Why do I need to change my contact lenses?

You can buy single lens cases and you should change them frequently just because of the bacteria build-up and you are putting the lenses in your eyes after they soak in these containers.  Your eyes need oxygen and need to breathe so take them out every nite and clean them, even if they can be left in for 2 weeks at a time, it is just a good habit to keep em clean.

It's not an economic ploy.  The material that they make 2 week contacts out of really isn't designed to last much longer than that.  A lot of it depends on your individual tear chemistry and eye health as well.  Some people are able to wear 2 week lenses for 3 or even 4 weeks, but only under the direction and supervision of their eye doctor.

I've worn hard contact lenses since Adam was a boy and with no problems at all. Contrary to what others may say, they are not difficult to put in (your eyes), it just takes a little practice. Of course proper hygiene is necessary (wash your hands before you put them in or take them out, clean them daily and store them in fresh solution). See an eye care specialist and don't buy cheap lenses.

I'm nearsighted and wear glasses at work.  When I usually meet people for the first time (or going to a party or club), I wear contact lenses because I want people to remember my fact, rather than my glasses.  Besides, people who saw me wearing glasses first will think something is missing when I don't wear glasses.

well the doctor is probably going to make a regular check up on your eyes to make sure they are ok and everything, and then he/she determines the size of your contact depending on the size of your iris...so then you try on a pair and he checks to see if they are the correct fit (my doctor uses this machine thing that gets really close to your eye, im not sure what it does exactly) and then the doctor or something else teaches you how to take care of the contacts and put them into your eye...

# Can I swim with my contact lenses in?\nIt is best if you don't because there are bacteria in the water that can adhere to your lenses and cause infections. If you do swim in your lenses, you should wear goggles over them and you should disinfect them immediately afterwards.

How long have you been wearing your current lenses?  Have you been disinfecting them properly (as your doctor instructed you)?  Are you using a different brand of contact lens solution?  Sometimes you can develop a sensitivity to a solution after you've used it for an extended period of time.  Consult an eye doctor (optometrist or ophthalmologist) you trust for more specific answers to your questions.

If I remember correctly, the contacts that were recalled were the weird cosmetic ones that, for whatever reason, didn't require a prescription... they were the ones that had things like swirls and cats-eyes.\n\nTinted lenses from a big-name company that you buy from your optometrist are probably going to be fine.

Wearing contact helps - coz ur center does not change - and has more sharp / focus than glasses.\nIf u follow eye related healthy diet/exercise - u can get by with a smaller no, like  -1.75 for starter, and help it reduce further (coz ur eye will not suffer strain from change of optical centers, etc - as is with glasses...\nTheoretically, one cannot go beyond 20/20, it is perfect vision...

It is not good to over wear your contacts, but, if you do as long as your eyes are not irritated and/or turning red you will be alright. Just keep a watch on them and change them as soon as possible.If they start to turn red or a milky looking film comes from your eyes you may have an infection in your eyes have this checked at once.

Actually, they're more similar than you might think.  Any contact lens has to be prescribed by an eye doctor because contacts are technically medical devices.  Contacts come in many different sizes and fits, so your eye doctor has to select a lens that fits your eye properly and lets enough oxygen through.  If your contacts don't fit you correctly, serious damage to your eyes can occur.  What you mean by cosmetic contacts is probably colored contacts that don't have any power (prescription) in them.  These can be fit and prescribed by your eye doctor as well.

If they are the same prescription they will work the same, but you see differently out of each, just give your eyes about a minute to adjust from one to the other.  ]\n\nI used to wear glasses, but I have wore contacts for about ten years now.  I don't like wearing my glasses anymore...only before bed-time!

yes, depends on the manufacturer. You can get weekly,by-weekly, monthly and yearly contact lenses. Refer to your optician.

Depending on each person, if you wear a lot eye contact lenses that could lead you to some eye-illnes, like infections.\n\nThere are also many people that looks better with spectacles, so it could be also a good reason.

Well it could be many reasons.\n1. You're not used to your lenses yet. It takes between 1-2 weeks for you to adjust. Moisturizing eye drops might help you get used to the lenses.\n2. You're wearing your contacts the wrong way around. Your lens should look like a perfect concave bowl resting on your finger.\n3. You might not wearing the right size or "roundness". You can rule this out if you feel ok in a week. If it's still uncomfortable, you might want to get refitted.\n\nHope this helps. If your eyes go really red and you start tearing, you should remove your lenses and get checked.
