For years, more and more people have been switching to contact lenses. Contact lens technology has evolved rapidly and with today’s variety of contact lenses, there are lenses for just about everyone. Switching from eyeglasses to contact lenses begins with an eye exam for contact lenses. After the contact lens exam comes a separate contact lens fitting session.
A comprehensive eye exam comes first
Before being fit with contact lenses, a comprehensive eye exam for contact lenses is performed. In this exam, your eye doctor in Toledo, OH determines your prescription for corrective lenses (just a glasses prescription at this point) and checks for any eye health problems or other issues that may interfere with successful contact lens wear.
If all looks good during your eye exam, the next step is a contact lens consultation and fitting.
What to expect during a contact lens fitting
With so many contact lens choices, the first part of the consultation is a discussion with your eye doctor about your lifestyle and preferences regarding contact lenses. One choice that today’s contact lenses allow you to make is whether you want to change your eye color. Different eye colors are available with contact lenses. Other options include whether you want contact lenses that are designed to be replaced daily or those which can be worn for more extended periods. Most people choose soft contact lenses for their ease and comfort. However, there are also advantages of hard or what is called rigid gas permeable (GP) lenses. All the specifics will be discussed prior to your contact lens fitting.
Believe it or not, if you need bifocals, you can even opt for multifocal contact lenses or monovision (a prescribing technique where one contact lens corrects your distance vision and the other lens corrects your near vision). Once you have determined the type of contacts you want, the next step is the actual contact lens fitting.
If You Are New Contacts Wearer
If this is the first time you are trying contact lens, you need to have a complete eye exam and evaluation to make certain you are a good candidate for wearing contacts. Your doctor will ask about your vision goals. For example, you may only want to wear contacts for sports once per week, or you want your contacts to replace your glasses for everyday activities.
There are many choices in contact lenses these days, so your Toledo optometrist will listen carefully and choose the lens that will best meet all your needs.
Additional Tests and Procedures:
Your eye doctor will administer various tests designed to evaluate your eyes for contact lens wear. One important test is corneal topography, a test that maps out the different aspects of your cornea. Corneal topography displays results in a way that is very similar to the topography of mountains. The test results in a map of colors – reddish colors display steeper areas of the cornea, and bluish colors describe flatter areas. Contact lenses rest on your cornea, so it’s important that corneal curvature be measured precisely to ensure an optimal and healthy fit.
Another important test is the slit lamp examination. The slit lamp exam is generally performed during a regular eye examination, however, your eye doctor will spend more time doing a slit lamp examination for a patient who wears contact lenses. Sometimes eye health problems are diagnosed during this test, and they need to be treated before the contact lens fitting can proceed.

There are many differences between glasses and contact lenses, but there are also similarities. Both correct your vision, require care in handling and diligence in cleaning, and both are affordable.
Best contact lenses for astigmatism
There are three types of contact lenses that are suitable for people with astigmatism. Soft toric contact lenses, hybrid contact lenses, and gas permeable (hard) contact lenses. To know which one is best for you, speak with an eye doctor who specializes in contact lens fittings. There are different considerations for each type of lens. You will need to speak to your eye doctor about what will work for your lifestyle, and your eye doctor will need to examine your eyes to determine which type of lens will best correct your vision. Of course, comfort is as important as vision correction. Your doctor may try several lenses to see which one works best for your particular eyes.
Best contact lenses for dry eye
Dry eyes present a particular problem for contact wearers. However, there are excellent contact lenses for dry eye sufferers. Most people with dry eye prefer to wear soft contact lenses because they are often more comfortable. Soft contact lenses are made of a flexible plastic that allows oxygen to pass through to the eye. Soft lenses are called hydrogel, which is a gel made mostly of water. There are types that can be worn for a day and then thrown out (disposable), or kept in for up to 30 days (extended wear).
Extended-wear contacts can cause more problems with dry eye. Doctors recommend switching to disposable lenses. Changing your contact lenses often prevents protein deposits from forming on the lenses, which can make your eyes feel even. Lenses that are made from silicone hydrogel cause less water to evaporate and may reduce dry eye compared to regular hydrogel contacts. Proclear is the one brand of disposable lenses that is FDA-approved for people with dry eye syndrome. It contains phosphorylcholine (PC), which is supposed to attract water and keep your eyes feeling moist.
Another point to consider is lens water content. Soft contact lenses are categorized by how much water they contain. Low water content lenses contain less than 40% water, while high water content lenses contain more than 60% water. Lenses with high water content can actually cause drier eye than those with lower water content. They send more moisture to the eye when you first put them in, but can dry out faster. Your eye doctor may recommend that you try lenses with different water contents until you find one that works for you.
Another consideration is lens size. Most contact lenses measure about 9 millimeters (mm) in diameter. They cover just the colored part of the eye (the iris).
Scleral contact lenses measure 15 to 22 mm. They cover the white part of the eye (the scleral). Scleral lenses are also gas-permeable, meaning they let oxygen reach the eye’s surface. They can help keep more moisture in the eye than smaller contact lenses.
The bottom line for choosing contacts that will be good for your eyes when you suffer from dry eyes, is to consult an eye doctor who specializes in fitting contact lenses. Your Toledo eye care expert has experience knowing which contact lenses work best for people with dry eyes, and will be able to guide you better than anyone else, based on your own particular needs and eye health.
