Modern contact lenses are comfy, lasting (unless by design, as in disposables) and very safe. Yet, there are some risks and limitations in wearing them and knowing what those are can help you select the type that’s advisable for you. It goes without saying that those decision should only be made with the help of your eye doctor

Since 1986 many have opted for Rigid Gas Permeable contact lenses. The more modern design allow for up to 5 times oxygen to pass through the lens than the older models The more oxygen can reach through the less the chance of a corneal infectionIn other words the less oxygen makes it through the higher your chances of an infection.

As the name ‘ Rigid ” implies these lens systems are less flexible than others which in turn entails a trade off in comfort. But, they may be better for adjusting astigmatism as a result. They also can last up to 2-3 years, which is longer than typical soft contact lenses. Many will require some type of soft lens, made from special hydrophilic plastic polymers that provide a lens that is flexible and therefore more comfortable. Although the hazard of tearing the lense has been greatly decreased in recent years because of better manufacturing techniques. They still demand a more regular replacement Soft lenses also stay in place extremely well and require a shorter adjustment period.

Though for many people a hard lens is till the only feasible choice. We know already they are less comfortable but to them their inflexibility is critical. The eyes of some patients simply require the rigidity of this type and they choose not to fall back on eyeglasses. Those with certain cases of astigmatism may not be capable to wear soft lenses and require these instead. In addition to the selections noted above there a re still several other alternatives.

Daily wear contacts are intended to be worn during the day, then taken out before bed. They’re used by about 80% of contact lens wearers. Here the pros and cons get more noted. It can be a minor hassle to insert and remove contact lenses every day. Whenever they’re taken out they have to be sterilised, normally overnight, before re-inserting the following morning..

On the plus side these daily wear contacts allow for presently the best option when it comes to minimise the risk of scarring or eye infection Letting the eye to relax and get exposed to air keeps it in the best health. All contacts nowadays reduce oxygen exposure slightly and normally well below the level the eye would get without them.

ALos by taking them out before bedtime there is naturally zero risk of having the lense slide off during the night – which could be rather painful in the morning.

On the other hand the perpetual touching of the eyes and the lens is not without risk either, not to speak of the inconvienece. Sometimes less is more and for when your eye doctor gives you the okay long-term wear lenses might be the better pick for you.They’re designed to be worn anywhere from overnight (2 days) to a week or even up to a month at a time, depending on the design and the patient.

Yo will pay for that convenience though in dollars and some risk factors

They tend to be more high-priced though prices change over time, of course, normally falling from a high. They also cut the air-eye contact, which ups the odds of infection slightly. Extended wear lenses also up the odds slightly of something going wrong, since they sit in the eye longer.

Some models, particularly the 30-day type, are somewhat stiffer and consequently slightly less comfortable. In each case, the odds of problems with modern contact lens models is still rather low for those individuals whose eyes allow long-term wearing.

Check out all the choices you have with your eye doctor and you certainly will discover the perfect pair of contact lenses for you
