Question regarding two-week disposable toric contact lenses??
Question: Is that assuming I wear them at least 12 hours a day, every day, or can they be stretched into three or four weeks if sometimes I don't wear them at all in a day, i.e., a lazy weekend where I stay home?
Answers: First off,the fact that you have a toric lens you face a greater chance of problems stemming from contacts so I wouldn't push the time limit on any contacts that you might wear.
Trying to keep up with how long you have worn a pair would be next to impossible and with that in mind you could be wearing those contacts way beyond the allowed period of time.
There is going to be a certain amount of protein build up on contacts regardless of how well you take care of them and to push a pair of contacts beyond the recommended period of time is asking for corneal problems and as a toric patient you can't afford these kinds of problems.
Wear your contacts as prescribed and don't alter this. . . it is in the best interest of your cornea.
a two week contact lens is made for roughly 12-14 hours a day for two week of total wearing time, so if you only wear them on the weekends, they can last for months! this is healthy, just don't abuse it...once they have been in your eyes for 14 different days, toss them. even if they were only in for a few hours that day.
They can usually be stretched a bit beyond the two weeks if you don't wear them every day and are using a better quality, peroxide based cleaning solution. There are protein-removing enzyme cleaners out there, too. Ciba Vision's Pure Eyes and Aosept systems are good ones, as is Ultracare's. Keep in mind that these are more expensive systems and involve more steps - that has to be weighed against the money saved by extending your contact lens disposal schedule (if $$ is even the issue - some ppl just don't like to waste things they don't have to). Some of the contacts that doctors prescibe as two-week disposables are approve for up to one month of wear with proper care, cleaning, and wearing schedule. You can check with the manufacturer or with the FDA on what the approved schedule is for disposal. Note that most boxes will say for two weeks or as recommended by your eye care professional - that is a safety net and a money maker for the optical. Two week disposal means double the $$ for the optical and the manufacturer, of course. Keep in mind that these lenses were originally designed as a solution to patients who have a lot of protein build-up, abused their contacts (overwearing, not cleaning properly, etc.) - and as a way to keep the $$ flowing.
12 hours a day max would be good, but don't keep the same lenses for more than two weeks. They were made that way for a reason after you start wearing them they can develop protein buildup and the material of the lens is desgined to only last so long, it starts to break down and your vision can decrease slightly, not to mention the health of your eye problems you can get by overwearing certain kinds of lenses and or length. Listen to your eye doctor and the manufacturer of the kind you wear. It is not fun to get corneal ulcers or eye infections from overwear or lenses that are dirty!
