Throughout the day, you may need to use rewetting drops or saline solution to keep moisture in your eyes. Sometimes, contacts can dry your eyes out, and make them feel very uncomfortable. When you put some drops or saline in them though, the dryness will normally subside. You should always keep some rewetting drops or saline with you at times, just in case your eyes start to dry out. Daily cleaner solution Daily cleaner is used to clean your contacts. Simply place a few drops of the cleaner in the center of your hand and then rub the lens gently in the solution.

Even though cheap lenses are praised by some - others don t look at them that way. Some feel that cheaper lenses should be avoided at all cost, for the fear that they may damage vision or not offer the same quality that the higher priced brands of contacts offer.

Contacts are divided into two main groups - soft and rigid (hard). Soft lenses are gas permeable to a certain extent, being further categorized by the amount of water they contain. Soft contacts can have either a low, which is less than 50 percent moisture, or a high moisture content, which is more than 50 percent. Contact lenses on the other hand offer you a great field of vision, including peripheral. You won t be hindered to just looking straight ahead, as contact lenses allow you to look anywhere you want without any problems. Another major difference is the weight. Glasses are uncomfortable weight on both your ears and your face.
