PMMA

Product Information for PMMA

Soft contact lenses have become all the rage in recent years, but they certainly have their challenges, not the least of which is fragility. The softer the lenses are, the more difficult they become to handle, which means that they don’t last long and can be incredibly frustrating to deal with. For those who want to avoid the hassle of fiddling with flimsy lenses there are still hard contact lenses on the market and they’re not like the hard contacts of the past. PMMA contact lenses by Optical Polymer Research are well respected in the contact lens world as they have been around for a long time. That longevity means these lenses have a ton of research behind them.

Unlike the original hard lenses, the current PMMA lens is permeable, allowing high levels of oxygen to pass through the lenses and get to the cornea. Amazingly, these modern day hard contact lenses allow more oxygen to pass through them than traditional soft contacts. Oxygen transmission is important because it is necessary to keep eyes healthy and clear. Manufactured from polymethyl methacrylate, or PMMA for short, this material is highly durable and particularly useful in creating lenses that are stable on the eye. Additionally, soft lenses contain water, which increases the likelihood of bacteria building up on lenses and causing an infection. Made from 100 percent polymer (alphafilcon A) PMMA contacts are strong, stable, and breathable and promote eye health. Despite not having any water content themselves, PMMA contacts are very wettable.

Since these lenses are so resilient, there’s no need to replace them as often as you would with soft contact lenses. To keep eyes in optimal health, PMMA contact lenses need to be removed, cleaned, and stored at the end of each day. After a year’s worth of daily wear, PMMA contacts should be replaced. As with other types of contact lenses, it’s best to stick with your eye doctor’s recommended replacement schedule, as it may differ from the replacement schedule that’s recommended by the manufacturer.

As these are gas permeable contact lenses, each PMMA lens is custom created to your specific prescription. This means that PMMA contacts provide exactly what your eyes require for clear vision. Even better, with such an infrequent replacement schedule, wearing PMMA contacts can be a big money saver and, when you shop with Lens.com, you can save even more money.
