The Latest contact lenses are comfortable, long-lasting (unless by design, as in disposables) and very safe. That’s not to say that there aren’t some dangers involved with wearing contact lenses and once you know them it’s easier to select the right type for you Of course, any such decision should be made in consultation with your eye care professional.

Since 1986 many have opted for Rigid Gas Permeable contact lenses. Modern designs allow for up to five times more oxygen diffusion through the plastic than those of the past. The more oxygen can pass through the less the hazard of a corneal infectionIn other words the less oxygen makes it through the higher your risks of an infection.

As the name ‘ Rigid ” implies these lenses are less flexible than others which in turn entails a trade off in comfort. But, they may be better for correcting astigmatism as a result. They also can last up to 2-3 years, which is longer than regular soft contact lenses. Many will wish some type of soft lens, made from unique hydrophilic plastic polymers that offer a lens that is flexible and therefore more comfortable. Although the hazard of tearing the lense has been greatly cut in recent years because of better manufacturing techniques. They still require a more regular replacement An extra incentive with soft lenses is that they stay in place exceedingly well and need a shorter time to get used to.

Though for many people a hard lens is till the only possible selection. We know already they are less comfortable but to them their inflexibility is essential. Their eyes simply need the inflexibility and they put up with the less comfortable wear in order not to want eyeglasses again. Also particular types of astigmatism cannot wear soft lenses. Beyond those categories there are still several options.

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

But daily wear contacts (currently) provide the best possible option for those looking to reach the absolute minimal risk of eye infection and scarring. Permitting the eye to relax and get exposed to air keeps it in the best health. All contacts today trim oxygen exposure slightly and usually well below the level the eye would receive 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 constant touching of the eyes and the lens is not without peril 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 best option 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.

That convenience factor comes at a price, in dollars and risk.

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 somewhat. Another factor is simply the fact that they sit longer in the eye, so your odds are going up a little bit that something goes wrong.

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

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