Although it is possible to wear your contacts past their replacement date, it is not recommended. Doing so can cause irritation or infections. The one major difference between the two lenses is that RGP contacts allow oxygen to penetrate through to the eye, while PMMA contacts do not. Because of this and the fact that these lenses are so durable, bad habits with respect to the daily maintenance routine can lead to eye health issues.
Disposable contacts are just like any other disposable hygiene or medical product. You use them on a short-term basis and throw them away after the recommended time period is up. The lifespan of disposable lenses will vary from brand to brand, but they can last for up to a month. In general, it's fairly easy to care for contact lenses. Lens wearers float their lenses in contact solution when not wearing them.
The solution usually has a preservative, buffer, binding agent, and surfactant. These all work together to disinfect your lenses and remove buildup. Most also suggest that you gently massage the lenses in solution prior to storing them.
This helps prevent buildup of bacteria and ensures your lenses stay fresh overnight. Be sure to have a conversation with your eye doctor about the best steps to take for a successful contact lens care routine.
Most people who require any vision correction are good candidates for contact lenses. You should never wear a lens that has expired. Contact lens solution is often an overlooked aspect of contacts, but there are a couple of things every contact lens wearer should know. First, you should never leave a lens soaking in solution for more than a week. If your lenses have been soaking for more than a few days, replace your solution with a fresh amount the night before you plan to wear your contacts.
On top of that, regularly changing your solution is key for optimal eye health. Monthly contact lens wearers should expect to use roughly 9 bottles of solution a year. Maintaining a regular schedule of swapping out contact lens solution is vital for keeping your contacts in their best condition.
Keeping those lenses clear of any proteins or particles will guarantee happy, healthy peepers. Another often overlooked aspect of contact lens care is your lens case. Did you know you should be replacing your lens case every three months? Colored, costume, decorative, and cosmetic contacts have to follow all the same rules and regulations as those worn to correct vision disorders.
Any contact lens that goes on your eye is a medical device and should be handled with caution to prevent eye infections that can lead to vision loss. As a general rule, the more time you give your eyes to rest and breathe without contacts on, the healthier your eyes will be.
I like Alcon solution. I wear 2 week Focus disposables. I can wear them for almost a month before they start feeling gross. I like the ReNu brand of contact solutions. I think the one I have is called "fresh" or something equally lame. I can't imagine a 2 week or even month pair being any different whether it is a trial pair or not. Laser eye surgery is amazing. I don't miss doing all of this crap. If you can swing it I highly recommend it.
I was wondering about this too. I am also currently wearing a trial pair of lenses. My conspiracy theory tendencies are telling me that they probably won't last as long I was originally told, by America's Best, to wear my disposables for as long as they were comfortable This is normal and actually encouraged. The whole point of trial lenses is to ensure that you get the best pair of contacts for your eyes, after all. In most cases, you can use your trial lenses exactly as you would use your more permanent ones.
If this is your first time using contact lenses, be sure to tell your doctor and have them go over the dos and don'ts of contact lens use and how to care for them properly. Sleeping in contact lenses is generally not a good idea. Your eyes need a constant supply of oxygen. Contact lenses get in the way of the natural exchange of oxygen that occurs through your cornea.
When you wear contact lenses all day, it's important for your eyes to get a break at night. Not to mention, with your eyes closed, there's already less oxygen entering your eye.
Wearing contact lenses while you're asleep only makes it worse. Over time, an oxygen-deprived eye can start to develop problems. First of all, the eye will become bloodshot. This is due to the blood vessels expanding in an effort to absorb more oxygen.
Eventually, this oxygen-deprived state can lead to serious eye diseases like macular degeneration. Of course, if you sleep in trial lenses for the short period of time that you wear them, you probably won't see these issues.
