How long do contact lenses last for?
A single contact lens can be permanent, or last for a couple of weeks, or a month, or be designed to be worn for one day only. It depends on what type the doctor prescribes for you. In all cases, daily care and cleaning are necessary. There are special solutions for cleaning and storing lenses. You keep them in a little case that has one compartment for each lens. When you get your lenses, the doctor or staff will show you how to put them in, take them out, and how to clean and store them. If you are a swimmer, you can usually wear your contacts at practice if you put your goggles right on over them. It's actually great because you can see your times!
Contact lenses solution: how many times?
When you put your contacts in your eyes, dump out the solution from your case. If there's any debris in the case, rinse it out with solution. Let the case air dry during the day. Rinse the case out with solution and put new solution in the case when you take your contacts out of your eyes. Make sure to rub the contacts before you store them. If you put in/take out your contacts more than once a day, I would do this each time you insert and remove. It's the best way to keep everything clean. Some other reminders: -Always wash your hands before touching your eye or your contacts. -Never use tap water on your contacts or your case. -Contacts cases should be replaced every three months. -Don't overwear your contacts (by sleeping in them if you shouldn't or by wearing two-week contacts for a month for example). It is dangerous for your eyes. Congrats on getting contacts and enjoy them! :)
How many times can I wear my contact lenses?
As another optician has pointed out, there isn't a weekly contact. But, if you are just using that time frame as an example, as you have said, then I can answer your question. Basically, the lens material while in use will start to degrade, and after it gets much past the recommended time frame, it has horrible effects on the eye. For example, I had a patient that she wore a bi-weekly contact for 2 months straight, without taking it out once. The contact lens had fused with her eye, and when she pulled the contact lens out, she pulled out a small layer of her eye with it. YIKES! But, to answer your question precisely, it goes by how many times you wear it. A 2 week contact will last around 14 days of use, so if you only wear it one week, and keep it hydrated in solution for another week, then you can still wear it another week as the material hasn't degraded (a little, if anything). Just keep an eye (pun intended), on the solution it is in. If it evaporated, and the soft contact lens is in the container without hydration from a solution, it will be unwearable.
What happens if you use the contact lens solution for longer than 3 months?
Did you mean to say the same solution on lens case using it for three months,then it's not good for both of your lens and eyes when you use it.the solution has the ability to disinfect the lens for limit amount of time(few days only) so if you it for long then you know what will happen,if you don't know then, here's what it will happen,first your solution starts to get weak on ability to disinfect the lens slowly the amount bacteria will increase on the lens,and if you throw it, it's Okay,but if you where it then there's higher chance that it'll infect your eyes and cause serious problems in your eyes..Better be safe now than feel sorry later!!
How many time can you wear disposible contact lenses?
Acuvue2 are 2 week disposable lenses... If you are wearing them 2-3 times a week, then as long as you are changing the solution every few days, you should be able to wear them for 14 insertions and 14 removals. So if you do the math, that would mean about 7 weeks, if that's all you wear them. The key is keeping the solution fresh in the case. Don't let them soak in the same solution for days and weeks on end because that allows bacteria to grow. if you change the solution in the case every 3 days or so, you should be fine.
Should I wear my contact lenses during an 8 hour long flight?
Seeing as on an eight hour long flight, you'll probably be doing nothing except watching TV and sleeping, glasses should suffice. The aircraft's dry air combined with wearing contact lenses may create an uncomfortable situation. Thus, the easiest thing to do is to wear glasses during the flight, and once you're on the ground and it actually matters how you look, put in contacts.
Can I wear two pairs of contact lenses at the same time?
