Contact lenses are a great alternative to prescription eyeglasses for many people. They are small, curved lenses that fit right over your eye and provide vision correction for common vision problems such as astigmatism, myopia, presbyopia and more. One of the greatest benefits of contact lenses over eyeglasses is that it frees one from having to wear bulky eyeglass frames on their face. Many active people such as those who spend much time outdoors or participate in sports appreciate the freedom from frames very much.

While contact lenses can turn out to be much more comfortable in the long run than prescription eyeglasses, there is a period of adjustment in the beginning. Before you are used to your contact lenses and are familiar with how they feel, you may question whether your contacts fit properly or if they are in properly. This guide will help you determine how to evaluate if your contact lenses fit as they should and will also provide some general tips on contact lens insertion.

At the Eye Doctor’s Office

When your eye care professional diagnoses you with a vision problem that requires correction, you will discuss eyeglasses versus contact lenses and you may decide you prefer to try contact lenses. Your eye doctor will go over the several types of contact lenses available and may ask you several questions about your lifestyle in order to help determine which type of contact lenses will be best for you. Next, your optician will measure the surface of your eye in order to determine its curvature. He or she will determine key measurements with an instrument called a keratometer. Because everyone’s eyes have different shapes, sizes and levels of curvature, your eye doctor may use a computer to further measure certain aspects of the surface of your eyes. This may take several minutes, but try to be patient and helpful as it is crucial to have proper measurements if your contact lenses are to fit correctly.

After all measurements are taken, your eye doctor will have a good idea of exactly which size and curve your contact lenses should be. He or she will hopefully have a pair of contact lenses to fit your size and prescription right in their office so that they can help you insert them for the time and go over the fit with you. Another good reason for trying on your first pair of contact lenses at the optician’s office is that they can use a biomicroscope to help judge the fit of the lenses. It will generally take 10 to 15 minutes for the contact lens to settle into your eye, but after that, the doctor will look for any signs indicating that the lens is not a perfect fit. Some of the things he or she will look for are:

- Lenses that are too flat or too steep for your eyes can cause damage to your cornea and should be carefully avoided. These will generally cause great discomfort, so you will definitely know something is wrong if this is the case.
- Shifting of the contact lens off your eye and onto the whites of your eyes. Generally this would indicate that you might need a slightly different size.

Putting in Your Contact Lenses

To wear your contacts correctly and ensure the proper fit, follow these tips
- Always wash and dry your hands first
- Place the lens on the tip of your index finger, ensuring it’s rightside-up
- Hold your upper eye lid open with your other hand
- Gently place the lens on your eye as you stare straight into a mirror
- Release your eyelids and blink gently

Lasik is a type of eye surgery used to help improve the eye sight of individuals all over the world. The work LASIK itself is actually an acronym for the words: laser assisted in situ keratomileusis. It is possible now due to many advances in technology over the years. It is used to correct problems that an individual may have with their lens. These problems can include long sightedness, short sightedness and astigmatism. What it does is correct problems that the lens may have in focusing on things whether they are near of far away. It is performed by using a laser to make corrections to the eye’s lens thus allowing individuals to focus and perceive things more clearly.

During the first part of the procedure, a thin layer of the eyes cornea is detached and lifted. Part of it remains attached so that it is like a flap that is still connected to the cornea. The laser is then used to burn away portions of the cornea to change its shape. This is much in the same way camera lenses are cut and polished so that they can focus clearly things. The lens is given a smoother curvature and at the end of the procedure, the flap that was detached previously is put back into position. When everything is completed, the cornea has better control over the light that enters the eye and it is able to focus them more accurately on to the retina.

This procedure is a great choice for people who have had to wear glasses in order to see properly and can create a world of difference in your vision. Often times this procedure can be covered by your insurance, however this is not always the case. Contact your insurance provider to find out if you are covered. If you are interested in Lasik eye surgery, consult your eye doctor to see if you are a potential candidate.

Your vision is important and Lasik is a cutting edge and innovative way to take care of it and make sure that it will be clear for a long time to come. Whether you have far sightedness, near sightedness, or astigmatism, talk to your doctor and take the steps necessary to keep your vision as clear as possible for years to come. Not to mention get rid of those glasses that have troubled you for all those years.

Ophthalmology has realized the betterment of its field as it was honed and the knowledge over this field was improved over the constraints and development that it has undergone in refractive cataract surgery. It is said that with the current innovation and the latest generation of ophthalmology, it had reached to the point where “cataract surgery is refractive surgery”. This means that from the previous cases of letting the patients wear glasses on regular basis after cataract surgery, now, there are premium lenses already which will not refuse the right of the patients to have the opportunity of achieving good uncorrected distance and near vision exist evidently.

Thus, from then on, what the personnel or enthusiast were lacking was the necessary time to deal with those patients and insufficiency in skill sets of the surgeon and ophthalmologists who experienced significant rational instability and inconsistency in outcomes. However, those were given solution and now, technology has paved the way to greater innovation in achieving visual acuity which complements with emmetropia.

At the end of any surgical operations, they have set a standard goal of correcting various problems regarding the prevalent eye irregularities such as nearsightedness, farsightedness and astigmatism. It had been a greater help because it is not possible to reduce the magnitude of higher-order optical distortion such as spherical aberration. Also, intervention to presbyopia introduces the newly developed intra ocular lenses which can correct the said condition.

In this way, refractive surgery is divided into two basic types of corrective surgery. The first one is by changing the curvature of the cornea and the second type is by changing the internal optics of the eye by either replacing the natural lens of the eye or by using an intra ocular lens and attaching it to the natural lens. Through radial keratomy, incisions are made to various part of the cornea to correct nearsightedness and astigmatism. In the outer part of the cornea, it is incised to flatten the cornea in order to correct a mild to moderate degree of nearsightedness. With astigmatic keratomy, circumferential incision is made in the outer part of the cornea.

There are other options in refractive surgery which includes the following: Photorefractive Keratomy (PRK), Laser in-situ epithelial keratomileusis (LASEK), Laser in-situ keratomileusis (LASIK), Refractive replacement, and Phakic intraocular lens implantation. As with any type of surgery, we must be open that compilations can occur. The patient can experience complications such as flaring ones eye with lights at night, this may occur most of the time to those young patients who have large pupils; under correction or over correct is probable and may need for a second “enhancement” procedure; glasses may be required even after this surgery, and rarely corneal abnormality may need to use contact lenses; and in LASIK surgery, complications in the cutting of the corneal flap can lead to corneal irregularity.
