Astigmatism is a condition where a person has an unusually shaped cornea. Instead of one that is more spherical, they can now have one that is more oval in terms of its shape. The condition is actually much more popular than many people realize as it simply refers to the fact that the cornea does not focus light perfectly. It’s just that many people are not aware that they have astigmatism because it is fairly mild. If you think that you might, you probably should talk to your eye care professional about it.
One thing that you will learn at that time is that there are now a wide variety of toric lenses that are available for people who have astigmatism. Early on in the industry, there were contact lenses that were made specifically for this issue. They were all fairly rigid and like today, weighted on the bottom which helps them to maintain the proper orientation.
People with a less severe case of astigmatism will have more options. There are now toric lenses that are produced by all of the major brands and you can even get ones that are colored. Slight astigmatism sufferers can also get soft contact lenses that will still correct the problem. For people who have a more pronounced oval shape to their cornea, they may have to wear something more rigid and in severe cases even permanent contact lenses.
Ensure that you have a recent prescription if you are going to purchase contact lenses for astigmatism online. The quality of your vision will only be as good as the prescription, and you should also make sure to mention to your eye care professional if you feel that you might have this condition. They will be able to give you some insight into the best choices for you that may include other problems you have like dry eyes or very sensitive eyes.