I think the correct question is whether you should or not!Let me tell you.We have an awesome customer that buys coloured lenses every month, sometimes twice or three time in a month (that’s strange :) )Because he wears prescription lenses, sometimes he finds a colour that he likes but doesn’t come in powers.One day, he sent me some photo via facebook, just because we’ve developed some friendly relationship, to tell me that the lenses colour was awesome, and that he solved the power problem, by wearing the prescription lenses above the coloured!No matter how many times I advices him not to do, fortunately, more that 1 and a half year later, he is still doing fine and had no problem so far.So, should you do it? NO.If there is reason, talk to your optician.
Is it bad to use daily contact lenses for more than one day?
First I am going take off the Dr. hat and talk as a consumer. It has been admitted to me (by some forgotten source) that their new daily wears were the same as the monthly wear. Monthly wear were to be taken out nightly and disinfected. If one wanted to risk their vision and ocular health by using the daily wear lenses for several days (removing and disinfecting at night) Mars would probably not fall out of its orbit. Leaving them in as extended wear for several days is counter to the purpose of the lenses and could present the eye with increased risk of infection or other forms of inflammation.With the Dr. hat back on, people have become much too casual about contact lens wear. We definitely do not recommend leaving them in overnight. Each time they are taken out as directed to be used again, they should not just be rinsed with saline, but put through a disinfection cycle before being replaced in the eye. Yes, millions of people mistreat these instructions and do ok for a while. But contacts are not like wearing a pair of sox. The contact changes the O2 content, tear film, microbiology, and mechanical forces on the cornea. When you have seen an eye destroyed (no vision) by improper contact lens wear, you become much more inclined to save that one in a thousand from having any problems in the first place.This discussion is of general recommended practices, and does not constitute medical advice to any individual.
I haven't used my contact lenses for months nor changed the solution. Is it okay to use them now?
Most MPDS solutions allows safe storage and disinfection ONLY up to 30days. Beyond that DO NOT wear lenses as they will be contaminated.Generally what I've always recommended is change the solution every few days to about once a week eventhough lenses are worn infrequently. This way there is no chance of contamination. If you change the solution frequently they can be stored indefinitely. Make sure you are using a high quality clean lens case that seals well. It's only safe to store lenses longterm in a leak proof case. Seal titghly during storage.I only ever wear my colored lenses once or twice every two months or so and they last me about 6-8months.
What are the health concerns in reusing daily contact lenses?
It’s the same stuff. The major companies lost a lawsuit trying to keep this information proprietary because they were ripping off consumers with false claims. The daily hydrogel soft contacts are just thinner, more breathable, and therefore more fragile than the longer-use ones. Some of the materials used may retain moisture less because they are less thick. Probably the more annoying aspect, until you get half of one stuck up under your eyelid, is sometimes the difficulty in telling if they are inside out or not compared to thicker lenses. If you clean, disinfect, and remove protein from them every day, they can hypothetically be used as long as extended wear versions, aside from their tendency to rip easier. The most important part of any of them is to clean them properly every night (don’t just stick them back in the blister pack and old saline they came in), don’t sleep with them, go to the eye doctor every year or even more frequently if you are having discomfort or vision problems, and don’t wear the same pair for months. The last one is something I learned the hard way: even with the best care regime (and I did EVERYTHING), eventually the lens pores on even extended wear ones will fill with deposits, even if they are completely sterile. The permeability of the lenses therefore decline over time, which can cause blood vessels to grow into the back of the eye where they don’t belong in an attempt to oxygenate the eye in the absence of enough oxygen coming through the front through the ambient air. Also, it is worth noting that dailies are so cheap now (less than 25 bucks for 90?) and cleaning solutions are not dropping in price, that between the zero risk of just throwing them out and the slight risk of rips or contamination using them a few extra times and extensively cleaning them after each use, there is not a whole lot of incentive to reuse them unless you have a lot of cleaning solutions on hand already and have previously demonstrated you can do that safely. If you are new to contact lenses or you don't have a lot of solution already on hand, I don't recommend reusing dailies. You are better off spending that time finding them at the lowest price you can from reputable vendors. FYI don't forget the diameter and associated characteristics not part of the prescription.
