5 Commonly Asked Questions About Contact Lenses
Whether you're receiving contact lenses for the first time, or you've had them for years, there are probably plenty of questions that you have about the phenomenon of contact lenses. Thankfully, you have this guide at your fingertips. Throughout the course of this brief article, you will learn of a few commonly asked questions about contact lenses.
Can You Wear Lenses With Astigmatism?
Yes. Although in years past, contact lenses were simply not designed for people with astigmatism, this is no longer the case. People with astigmatism can now wear lenses and enjoy the many comforts and benefits of them.
What Are Some Basic Care Techniques?
First and foremost, it is important to not become complacent about lens care and maintenance. Make sure that you stay diligent about taking care of your lenses. Make sure that you always wash your hands before inserting or removing your contact lenses. Not doing so is a surefire way to ensure that you spread bacteria or debris into your eye. As a follow up, it is also imperative that you use contact solution at designated times in order to keep your lenses clean.
Why Must Your Corneal Shape Be Measured?
After contact lenses have been prescribed to you, you may undergo a process that measures your cornea shape. This is due to the fact that lenses rest on your cornea. A corneal topographer is a device that will digitally measure the shape of your cornea such that you find a prescription that will fit your cornea nearly precisely.
What Should You Do If Your Lenses Feel Uncomfortable?
The first thing you should do is evaluate if you're caring for the lenses in a way that is causing this discomfort. If you are not properly cleaning your lenses, not using solution on them, using lotion laden soap on your hands before inserting your contacts, or not replacing your contact lenses at the proper pre-determined times, then these are all issues that can contribute to the level of discomfort that you are experiencing.
What Does A "BC" Refer To?
A "BC" is shorthand for "Base Curve". This is a generic measure of the curve of your contact lens. The BC rating will help determine what sort of contact lens you should purchase. The higher the number of the BC, the flatter the curve of the lens.
