Does a comprehensive eye 
exam include refraction?
A comprehensive eye exam is a check-up of your overall eye health. It includes tests for sharpness of vision 
(refraction) and other problems that don’t require a specialist, such as pink eye.
A comprehensive eye exam includes a number of tests and procedures to examine and assess the health of 
your eyes and the quality of your vision. But what, specifically, is included in a comprehensive eye exam?
One common procedure that is often included in a comprehensive eye exam is a refraction test. This test 
helps determine your eyeglasses prescription, if you need glasses or contact lenses to correct your vision.
So, does a comprehensive eye exam include a refraction test? The answer is yes – a comprehensive eye 
exam typically includes a refraction test. However, not all eye exams are comprehensive. Depending on 
your specific needs, some tests and procedures may be omitted from your exam.
If you’re wondering if a particular test or procedure is included in your eye exam, be sure to speak with your 
optometrist.The registrar’s guide to eye exams
When you check in for your appointment, you’ll be asked a number of questions to determine what tests and 
procedures you require. Be sure to ask if your optometrist will perform a refraction test. If not, another doctor 
or optometrist will perform the test. Optometrists will perform a refraction test at the time of your first visit 
regardless of the time of year.
HOW TO PREP FOR THE TEST
Refraction tests are usually performed in a clinical setting. This means that you may be asked to remove your glasses before 
you are tested.
In this case, you should be wearing a contact lens or eyeglasses. If you wear glasses, you will need to remove them before 
your test.
A refraction test is most effective when the patient is sitting still without moving their eyes. To be sure, you will need to plan 
your appointment to ensure you have enough time for a full test. The optometrist will ask you to determine the best way for 
you to keep your eyes still and ensure that your eyes are not moving during the test.
You may be asked to sit for a period of time before the test to ensure your eyes are still. You may be asked to look at a 
particular object. This object will be changed for each session. The first time you are tested, the optometrist will ask you to sit 
for a period of time while staring at a single object. This will help the optometrist determine if your eyes are moving.
You may also be asked to repeat a color or pattern that you are asked to look at.You may also be asked to remove your 
contact lens or eyeglasses. If you wear glasses, you may be asked to remove these before you are tested.
Another consideration is to make sure that you have your glasses case handy. You may need to remove your glasses at the 
time of the test.
You may also be asked to remove your contact lens or eyeglasses. If you wear glasses, you will need to remove these before 
you are tested.
What is refraction?
Refraction is the process of bending light as it passes through your eye. Refraction is the 
process of focusing light rays as they travel through the cornea and the lens of the eye. The 
process of refraction is different from the process of vision, which is the process of seeing 
images.
When the refraction is correct, you have good vision, but if you are experiencing blurry, 
distorted, or halos vision, you may need to have an eye exam. Blurb seeing is a variety of 
refraction paradox
A refraction paradox describes how a person can experience blurry vision and yet still have 
good refraction. This has to do with the fact that the eyes have a tendency to focus the 
opposite of what they are actually seeing. You can have good refraction but still be 
experiencing blurred vision. If you are experiencing blurry or distorted vision, it could be due 
to several different causes. You may need to see an optometrist for the following reasons:
A refraction test is the most common vision test used to check the sharpness of your vision. 
The test is used to determine eyeglass prescriptions.
Is refraction included in a 
routine eye exam?
Having a comprehensive eye exam included in your routine eye exam check-up is 
important. You may think that because your eyes are healthy, you don’t need an eye 
exam. However, there are other factors to consider when it comes to having a 
routine eye exam.
If you are experiencing blurred vision with halos, glare, or decreased contrast, you 
may need to have an exam to check for refraction. Refraction is not typically included 
in a routine eye exam, but it is an important part of keeping your eyes healthy.
Refraction is the bending of light as it passes through the cornea and the lens of the 
eye. This bending causes images to be focused on the retina. When the refraction is 
correct, you have good vision.
If you are experiencing blurry or distorted vision, you may need to see an optometrist 
for a refraction test. If you have a refraction test, you will be able to determine if you 
need glasses or contact lenses.

Refraction test
Refraction is the process by which light is focused as it passes through the 
cornea and the lens of the eye. The refraction process is different from the 
process of vision. Vision occurs when light enters the eye and is focused onto 
the retina. The process of refraction is the bending of light as it passes through 
the cornea and the lens of the eye. This bending causes images to be focused 
on the retina.
