Contact Lenses Without A Prescription

In the first instance, it should be made clear that a prescription for contact lenses is not the same as a prescription for eyeglasses. So, one can say that it is not possible to do a direct eyeglass to contact lens conversion. However, the eyeglass prescription can be used in the construction of the contact lens prescription, by making allowances for the change in distance between the corrective material and the optic lens.

The prescription and fitting for contact lenses involves a good deal more than a similar prescription and fitting for spectacle lenses. For those new to wearing contact lenses, the fitting will be very new. This will again vary, depending on the type of lens being fitted.

The matter is further complicated depending on the type of lens being prescribed. Hard lens fit the eye differently to soft lenses, so allowances have to be made depending on the material being used for the contact lens itself.

Your contact lens practitioner will probably start by doing a refraction to determine the refractive error of your eyes, and then take further measurements, such as the tear film assessment and the corneal curvature to determine the best fitting contact lens and best material for your eyes. An exam and fitting for contact lenses can include your spectacle prescription.

One should also be aware of the increased maintenance cost of contact lenses. This includes more regular checks on your eyes, and more frequent replacement of the lenses. You should also include the cleaning and storage materials in the cost of lenses because they are a critical part of your eye health care.

In summary, whilst your eyeglass prescription can be used to help with the contact lens precription, it cannot be assumed that the former can be used to create the latter.

LASIK - A Corrective Laser Eye Surgery

A large number of surgeons who are not familiar with the corrective laser eye surgery reluctant to adopt it and, for several reasons: First, this treatment is much more technically difficult and not suitable for surgeons who do practice that occasionally, then this technique is much more expensive; finally, there is always the fear of damaging the cornea by making a "bad break". Results have shown that it is extremely rare for a serious complication to occur when LASIK surgery is performed by an experienced surgeon.

In 1997, a group of specialists engaged in a systematic review of their first 5 000 LASIK surgeries in order to assess the safety of this technique. This analysis was conducted in two parts: the operative phase at the time of surgery and postoperative phase in the months following surgery.

The operative phase:

In the case of eight patients, keratome created a piece is too thin or too short. Each time the piece was re-installed and a new surgery is performed six months later, has proved a success. None of these patients eyes has suffered a loss of visual potential.

The postoperative phase:

• In three cases, the day after the operation, surgeons had to replace the strip that the patient had moved, by rubbing the eye despite the protective shell;

• After the first day, surgeons haven't found on the strip of any patient any "fine line" that could affect the quality of vision;

• In any case there has been infection;

• In any case there has been development of scarring on the cornea (which often occurs during a photo-ablation of the surface);

• In any case there was, in the slide, debris requiring that one raises the slide again to clean;

• In any case there was epithelial cells forming in the strip and requiring that it raises the slide again to rid of these "infiltration epithelial.

• The number of eyes who lost two lines of vision on the map of visual acuity was extremely low (0.08%).

After all this information about the safety of LASIK if you have any doubt about it, I suggest that you use cheap contact lenses.

Glasses vs. Cheap Contact Lens

Fashion accessories and instruments of high-tech glasses are increasingly competing with cheap contact lens more discreetly. I will guide you in your choices, and why to choose them over glasses.

Cheap contact lens, a practical and aesthetic correction

Contact lenses are mainly used in the correction of myopia (80%) and to a lesser extent, farsightedness, astigmatism and presbyopia. They are placed in contact with the cornea and carved on each side so as to correct the anomaly.

Glasses allow light rays to focus again on the retina, rather than ahead of it as a myopia or backward as in hyperopia.

There are rigid or semi-rigid, whose maintenance is relatively easy but which are sometimes poorly tolerated by the eye. Other versions of flexible plastic polymer are easier to accept but require careful daily cleaning with a special product. There are also disposable lenses, which can keep one or two weeks later. In all cases, the ophthalmologist will check before prescribing the lenses if the eye secretes enough tears to support them.

