If a contact is used throughout the duration of a day, then it can cause unnecessary stress on your eye. Every contact user probably has experienced this discomfort themselves at one point in time or another. Beyond them possibly causing your eyes to get irritated or dry from prolonged use, however, are there any consequences for using them longer than their recommend life-span? And, in all actuality, how long are contact lenses really supposed to last? A day? A week? A month? Maybe even longer, if you are really trying to stretch them out and make the most of your money?
Contacts usually come with a recommend period of use. Some of them are to be used daily, while others are supposed to last for a longer period, usually around a month or so. How long you can extend their use can depend upon many factors. For example, the quality of the contact lenses themselves or the sensitivity of an individual’s eye. These are things to keep in mind when you are dealing with your own contact lenses. Know how you react to prolonged use and see if you have adverse reactions or side effects due to using them longer than the suggested time period. If you do, then you may want to change them closer to the recommend time.
But why should the period even matter? Are there any adverse reactions you may suffer because of a prolonged usage of expired contact lenses? The answer is yes, there is.
If you use a pair of contact lenses for longer than the suggested time, then there can be some adverse effects on your health. For instance, some contact lenses are made of material that makes it difficult for oxygen to get through and reach your eye. This can dry the eye out and cause irritation. If you wish to sleep with contacts in, or use them for a longer period of time, try to purchase contacts that are specifically designed to allow more oxygen to pass through.
Another consideration for when you use contacts for longer than there recommend time is that some contacts are comprised of material that are more prone to collecting debris. This debris can be deposits of normal components of tears, such as lipids or proteins. If this kind of build-up occurs, then infection or other types or irritants may occur. Other forms of debris can also occur, such as dirt getting stuck on the contact lens and irritating your eye as a cause.
