Visiting an optometrist for corrective lenses is vital if someone has poor eyesight. People who purchase cheap pairs of reading glasses in stores may not realize that these are not going to truly help them see more clearly. In fact, wearing glasses that do not have the corrective lens a person needs can damage their eyesight further. Corrective lenses are customized visual aids designed to enhance the weaker aspects of an individual's eyesight.
Corrective lenses address refractive problems such as nearsightedness, farsightedness, presbyopia, and astigmatism. Glasses or prescription eyewear rest on the bridge of the nose a short distance from the eyes. If you are interested in learning more about corrective lenses or want to enhance your vision, give us a call today.
According to the World Health Organization, there are about 253 million people around the globe with some form of vision impairment. Most have preventable and treatable conditions. One of the most effective ways to improve a person's vision is by using prescription lenses.
Even people with 20/20 vision may benefit from wearing corrective lenses. Eyewear can block the blue light from electronic devices, which can lead to eye strain when staring at a screen for long periods of time. A person can develop vision problems when light enters the eyes and does not focus on the proper location in the retina.
The light might shoot too far back in the retina, as is the case with farsightedness. In other cases, the light might be too far in front of the retina, leading to nearsightedness. A person might also have a vision problem if they have a cornea with an abnormal shape. The abnormal shape prevents light from properly focusing on the retina.
A corrective lens has a unique curvature, which is the prescription the optometrist provides for the patient. The curvature focuses the light entering the eyes on the proper part of the retina, leading to clearer vision.
There are two main types of corrective lenses: convex and concave. These are also called plus and minus lenses, respectively. A third option is known as compound lenses, which is a combination of both. Our team will take the time to examine the patient and determine which option will work best for their needs.
The surface of a convex lens bulges outward. These types of lenses are sometimes known as converging lenses since they bring parallel rays of light together and focus them on a single location known as the focal point.
Convex lenses are typically a component in devices such as telescopes and binoculars. An optometrist may use a convex lens to treat farsightedness.
Concave lenses are the opposite of their convex counterparts. The surface of the lens curves inward, making parallel rays of light diverge from one another. Concave lenses are sometimes called diverging lenses for this reason. These types of lenses help to treat nearsightedness.
It is possible to combine concave lenses with convex lenses to create compound lenses.
Other types of lenses include:
The optometrist will educate the patient about which type of lenses are best for them after their vision has been evaluated with a comprehensive eye exam.
Think you need corrective lenses? Here are answers to some of the inquiries you might have:
An optometrist is a medical care professional who specializes in eye and vision care. An ophthalmologist is a medical doctor who specializes in the diagnosis, treatment, and prevention of diseases and disorders of the eye.
Yes, you will need a prescription from an optometrist or ophthalmologist to get corrective lenses.
It is generally recommended that you have your eyes checked every two years. However, if you have a family history of eye disease or are at increased risk for developing eye problems, you may need to have your eyes checked more frequently.
There are two main classes of corrective lenses: glasses and contact lenses. Glasses are worn on the outside of the eye, and contact lenses are worn on the eye's surface. Both types of corrective lenses can correct nearsightedness, farsightedness, and astigmatism.
The type of corrective lens that is best for you will depend on your individual needs and preferences. Your optometrist or ophthalmologist can help you choose the best type of lens for you.