A good peripheral vision with contact lenses

In addition to their aesthetic interest, contact lenses offer the advantage of providing a better field of vision as traditional glasses because of the lack of frame and because they follow the movements of the eye.

Peripheral vision is more ample and without grey area. They are therefore particularly appropriate in certain occupations that require a very good view, as surgeons, photographers...

Contact lenses are also more practical to wear at sports or outdoor activities. They also have the advantage to not fog, because the liquid wets the tear permanently.

Small constraints

However, contact lenses also have their drawbacks. In addition they require regular cleaning; they may lead to small irritations of the eye or your eyes will have allergies to the maintenance product.

More rarely, they can trigger abrasions or swelling of the cornea. Have regular eye examinations can check that everything goes well.

Don't worry for this, as I said this is more rarely. For me I'm wearing contact lens for 2 years without any problem.

Bifocal Contact Lenses

Bifocal contact lenses have been developed for people who have both nearsightedness and presbyopia. Bifocal lenses provide correction for both near and distance vision on each lens. A number of designs are available in hard and soft lenses. 

There are two main types of bifocal contact lenses:

Segmented (also called alternating or translating):

These resemble standard bifocal eyeglasses, in which there are two distinct areas, or segments, of the lens. You have to look through these different parts of the lens for distance vision (upper) and near vision (lower), and the lenses can move, making vision inconsistent. In some cases, the lenses may be weighted to keep them properly oriented on your eye.

Concentric or simultaneous:

These lenses provide correction for near or distance vision in the center of the lens, and correction for the other type of vision in a ring surrounding the center. There is usually a sharp boundary between the two areas. A special type of concentric lens, called aspheric, provides a gradual transition between the areas for near and distance vision. This can provide a way to correct for vision at intermediate distances. Because concentric or simultaneous contact lens designs provide correction for both near and distance vision close to the center of the lens, both near and far objects can be in focus at the same time. Your brain must learn to select the visual information it needs to form an image of either near or distant objects, so simultaneous bifocal contact lenses may require some adjustment.

Some people are unsatisfied with bifocal contact lenses. They may: 

Have a hard time adjusting to the different areas for near and distance vision.

Be dissatisfied with the quality of the vision correction provided by the lenses. 
Have problems with glare at night.

Some vision problems cannot be corrected very well by current designs for bifocal lenses.

Also, because they are more complex, bifocal contact lenses require a longer fitting process and are usually more expensive than single-vision contacts.

Can I Wear Contact Lenses ?

First thing (and it's going to reassure more than one): contact lenses can be worn at any age, regardless of whether the evolution of the problem of view is complete or not. Some lenses may even hinder the development of myopia, for example. Whether you are 12 years or 16 years, you can wear.

Second thing: if you've already tested the lenses in the past and it did not work, try again your chance today; contact lenses have largely evolved in a few years and can adapt to the majority of eyes , Including a slight case of dry eye.

And finally, the most important thing: you must make an appointment with an ophthalmologist before starting to wear contact lenses, even if you've already had one last week for another reason. This must make measurements and controls vital before giving its approval, including the size and curvature of the eye: without it, your lens is not appropriate. In general, he also explains the basics (save and remove the lenses ...) once you've bought them from your optician or on the Internet at a reduced price. It will conduct further checks to see if the lenses can not shift (adapted to the curvature) and if there is no problem (discomfort, irritation or dryness).

How Does It Work?

The majority of contact lenses today are composed of a flexible plastic, transparent, hydrophilic (composed mostly of water) and permeable to oxygen.

Their operation is simple: like any lens (microscope, telescope ...), they converge or diverge light, but here is how to correct a problem of view. For example, in myopia, vision is blurred because light rays are focused before the retina. To correct this problem, place a different lens on the eye. The lenses are extremely thin, but their orientation is enough to deflect light and thus correct view.

The contact lenses are now able to correct all the problems of view currents, including several at once. They put on the cornea of the eye but do not affect it, because they are selected by the tear film that maintains and strengthens them. The eye therefore accepts them without any problem, and they remain in place through natural adhesion.
