Protein and fat build up on soft lenses after a period of time. If you notice your contact lenses become uncomfortable after a certain amount of wear it means it is time to change your lenses. If you find you are changing your lenses too often talk to your eye care professional about changing your lenses, your wear schedule or your cleaning solution.
There are 3 basic types of contact lens materials: hard lenses, gas permeable lenses and soft lenses. Hard contact lenses are specailty lenses that are hardly ever prescribed today. Gas permeable contact lenses are small, rigid contacts that are excellent for individuals with astigmatism or very high prescriptions. Soft lenses, the most commonly prescribed lens, are flexible and generally the most comfortable type of lens for new contact lens wearers.
Individuals who do not remove their lenses every night are at a great risk for complications such as eye infections. To reduce the risk of complications consider removing your lenses for a shot time every day or every few days and soaking them in a multipurpose cleaning solution.
If you plan to go camping, take a long trip or have an adventure planned ask your doctor about daily disposable lenses. Typically sold in packs of 30 lenses, these contacts require no cleaning and are thrown out after each use. They are wonderful for a trip or excursion where you may not have the ability to maintain your regular contact lens hygiene.
