Top Ten Things You Should Know About Contact Lenses

 by Alex Fir

1. Soft lenses are perceived by most patients and practitioners alike to be more immediately comfortable while adequately correcting vision. They come in all formats even toric and
bifocal. Disposable soft lenses take minimal but important care to maintain their safety and usefulness.

Soft lenses do absorb elements from the tears and the environment. They can change in fit with their age and cleanliness, perhaps causing a lack of oxygen to the eyes. Their surfaces
break down rapidly, causing a decreasing sharpness of vision.

On the other hand, many patients feel they see sharper and more clearly with rigid gas permeable (RGP) lenses. RGPs become very comfortable after adapting to them. They are easier and less expensive to maintain, last longer and are available in all formats. RGPs can
more easily be custom designed to offer a wider range of vision correction than soft lenses. They can breathe more oxygen, don't deteriorate as fast and don't absorb things as easily as soft lenses.

2. Soft lenses generally center by themselves if they fit well. Just put them straight on the cornea and they will go where they belong. Use the iris, the colored part of the eye, as a
guide. Make sure you have a competent eye care practitioner evaluate the fit of your lenses before you wear them, though. Improperly fit soft lenses can cause damage to your eyes!

Almost all nearsighted people can wear contact lenses, no matter how high their prescription. In fact, there are contact lens laboratories that make custom lenses up to -30.00 diopters! It is essential to follow your contact lens practitioner's rules, however.
Contact lenses are extremely safe when prescribed and cared for properly.

4. Improperly worn contact lenses can cause a loss of oxygen to the cornea, which in turn can lead to blood vessels growing over the front of your eyes, infections, lid changes, allergies, corneal warping, corneal swelling and possibly even blindness.

Do not share contact lenses with your friends. Everyone's tears are filled with normal bacteria, but transferring these bacteria to someone else's eyes is not a good idea. And not
only is there a risk of infection, if the lenses don't fit, the eye can suffer from a lack of oxygen or develop other problems.

6. Contact lenses are medical devices. Changing parameters should be done under the supervision of an eye care practitioner. Do not take chances!

7. If you sunbathe while wearing contact lenses, there is no problem with heat. But your corneas can swell and make your lenses fit tighter, causing some temporary redness and
irritation. Put some form of lubricating drops in your eyes before tanning. Wear protective glasses to block the really harmful UV radiation from getting to your eyes it has been linked to cataracts, macular degeneration, etc.

8. Bloodshot eyes are a sign that something is not right. It could be as simple as a solution allergy or dirty lenses. But it could also be a sign that your corneas are not getting enough oxygen. Go see your eye care practitioner and find out why your eyes are so red!

Eyeglass prescriptions are higher than contact lens prescriptions because contact lenses sit on the eye, whereas eyeglasses sit in space in front of the eye. This is called the vertex
distance. The closer a lens sits to the eye, the less strength is needed to focus light on the retina. And the stronger the prescription, the more the power adjustment. This is true for
both soft and RGP lenses.

10. Some contact lens practitioners find that lenses with lower water content can sometimes be better for people who have dry eyes. But some patients actually do better with high-water contact lenses. It has long been felt by some practitioners that the thicker the lens, the better, as well.

Valuable Tips To Finding Cheap Contacts Online

by William Lezubski

When searching the Internet for cheap contacts, you may feel like you're trekking through a jungle of contact lens suppliers, and as you stumble on their contact site, they all claim to be offering cheap contact lenses for the lowest prices, or so it would seem!

Some may even provide incentives such as free solutions, contact lens cases, and even free shipping to get your business. So how do you decide on the best company to deal with, and how do you actually know you're getting the best lenses online for the cheapest price?

The only way you can find out if your getting the best deals is to search each individual lens business online, and do some comparison-shopping. We will provide you 3 tips that may help you find the best bargains on contacts, and help you maximize your savings.

When searching for contacts online buy only from reputable suppliers

Tip #1: Even though the site you land on may claim they have cheap lenses, make sure they're a reputable and well known company! You want to buy only from trustworthy online suppliers that offer name brands like Acuvue, Bausch & Lomb, Freshlook, CooperVision, or Biomedics. They will offer you fantastic discounts on top brand lenses, due to their significant volume of lenses they sell over the Internet.

Tip #2:
Other contact lens companies that discount will say that when you purchase their cheap eyewear, that their savings will generally be up to 80% off retail. However, do they offer free shipping, or do they have price guarantees if you happen to find your contacts at a lower discount price somewhere else. Also make sure they have a policy in writing for returns, and detailed instructions for replacements. If they don't honor returns, then you will be stuck with a product you don't need, and what kind of savings is that!

Tip #3: Many so-called suppliers will offer you a really attractive contacts discount on your first order, but if you're planning on purchasing a disposable lens, you want to make sure the next time you place a re-order, that you're going to receive the same prescription price you paid the first time. Find this out before placing your order, and get it in writing that the cost will stay the same.

Companies we have come across that have earned a reputation for the finest lenses at competitive discount prices are 1-800Contacts, TheContactLensesStore, Lens.com, ACLens, and DiscountContactLenses to name a few!

How To Choose The Right Contact Lenses

by Peter Smithson

Today's contact lenses are used to correct specific vision problems or to change eye color. With all of the advances in technology, more people than ever before are able to wear contacts. There are a variety of lenses available including disposable, extended wear, flexible war, and gas permeable and even contacts for special needs.

You can change or enhance your natural eye color, even if you don't require vision correction. With color altering lenses, you can achieve just the right look for a costume or simply a magical pair of green eyes that will look spectacular with a new dress. It gives a whole new meaning to the lyric 'don't it make my brown eyes, blue.'

Disposable lenses are perfect for the person who doesn't have time to do daily care and cleaning of their contacts.
Depending on the brand your optometrist recommends, you can choose either a daily disposable or one that will last one week or two weeks.

Disposables are exactly what their name implies; you take them out and throw them away each day. Conveniently,
disposables are available for different eye types now including those with astigmatism and if you were looking to try out colored contacts for a while, disposable lenses come in varying shades as well.

Gas permeable contacts are designed for people who require a very specialized prescription. In some cases, astigmatisms on the eye make it very hard to fit the candidate with the right level of correction. A person whose vision is 20/180 may not correct to 20/20 with other types of lenses. Gas permeable is more expensive, but the ultimate decision lies between the optometrist and the patient.

Flexible wear and extended wear lenses are designed for those who like to be able to sleep in their contacts rather than deal with putting them in and taking them out several times a day. These are especially useful for those who travel a great deal or are frequently away from home. No worries about having to carry your lens cleaning kit with you everywhere you go.

More than 30 million people wear contact lenses and it requires a visit to your eye care professional that can then determine if you're a candidate for contacts. With so much variety and so many advances, the chances are good that your local optometrist has the right contact lens for you.
