Comprehensive eye exams should occur early in life to ensure the eyes have started developing properly. Ongoing eye exams held regularly are equally important. Many eye diseases and vision changes can occur without any warning signs.
During a comprehensive eye exam, Dr. Pairolero and Dr. Langhorst will use eye charts to measure how sharp your vision is. The most common example of an eye chart is the Snellen eye chart. Though there are many variations of the Snellen eye chart, most will show 11 rows of capital letters.
You will be asked to find and then read the smallest line of text that you can see. The standard used for visual acuity is 20/20. This is the fourth line from the bottom. If you can read either of the bottom two rows, your visual acuity is better than most people.
At EyeCare Associates of Haslett & Perry, we believe in a thorough eye exam. This means we also check for color vision deficiencies and test your eyes to see how they work together. To ensure your eyes are healthy, we recommend seeing an eye doctor for your comprehensive eye exams on a regular basis.
What Happens During an Eye Exam?
When you call to make an eye appointment at EyeCare Associates of Haslett & Perry, be prepared to describe any current vision problems you may have. You should also ask if the eye exam will affect your vision temporarily.
If it will, you will need someone to drive you home. You may also want to ask about the cost of the exam, if your insurance plan will cover any of the cost, and how payment is handled. Items that you may want to prepare for your eye exam include:
- Visual history review with your eye doctor of any previous eye diseases and eye health
- Be sure to remove any eye makeup before your eye exam
- Be sure to bring your medical health and eye insurance information.
- New patients are encouraged to print, and fill out medical forms
- Be prepared to discuss any health problems and/or allergies.
During your eye exam, you will undergo several tests and procedures to examine your eyes. Your eye exam will usually begin with an external examination. This is referred to as a visual acuity test. During this test, you may need to read an eye chart. Visual acuity tests focus on the sharpness of your vision.
There are also more specialized tests for specific regions and functions of the eyes. These are for pupil function, visual fields, intraocular pressure, and more. Children are evaluated for eye muscle coordination problems. These can cause difficulty in school or make it hard to concentrate.
How Long Does a Comprehensive Exam Take?
A comprehensive exam involves several tests and may take an hour or longer to complete.
Who Should Have an Eye Exam?
Everyone should have an eye exam, even when their vision is perfect.
What Are the Signs that You Need an Eye Exam?
Common signs that you may need an eye exam include:
- Eye pain or corneal scratching: The cornea is one of the most sensitive parts of the eye. This makes a very small corneal abrasion extremely painful. Even though it may be a tiny scratch, it can feel much larger and seem as if something bigger is in your eye. You may sometimes hear this described as a foreign body sensation.
- Blurred vision: When it gets harder to see things clearly, this could be due to conditions like dry eye syndrome, cataracts, or glaucoma.
- Poor peripheral vision: The presence of spots in your peripheral vision or loss of vision may mean you have a retinal detachment.
- Dry eyes: Dry eye can be a result of several things. This includes seasonal allergies, medications, spending too much time in front of digital devices, or being exposed to a dry or windy environment. Dry eyes burn, sting, may have discharge, and appear bloodshot.
