Whether you already wear contact lenses and are thinking of switching your prescription, thinking of swapping out your glasses for contact lenses or just found out you need corrective lenses and are trying to decide between contact lenses and glasses, you’ve probably already realized that there are a lot of options out there. Contact lenses can be expensive, so it’s important that you make an informed decision.

Here to help you do it are our experts at Price Family Eye Care Professionals LLC, your trusted provider of eye exams in Chillicothe, OH. After reading the following overview of the main types of contact lenses, we hope you will feel more confident when making a decision about which one is best for your eyes, and more prepared to have a discussion about contact lenses with your optometrist.

Toric vs. spherical lenses

Contact lenses, just like glasses, come in different shapes. However, the different shapes are not a “style” choice the way they are with eyeglass frames. Different contact lens shapes are used to correct certain vision impairments. The two types of contact lens shapes are spherical and toric.

Spherical lenses are used to treat nearsightedness, farsightedness and age-related farsightedness. Toric lenses, on the other hand, are cylindrical shaped, and they are used to treat astigmatism. Toric lenses are kept in position by gravity and blinking.

Daily-wear vs. extended-wear lenses

Unlike glasses, which can be taken on or off multiple times a day, contact lenses are meant to stay on your eyes for longer periods of time. However, some lenses are designed for daily wear, while others are made to be worn for extended periods. Daily contact lenses must be taken out at the end of the day to avoid damaging your eyes. In fact, some contact lenses are even disposable. Other contact lenses can be worn for several weeks before they need to be taken out.

It’s important to remember, however, that no matter which contact lenses you choose, you should follow the instructions on how long they can be worn. Trying to save money by keeping contact lenses in your eyes longer than recommended can cause damage to your eyes and even lead to infections.

Soft vs. hard

There are two main materials used to make contact lenses: hydrogels, which are soft, and plastic, which is hard. Both types of contact lenses are permeable, which means they allow oxygen and moisture to reach the cornea. Both lenses have their pros and cons. Soft lenses are more comfortable to wear, but they cannot correct all vision problems. Hard contact lenses, meanwhile, can be used to correct most vision problems, but they are less comfortable to wear, especially for long periods of time.
