My name is Lilith Maclin and if you suffer from a digestive disorder, you can find a wealth of information about this type of medical condition in my blog. Three years ago, my husband was having severe stomach cramps and his doctor told him that he had a digestive disorder called ulcerative colitis. After my husband was diagnosed, I did thorough research to learn how to control and manage this disorder. We kept track of everything that my husband ate and when a certain food caused a flare-up of his condition, he eliminated that food from his diet. By learning all we could about this digestive disorder, my husband has been able to live pain free. If you want more information about this disorder and how to manage it, you can find it here by reading my blog.
You may have been told you have a complicated prescription and that you couldn't wear contact lenses. Modern contact lenses have many features to correct the vision for different eyesight issues. No longer are contact lenses for those with single vision or no astigmatism. Many people can now wear them when they thought they couldn't before. Here are some common vision problems and how contact lenses may work in each situation.
Moderate myopia: People with moderate myopia (nearsightedness) often have to put up with thick lenses in their glasses. This may have meant thick contact lenses in the past, as well. Contact lenses nowadays are made lighter with better gas exchange than before. People with a higher degree of myopia may be able to wear contact lenses. However, extreme nearsightedness, such as that over -6.00D, may still require glasses.
Astigmatism: Special contact lenses, called toric lenses, have been developed to help with astigmatism. The toric lens is shaped to match the imperfections of the cornea. It is also ballasted so that it is always weighted at the bottom no matter how it moves in the eye. This ballasting helps to keep the prescription in place. Therefore, it's important to get a precise fit for the maximum clarity and comfort.
Bifocals and multifocals: Bifocal and multifocal contact lenses work in a similar way as glasses do. These contacts are often said to work better than another technique called "monovision". With monovision, one eye is corrected for distance vision and the other eye is corrected for close-up vision. With bifocal and multifocal contact lenses, both eyes are corrected to see both distance and close up.
Post-surgical contact lenses: Some patients may need further correction after vision-correction surgery. The scars left on the cornea from the surgery may complicate or eliminate the ability to use contacts. While it is possible for people who have had surgery to wear contacts again, they may need more fittings. Special contact lenses have been developed specifically for people who have had vision correction surgery. Talk to your eye doctor about the availability of these lenses and whether you are a candidate for them.
The exams for these special considerations as well as the lenses will cost more than a regular contact lens fitting. Even though there are new technologies with contact lenses that make them available to more people, there are some people who still should not wear them. Anyone with tear duct issues or dry eyes as well as anyone with corneal disease may not be able to wear contacts. Your eye doctor should tell you if you are at risk for any issues from wearing contact lenses.
