With so many users using contact lenses these days, it is amazing how many users still have very little idea on how to maintain their lenses in optimal form. Many of the users go out for a night in town, only to return and handle their lenses before washing their hands. Hygiene is the number one most important rule when it comes to handling your lenses. Without properly washing your hands, invisible dirt can easily find itself stuck onto the lens without you noticing. The only real way to prevent this is to thoroughly wash your hands with soap before even touching your lenses.
Secondly, storage of the lenses is also an important factor. Are you using the right saline solution to store your lenses, or are you using one that is not compatible? It is easy to know if the solution for your lens is not compatible. It will sting when you place the lens in your eyes. Contact lenses should never sting when placed in the eye. They should sit comfortably upon insertion, and remain comfortable for the whole day. Also make sure you replace your lens case once every 3 months, since bacteria can easily form on the edges and areas where there is more handling. Give your case a good rinse in warm water every week, just to kill any bacteria and germs. There is nothing worse than getting an infection of the eye, since then you will have to go through a course of antibiotics.
Finally, be wary of any dust or dirt while you are out. If you are in a windy area, bring a pair of sun glasses along with you. This will protect your eyes, and also your lens from any abrasive dirt which can easily get lodged in between the lens and your eye. This can become very uncomfortable and even cause minor damage if it continually scratches your cornea. If you must remove it, then do so indoors, and again wash your hands thoroughly. Never use saliva to lubricate your lenses, since your saliva will most likely be contaminated with germs from your tongue as well. Bring a small dose of saline solution, which can be purchased from the chemist in small takeaway packs.
