacts you need .
It is much easier to choose contact lenses than eyeglasses. Just taking a eye test to get your prescription. Then use your prescription to buy contact lenses from some glasses shop or order it online. If you have no special requirements, common clear prescription contact lenses can meet you. If you also want to look good, you can also choose colored prescription lenses according to your preference on eye color. By the way, if you want to buy it online, you can have a look at 1800contacts.com or coastal.com etc. Hope this can help you.
I would go to my eye doctor so he could tell me where to buy lenses. I think this is the only logical thing to do. My friend at https://domyhomeworkfor.me/math-homework-help had bought lenses without any prescription and recommendation from his doctor and those lenses turned out to be the worst for him.
