Eye exams are an important step for keeping vision and eyesight healthy. By not seeing a professional optometrist at least once every two years, you can increase the chance of undiagnosed conditions getting worse over time. An eye exam consists of a number of tests that are administered to evaluate a patient's vision and to diagnose eye diseases.
Eye exams are offered at Vision Corner Uptown in Houston and the surrounding area. The tests we conduct during an eye exam can include various instruments and charts. Each test helps to evaluate a specific aspect of the patient's vision or eyes.
To receive an eye exam and determine the health of your vision, give us a call today at (713) 357-6195.
The importance of eye exams
Eye examinations make it possible to detect problems with the eyes and overall vision as early as possible. It also gives us a chance to analyze the patient's vision, correct vision problems and educate patients on how to take proper care of their eyes.
There are a number of factors that determine how frequently each person will need an eye exam, such as the patient's family history, age and overall health. The guidelines for how often a person needs an eye exam include:
1. Patients who are 3 years old and younger
An optometrist might look for signs of common eye issues, such as crossed eyes and lazy eyes. Parents/guardians should bring their child in for their first comprehensive eye exams before they reach the age of five.
2. Children and teenagers
A child's vision should receive an evaluation before they start grade school. If there are no signs of vision problems after the first test and there is no history of vision-related problems in the family, the child should only need to come in for an appointment every one to two years.
People who are healthy without any signs of vision problems should get an eye examination once every five years in their 20s and 30s. The number of times per year can vary with each patient. Having a specific condition or vision problem can impact the number of visits.
What to expect during an eye examination
With a scheduled eye exam, patients will be able to plan out their exam months in advance instead of the last minute. This way, patients will be more relaxed and less stressed upon arrival. Along with that, patients can call and schedule a last-minute appointment when they need to treat a sudden illness or eye issue.
Eye exams typically include:
- Filling out a form about the patient's current condition and medical history
- Administering tests by the optometrist to evaluate the patient's vision
- Tonometry test to test for glaucoma
- Dilating the patient's eyes with eye drops to evaluate the front and insides of each eye
The various types of eye exams
During an eye exam, we will conduct a variety of tests to measure the strength of the vision along with the health of the eyes. Even something as simple as straining to see at a distance can be the sign of a serious medical condition.
Eye muscle test
An eye muscle test can analyze the muscles in charge of eye movement. This test is fairly simple as we will examine the patient's eye as they look at a moving object.
Visual acuity test
This test evaluates how clearly a person can see. We will ask the patient to call out letters on a Snellen chart or a screen, testing each eye individually. This will evaluate both near and farsightedness.
A refraction assessment reviews the type of lens prescription that will best address the patient's vision issues. This test will involve a computerized refractor or a retinoscopy. The patient looks through a machine that contains different lenses while calling out letters from a chart.
Visual field (perimetry) test
This is used to determine if the patient has issues seeing out of the sides of their eyes. It can include:
- A confrontation exam
- Manual testing
- Automated perimetry
Color vision testing
This test is done to evaluate how well the patient's eyes pick up colors.
This is used to analyze the back of a patient's eyes. We will review areas of the eye such as the blood vessels that feed the retina, the optic disc and the retina. The patient's pupils are dilated to prevent them from shrinking when we shine a light inside the eyes to examine them.
