A prescription for eyeglasses or contact lenses is good for only as long as it’s giving you maximum visual improvement. Exactly how long that is will depend, because everyone’s eyes and vision change at different rates. What we know for sure is that over time, your visual needs will evolve and your prescription will need to keep up. At Today’s Vision, we want you to be aware of the symptoms that indicate you need a new prescription and encourage you to call us for an examination at our Humble eyeglass store when you are experiencing one or more of them.

Some of the symptoms of needing a new prescription will mirror the symptoms that made you seek out your eyeglasses or contacts in the first place. This is to say that as your prescription becomes less effective, the same issues will begin to resurface. So, if you are nearsighted then you might discover that you are suffering with headaches due to eyestrain or blurred vision when trying to focus on objects in the distance. Or perhaps you are having difficulties with driving at night. If you are farsighted, then you could be finding it hard to read or work at your computer. These symptoms are occurring because your contacts or eyeglasses have become insufficient for your current level of vision correction. But it can also be as simple as realizing that you are not seeing with the same clarity that you were getting when your prescription for corrective lenses was first filled. If you notice any of the above signs, call us and schedule an eye exam at our Humble eyeglass store.
In order to determine what your new prescription will be, our eye doctor, Jay S. Pravda, O.D., will test your visual acuity the same as in any complete eye exam. As a matter of fact, the very best way to stay on top of your lens prescription is to be sure and have an eye exam at our Humble eyeglass store every year. In addition to ensuring that your contacts or eyeglasses are current, a yearly eye exam also lets you be screened for common eye diseases, most of which do not have symptoms in their early stages.

The need for prescription glasses or contact lenses depends on the shape of your cornea. A person with perfect vision has corneas that are perfectly round, or at least near perfect. Any change in shape results in a vision impairment. If your cornea is too rounded, then you may have myopia or nearsightedness. If your cornea is too flat or not rounded enough, then you are farsighted or have hyperopia. Astigmatism is when the shape of the cornea is irregular or asymmetrical. All of these changes in corneal shape affects how light passes through the cornea to the retina located at the back of the eye that registers images. Any distortion of the cornea will affect how light passes through the eye and results in objects at different distances appearing blurry. Glasses and contact lenses purchased from our Humble optical store aim to make up for any difference in the inherent shape of your cornea so light passes through the eye as it is meant to, resulting in clear, crisp vision. Here at Today’s Vision, we can provide you and your family with comprehensive eye exams that will help determine whether glasses or contacts are better for you and your lifestyle. Glasses and contacts refract light differently though they both make up for the lack or excess of curvature in your cornea.
Glasses rest on the bridge of the nose and sit at a small distance from the eye, whereas a contact lens rests directly over the cornea itself. Because of their differing proximity to the eye, glasses and contact lenses require different prescriptions. Each one is designed to give you the best vision. Visit us at Today’s Vision in our Humble optical store today to see which vision correction method is best for you.
