Comprehensive Eye Exam vs. Contact Exam: What's the Difference?

If you are considering going to The EyeDoctors Optometrists for an eye exam, it's important to understand that all visits are not the same. Making an appointment for a comprehensive eye exam can help determine how healthy your eyes are and if your vision has changed. But if you're hoping to also get contacts to correct nearsightedness, farsightedness or astigmatism, this exam won't be enough.

The last thing you want is to find out the appointment you've scheduled is not what you expected. When it comes to booking a comprehensive eye exam vs. a contact lens exam, here's what you'll want to know beforehand.

Usually, the earlier you catch and treat serious eye conditions, the less likely you are to suffer vision loss. This makes booking an appointment at The EyeDoctors Optometrists all the more important. Common eye diseases that optometrists at The EyeDoctors Optometrists may check for include:

• Glaucoma: This includes a group of eye diseases that can result in vision loss due to optic nerve damage.

• Cataracts: This is caused by a clouding of the lens and could lead to vision loss.

• Age-related macular degeneration: This involves the breakdown over time of a portion of the eye's light-sensitive tissue.

• Diabetic retinopathy: This disease damages blood vessels in the eye and if left untreated could lead to blindness.

You can expect to undergo a variety of tests, depending on what your doctor feels is necessary. To get a better idea, the The EyeDoctors Optometrists optical care team first takes a patient history. Then, they may conduct some of the following tests:

• Visual acuity test: This helps to determine how well you are seeing and usually involves reading letters off a chart on the wall.

• Pressure testing: This checks the pressure of your eye and helps to ensure you are not developing certain diseases, such as glaucoma.

• Visual field test: This test will check your vision for possible blind spots.

• Testing refraction: This test involves finding the lens power needed for you to see clearly.

• Colorblindness test: This will show your doctor if you are having trouble perceiving certain colors.

• Eye dilation: For this, your doctor will administer special eye drops to temporarily expand the pupil. This allows them to see what's going on inside the eye and make sure all the structures are healthy.

• Stereopsis exam: This tests for depth perception.

In the contact lens exam, you can expect an The EyeDoctors Optometrists optometrist to do the following:

• Conduct tests to be sure you don't have any issues that could interfere with successful lens wear.

• Measure both your pupils and irises to make sure the lenses fit well.

• Measure the size and shape of your eye to ensure your lenses fit properly and are comfortable.

• Measure your cornea, the clear outer surface of your eye, to find the right curvature and size for your lenses. If your eye has an irregular curvature, you may need to be fitted for what's known as a toric contact lens. This can help to compensate for some distortions and provide better vision.

All of this will help your optometrist understand the type of lens and prescription that's best for you. After the initial exam, The EyeDoctors Optometrists will ask you to come back for a follow-up appointment to be certain the prescription is working for you and your lenses fit as they should.
