If you are someone that has an astigmatism on at least of your eyes, there is a good chance that you need some form of vision correction. An astigmatism causes the shape of your cornea to be irregular and thus distort your vision slightly. The vision correction options for an astigmatism were limited to glasses for many years. Now, there are contacts available for individuals with an astigmatism, but there are some differences that you need to know. Use the following guide to learn everything you need to know about contacts specifically made for individuals with an astigmatism.
Colored Contacts May Not Be Best
There are colored contacts available for individuals with an astigmatism, but they may not be best because the colored contacts are often created differently than traditional contacts. The difference in production can distort the way that the contacts sit on your eye, making them not as effective as they would be if you did not have colored contacts.
Many of the Contacts Are Weighted
Because your cornea is irregularly shaped, contacts will not sit flush against your eye unless they are weighted. Weighted means that one edge of the contact will be heavier than the other edges to keep it toward the bottom of your eye. There will be a small line visible on the edge of the contact that is weighted. When putting the contacts in your eye, try to place that edge facing the bottom of your eye. As you blink, the contact will adjust and move the weighted portion where it needs to be regardless of how you put it in your eye though.
24-Hour Contacts May Not Be Available
There are some contacts on the market that are designed to be worn for days or even weeks at a time. Most contacts that are weighted will not be comfortable for you to wear on your eyes day in and day out because of the weight on your eyes. It is best to take the contacts out at night before you go to sleep.
It is important to realize that the first set of contacts you are prescribed may not be the perfect prescription for you. Finding your perfect prescription may take several tries, because finding the right contacts that fit your eyes will take a bit of trial and error. Once an optometrist like Dr Ron Sealock finds the right prescription, you can order your contacts whenever you need them to ensure you never have to go without them again.
