What are disadvantages of purchasing cheap contact lenses without prescriptions?

Answer 1

Advantages: * Glasses get annoying because you can't use your peripheral vision but with contacts you can see everywhere * You don't have to worry about your vision being obscured by dirty glasses * If you play sports contacts are much safer because glasses can break and injure your eyes * With contacts it's much less of a hassle doing daily activities because you don't have to worry about your glasses Disadvantages: * When you get tired your eyes start to feel really dry and they make you more tired * If you don't clean your contacts properly you can develop eye problems * It's sometimes annoying to have to bring around your contact case and liquid when you're not going to be coming home for the night Hope that helps =) As a side note, hard contact lenses are healthier for your eyes because they are smaller and allow your eye to get more oxygen but are more of a hassle in the beginning because they take a few months to get used to and are very irritating at first. They are not good for sports. Otherwise soft lenses are the way to go.
