No Prescription Contact Lenses

View:

Far back in the history of mankind, in 1508, Leonardo da Vinci described and drew the sketch to express his idea of a contact lens. But it was in 1827 that Sir John Hershel, an English astronomer astounded the world with his idea of making a mold of a human eye so that a lens could be made to fit perfectly. Sixty years later in 1887. F.A. Muller, a German glassblower used these ideas to create the world's first known contact lens.

Contact lenses are full contact optical accessories which rest directly on the cornea to facilitate a better and natural vision than contemporary spectacles. Distortion due to side vision and eye-lens distance is nullified in using contact lenses. With spectacles the eye-lens distance makes the size of the objects appear bigger or smaller than actual depending upon whether you are far sighted or near sighted.

Spectacles or eye glasses block the peripheral vision due to the frame. When you look sideways, upwards or downwards, you are looking outside the perimeter of the lens which makes you look at object without the eye glasses resulting in distorted or blurred vision because you are not looking through the optic zone. This is more so because of the smaller frames in vogue today. When you wear contact lenses, irrespective of which way you look, you are always looking through the optic zone resulting in perfect vision. Contact lenses are immune to scratches and easy breakage. They are also immune to fogging and will give clear vision even on a rainy day.

Contact lenses are basically of two kinds; Soft contact lenses and RGP (rigid gas permeable) contact lenses. Both these kinds of contact lenses can be used to correct all kinds of vision i.e. myopia, hyperopia, astigmatism and presbyopia. Soft lenses are easier to wear and more comfortable while using initially, the reason why they are chosen by more than 80% users. RGP lenses are used only when you need to wear them continuously over a long period of time.

Choosing a contact lens depends upon the outcome of your optical examination by your ophthalmologist. It is always wise to inform him that you wish to use contact lenses and not spectacles, so that the ophthalmologist can test your eyes accordingly and make time to fit your contact lenses. This might be against your ophthalmologist's preferences, as some of them do not recommend contact lenses unless you ask them especially for a set.

Wearing contact lenses is best suited to some people like sports persons, riders, acrobats etc. because they do not interfere in their professional life. Contact lenses can correct all kinds of vision as referred above. If you are in any of the above professions and prefer to wear glasses, you can wear contact lenses on the job and swap them for spectacles in your leisure time activities.

No Prescription Contact Lenses

The healthiest soft contact lenses currently on the market are daily disposables, biocompatible contact lenses and silicone hydrogel lenses.

Daily disposable lenses

You probably know that even if you follow the doctor's instructions for cleaning your contact lenses, they never feel as good in your eyes as when you just take them of the package for the first time. And if you are a bit casual about caring for your lenses, they can feel even worse. There is a simple solution to this problem - contact lenses that you can get fresh from the pack every morning and throw out in the evening.

Many eye doctors agree that daily disposable contact lenses are the healthiest choice, when it comes to contacts. Comfort and convenience are not the only benefits of daily disposable lenses. There is also no day-to-day deposit build-up, and the risk of eye infection is minimal. And if you lose or accidentally tear the lens, no problem - just take another one from the box.

The price of daily disposable contact lenses had decreased, over the last few years, and now they are very affordable. Bearing in mind that you will not need any lens care products, dailies won't cost you significantly more than monthly disposables. Actually, daily disposable lenses can also be a money saver, if you wear your contacts only once in awhile. Weekly and monthly disposable lenses have to be thrown out after their time is down, even if you wore them only once. If you open a fresh package of daily contacts every time you need to wear contact lenses, though - and if this is not too often - then a 30 lens pack will last you a long time.

There are many daily disposable contacts on the market. 1 Day Acuvue by Johnson and Johnson, Focus Dailies by Ciba Vision and Soflens One Day by Bausch & Lomb are healthy and affordable daily disposable contacts.

Biocompatible contact lenses

Do you know why your contact lenses don't feel so good in your eyes by the end of the day? The main reason is that your body tries to reject foreign objects in your eyes by coating them with proteins, lipids and other cells from the surrounding fluids. But there is a way to prevent this "rejection" reaction - it is possible to create a lens that is compatible with your body. In other words, your body won't see the lens as ‘foreign' and won't try to fight it.

Modern technology can create healthy contact lenses with PC (phosphorylcholine) - a substance that occurs naturally in human cells. The contact lens we are talking about, here, is Proclear Compatibles, by Cooper Vision. The PC used in Proclear Compatibles creates a healthy biocompatible lens material that feels comfortable and moist over several hours. This lens is also very resistant to dehydration, so it is ideal for people who suffer from dry eyes.

Silicon hydrogel contacts

You probably know that in the case of conventional contact lenses, the higher the percentage of water is, the better it is for you. However, there is another way to keep your lenses moist, with a low (30-40%) water content and a new material - silicon hydrogel.

Since the lens contains less water, it is less prone to dehydration, and the silicon hydrogel material makes it feel moist and very soft in your eye.

Successful silicon lenses are Acuvue Advance by Johnson and Johnson and PureVision by Bausch & Lomb (both of these brands also have toric lenses). Acuvue Oasys is the newest silicon hydrogel contact lens, and deserves a special word. It is made from an improved material senofilcon A and provides extreme comfort for people with dry and sensitive eyes.

Proclear Compatibles, mentioned above, also belongs to the silicon hydrogel group of lenses.

Are your current contact lenses healthy? If you are still prescribed traditional monthly disposable or - God forbid! - annual replacement contact lenses, then it is time to switch to a healthier option. Ask your doctor if he or she can fit you with any of the healthy contact lenses mentioned above, and feel the difference.
