Normally, your optician will give you a trial pair of contact lenses to try out, and then check them for fit once they have settled in your eyes. Sometimes, you may need to try out several different pairs before you find the perfect fit. The lens you choose should give you better vision, fit comfortably in your eye, and not do any damage to the cornea. Although contact lenses are great to wear if you need vision corrections, there are some things you should know. Before you put your contact lenses in your eyes, you should always inspect them for tears or defects. Sometimes, contact lenses can get tears in their material, resulting in serious problems if you put them in your eyes. Contacts however, don t fog up. You can carry out any activity you choose without having to worry about them all. They won t fall off or slide down your nose when you run, nor will they limit what you can do when you play sports. Another bad thing about glasses is the fact they need to match what you wear. If you are looking to change colors on a frequent basis, disposable lenses may be your best choice. The best thing about disposable lenses is the fact that you don t need to clean them at all, simply wear them during the day then take them out and discard them at night. If you are going to use the same color or the same pair of contacts for a while, you may want to go with daily wear lenses. If you are ordering them online, you ll find hundreds and hundreds of different colors and images. There are more colors and selections available online - making it the best way to invest in your contact lenses. If you ve been thinking about adding some flair to your contacts, you should look into getting a pair of colored lenses. Dry eyes are the most common reason for irritation, and the main reason as to why people decide to give up contacts and just go with glasses to correct their vision. Out of all the different contacts on the market, Acuvue Oasys are among the most popular. Although they are relatively new, they are specifically made for those who work or live in dry environments.
