Hamden CT Laser Vision Correction: All You Need To Know About Astigmatism
What is astigmatism?
Astigmatism is a medical condition that prevents the human eye from having a clear vision. In that condition, the light that comes into the eye is not evenly bent and so it does not give clear vision. A lot of people are suffering from various degrees of astigmatism.
Major symptoms of astigmatism
Some of the symptoms of the condition are eye strain, vertical lines that appear tilted, and blurry vision. There may be other symptoms but the ones listed above are the common ones. Once you notice any of the symptoms, in any of your eyes, you should see an optometrist for a thorough eye exam as quickly as possible. It is usually easier to correct it at an early stage.
Treatment of astigmatism
A very effective way to correct astigmatism is the use of contact lenses and glasses. There are three major types of contact lenses. There are gas permeable, hybrid, and toric contact lenses. Toric lenses are prescribed more often because they have features that make them remain firm on the face.
The most common astigmatism cases are caused by curvature of the lens or the cornea. This type of astigmatism is also referred to as lenticular, corneal, or regular astigmatism. The lens or the cornea is curved and as such, the refractive index of the eye on the horizontal plane differs from that of the vertical plane and this may lead to any of the following:
Seeing fine details with so much difficulty or not seeing it at all
Vertical lines that appear tilted
Contact lenses have the ability to provide different refractive powers on the horizontal and vertical orientations of the eye and this addresses the corrects the condition.
Choosing suitable contact lenses
After confirming that you have astigmatism, your doctor will use the cause and the severity of the condition to determine the best contact lenses for your eyes. Besides, contact lenses need to be fitted in the correct way to achieve the best result.
Features of toric contact lenses that make them the best for astigmatism
Toric lenses have some features that help them stay in place when you put them on. These features are:
The lenses are relatively heavier and thicker. This feature is known as ballasting
Some zones are thicker than other zones
A part of the bottom lens has been truncated
In other words, fitting the contact lenses to your eyes is equally as important as choosing the right lenses. This is why you need to give it to professionals. You need to understand that toric contact lenses have a middle axis. The axis is the part that keeps your line of vision clear. If the axis is not in its right position, the eye’s visual clarity may be compromised.
On the other hand, if you want a permanent solution to astigmatism, you need to consider Hamden CT laser vision correction. It is also known as LASIK. It is a technique used in correcting eye defects through the use of laser. The biggest advantage that Hamden CT laser vision correction has over other types of treatment is its long-term results. Its result is permanent.
Another reason you should consider Hamden CT laser vision correction is the fact that you will no longer need to put on any eyeglasses or contact lenses after the procedure. This is why people believe that even though the procedure costs a little more, it is still more cost effective in the long run. You will have to change the lenses of your glasses multiple times over the years. So, laser vision correction saves you the cost of changing your lenses or eyewear.
Whenever you notice any of the symptoms of astigmatism in any of your eyes, you should see your optometrist for a thorough eye exam as soon as possible. The earlier it is diagnosed the better.
