 Something about Toric Contact Lens

14/12/2010

Do you know what toric contact lenses are? I didn't know them either until one day I found I had a blurry vision. I went to the doctor who told that I had astigmatism. With explanation from the doctor, I came to be aware that astigmatism is one where rays that propagate in two perpendicular planes have different foci, and corrective lenses are needed to get it corrected. However, if you do not want to wear eyeglasses, which constitutes a burden to the wearers, you could choose a special contact lenses designed  for astigmatism correction, called Toric contact lenses.

Compared with regular soft contacts, toric contact lenses have two powers in them, created with curvatures at different angles, one for astigmatism while the other for either myopia or hyperopia. What's more, they are weighted which enables them to sit on eyes properly and correctly in place. Another feature is that there is a line on the lens near the identifying numbers to indicate the bottom of th lens, therefore, at the very few seconds after you put them on, you would experience discomfort or blurry vision. However, if your blink for sometime, everything would turn out to be ok.

Facing so many different brands, one who firstly comes to contact toric contact lenses would feel puzzled which one to choose. The suggestion is to try one by one to find the most suitable one for you. As a matter of fact, your eye doctor will advise certain brands for you according to you personal eye condition. And those who need a high prescription should choose lighter weight, for heavier ones would restrict oxygen flow to the eye, resulting in dry eye symptoms.

Besides wearing Toric contact lenses, astigmatism patients also have an option of undergoing a surgery. But the problem is that an eye surgery always costs a lot, and not every one is able to afford. What's more, patients have to take a risk to have a surgery and this may not what one wants.

In my opinion, the best way to keep oneself away from toric contact lenses and eye surgeries is to prevent the emergence of any eye problems. If you, up to now, have a good eyesight and do not have any eye disease, you are suggested to get regular eye examinations every year. And you have to keep doing it, because eyes are constantly changing through out life.
