Nearsighted vs. Farsighted
Nearsightedness and farsightedness are two of the most common vision problems in the U.S. If you are nearsighted, it means that you can see objects that are close but things that are farther away appear blurred. If you are farsighted, it means that you can see things in the distance clearly, but things that are close appear unfocused. Dr. Lan O’Donnell and Dr. Heidi Gonzalez are eye doctors at O’Donnell Eye Institute in Santa Rosa Beach, FL, where they provide glasses for nearsightedness and farsightedness.
Santa Rosa Beach residents who are nearsighted, or myopic, have difficulty seeing objects in the distance. For example, you will have no problem reading a newspaper but will find it hard to see your TV screen clearly. This condition is either due to the fact that your eyeball is longer than usual, or your eyes’ lenses are too curved, which makes it difficult for your retina to focus light.
Farsightedness, or hyperopia, occurs if your eyeball is too short or your eyes’ lenses are not curved sufficiently for the light to focus properly. This causes close vision to be blurred. This condition is less common than myopia and can be more difficult to detect in basic vision tests.
Changes in your Vision
Even if you have had perfect vision throughout your life, your vision may begin to change as you get older. This is not uncommon. Changes might take place when you reach your 40s or 60s. Fortunately, eye problems such as nearsightedness and farsightedness are easily treatable with corrective lenses in glasses or contact lenses.
If you live in Santa Rosa Beach and you are having problems with your vision, call Dr. O’Donnell and Dr. Gonzalez at (850) 622-4000 to schedule an appointment for a vision test.
Having a yearly physical or dental cleaning may be a normal part of your life, but what about eye exams? Unless you wear glasses, you may not regularly visit an optometrist. However, scheduling an eye exam can be instrumental in detecting eye problems such as glaucoma, which can cause vision loss or total blindness.
Drs. Lan O'Donnell and Heidi Gonzalez frequently diagnose and treat glaucoma at O'Donnell Eye Institute in Santa Rosa Beach, FL, and they want to make sure their patients are aware of the warning signs of glaucoma. Although there are several types, this article will concentrate on the two main classifications: primary open-angle glaucoma (POAG) and angle-closure glaucoma (ACG).
Behind both of your eyes is an optic nerve that sends visual signals to the brain for processing. Glaucoma causes pressure to build up behind the eyes and damages the optic nerve. Anyone is at risk for developing glaucoma, although people over age 60 and those with a family history are more susceptible. The causes of glaucoma are largely unknown.
Changes in the way you see often accompany ACG. Many of our patients at O'Donnell Eye Institute report a new haziness or blurriness. When looking at bright lights, some people notice rainbow-like halos around them. A few people will have a sudden loss of sight. The visual disturbances with POAG are more subtle and can affect the peripheral, or sides, of your visual field. Although these symptoms can be indicative of other conditions, any unexplained changes in your vision should be evaluated by your Santa Rosa Beach eye doctor at once.
Because of the pressure that has to build up behind the eyes, those with glaucoma may experience a new and very uncomfortable headache or eye pain. It can even cause nausea or vomiting due to a response called the oculoabdominal reflex.
The idea that you are developing irreversible damage to your eyes without your knowledge is a scary one, but this can be a reality for those with POAG. By the time POAG begins to noticeably affect vision, it is often advanced and has caused significant damage to the optic nerve. The good news is that by scheduling yearly eye exams with your Santa Rosa Beach optometrist, both types of glaucoma can be detected and treated in their early stages.
