If generic disposable toric contact lenses for astigmatism are not for you, and you prefer custom-made conventional lenses instead, Optima Toric lenses are one of the best choices available. These Bausch & Lomb lenses are intended for daily wear and can last up to a year with proper care.
There are many reasons why you might choose conventional lenses over disposable ones. Perhaps you need a custom solution that cannot be addressed by ordinary brands. Maybe you object to the idea of throwing away something that could be re-used because you believe that doing so damages the environment. Maybe you have special medical needs that can only be addressed by conventional lenses. Whatever the reason may be, there is no need for you to feel like you have to put up with an inferior product compared with people who wear disposable lenses.
Optima Toric contact lenses are prism-ballasted eye contacts that are manufactured using patented lathe-cutting technology. They are made to last and can be ordered in a wide variety of prescriptions.
Bausch & Lomb uses a polymer called hefilcon B for making these lenses. It is a sturdy substance built to last instead of wearing down easily as do most disposable lenses. This polymer absorbs water when undergoing the nightly cleaning cycle, filling up to 45% of itself with water that helps the lenses feel silky smooth while you wear them during the day.
Disposable lenses that are replaced frequently have easy requirements for lens care, and can sometimes be worn for days at a time. Requirements are more strict for lenses that are going to be used for several months at a time. Lenses used for so long make deposit buildups and bacteria a problem that must be correctly managed to maintain good eye health and keep your lenses feeling great. There are a variety of different chemicals, enzymes, and heating methods available on the market that will help keep bacteria away and your lenses free of protein and lipid buildup. Your eye doctor will recommend the ideal cleaning method and schedule for you based on your individual needs.
When you have astigmatism, it means that your eye is not shaped like most others. It is more like an oval or egg rather than the perfect sphere it should be. That’s bad news because it causes light rays to scatter and bounce around instead of focusing correctly on the retina, which then leads to blurry vision. Optima Toric lenses reverse the problem by sitting atop the cornea and acting like a prism that bends light back to the retina where it belongs. The result you see is 20/20 vision once again.
Since the lenses act as a prism, they need to be placed just right in order for them to do their job. That means that the heavier part of the lens must go towards the bottom. It’s not always an easy task to figure out what the heavier part is, since the lenses are so thin to begin with. Optima Toric lenses come with three little etchings at the bottom of each lens to help you out, guiding you as to how exactly you should put each lens in your eye.
These lenses are built to last, but for just how long? Your eye doctor is the best person to advise you on that. It will ultimately depend on how you use the lenses, the cleaning method, and other factors like individual medical needs. Following your doctor’s advice ensures the lenses will continue to feel fresh and will not overstay their welcome.
If you’re looking for a set of custom-fitted lenses for astigmatism that will last a long time without having to throw them away, then ask your doctor about Optima Toric lenses. They are sturdy and specifically made to last months if you treat them well.
