Sunglasses, They Make You Look Great!

Modern contact lenses are comfortable, extended (unless by purpose, as in disposables) and very sound. Yet, there are some perils and limits in wearing them and knowing what those are can assist you choose the type that’s best for you. Of course, any such determination should be made in consultation with your eye care professional.

Since 1986 many have preferred for Rigid Gas Permeable contact lenses. Popular designs provide for up to five times more oxygen diffusion through the plastic than those of the past. That feature is essential in minimise the odds of corneal infection. The less oxygen that makes it to the eye, the higher the odds of an infection.

On the downside, RGP lenses are a little less variable than other types, making them less comfy for some. But, they may be best for adjusting 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, produced from special hydrophilic plastic polymers that supply a lens that is flexible and hence more comfortable. Current manufacturing proficiencies make possible a lens that doesn’t suffer from a high likelihood of tearing, as did those in early decades, but they do need more frequent replacement. Soft lenses also stay in place exceedingly well and require a shorter adjustment period.

Yet, for many, a hard lens is still the only option. While often less comfy, and even though they raise the odds of marking or infection slightly, their inflexibleness is essential. The eyes of some patients plainly require the rigidity of this type and they prefer not to fall back on glasses. Those with particular types of astigmatism may not be able to wear soft lenses and demand these instead.

Beyond those classes there are still various picks.

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 evident. It can be a minor hassle to insert and remove contact lenses each day. Whenever they’re removed they have to be sterilised, commonly overnight, before re-inserting the next morning.

But daily wear contacts (currently) offer the best possible pick for those looking to accomplish the absolute token gamble of eye infection and marking. Providing the eye to relax and get exposed to air keeps it in the best health. All contacts today cut oxygen exposure somewhat and usually well under the level the eye would receive without them.

Removing them at night also cuts the odds to zero of getting the contact slide off the cornea during rest, where it could be a pain (literally and figuratively) to retrieve in the morning.

Still, touching the eye and/or the contact is also not wholly without jeopardy, and the action is a little inconvenient. Fewer changes can also be good. For those whose doctors say it’s safe, extended wear contacts are a easy choice. They’re fashioned to be worn anyplace 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 ingredient comes at a price, in dollars and risk.

They tend to be more expensive though costs vary over time, of course, usually falling from a high. They also reduce the air-eye contact, which ups the odds of infection slightly. Extended wear lenses also up the odds somewhat of something going wrong, since they sit in the eye longer.

Some models, in particular the 30-day type, are slightly stiffer and hence slimly less comfy. In every case, the odds of problems with modern contact lens models is still quite low for those people whose eyes allow for long-term wearing.

Investigate the options in consultation with your eye care professional and you’ll soon find the right pair of contact lenses for you.
