Dry eye occurs when your eyes aren’t producing enough tears, or when the tears they do make aren’t working as they should. Tears do more than you might think—they keep the surface of your eyes moist, help wash away debris, and provide essential protection. When this system isn’t working properly, your eyes may feel gritty, irritated, and occasionally blurry.
Vision Test: A Quick Snapshot
ou pass, you may be told your vision is “normal”—but this only scratches the surface of your overall eye health.
A vision test (or vision screening) is designed to assess how well you can see. These are usually brief exams that check for common issues like:
- Nearsightedness (myopia)
- Farsightedness (hyperopia)
- Astigmatism
- Basic eye alignment
These screenings typically involve reading from an eye chart and may be administered by school nurses, DMV employees, or general medical providers. If you pass, you may be told your vision is “normal”—but this only scratches the surface of your overall eye health.
Limitations of a Vision Test
- It doesn’t check the internal structures of your eyes
- It won’t detect early signs of serious eye diseases like glaucoma or macular degeneration
- It doesn’t assess how your eyes work together or how your brain processes visual information
- It may not catch gradual vision changes or subtle issues with depth perception or contrast sensitivity
A vision test can be helpful as a first screening tool, but it’s not a substitute for a full eye health evaluation.
Comprehensive Eye Exam: A Full Health Checkup for Your Eyes
A comprehensive eye exam goes far beyond a basic vision screening. It’s a detailed evaluation of your vision and overall eye health, performed by a licensed eye doctor using specialized tools and techniques.
What’s Included in a Comprehensive Eye Exam?
Every practice may vary slightly, but at Center for Excellence in Eye Care, a typical comprehensive exam includes:
1. Patient History
We begin by discussing your medical history, lifestyle, family eye health, and any symptoms you may be experiencing.
2. Visual Acuity Testing
This is the familiar eye chart test, but it’s only the starting point.
3. Refraction Assessment
This helps determine your exact eyeglass or contact lens prescription.
4. Eye Movement and Coordination
We check how your eyes move, focus, and work together. Poor coordination can cause headaches or difficulty with reading, even if visual acuity is good.
5. Slit-Lamp Examination
A microscope with a bright light allows us to examine the front parts of your eye, such as the cornea, iris, and lens, for abnormalities or signs of disease.
6. Intraocular Pressure Test (Tonometry)
This painless test checks for elevated eye pressure, which can be a sign of glaucoma.
7. Retinal Examination (Dilated Eye Exam)
Using special drops to dilate your pupils, we examine the back of the eye—your retina, optic nerve, and blood vessels—for signs of diabetic eye disease, macular degeneration, and other conditions.
8. Additional Tests
Depending on your age, risk factors, or symptoms, we may conduct additional tests, such as retinal imaging, visual field testing, or optical coherence tomography (OCT).
Why a Comprehensive Exam Matters
Even if you feel your vision is fine, many eye diseases develop silently and gradually, with no noticeable symptoms in the early stages. Conditions like:
- Glaucoma
- Diabetic Retinopathy
- Age-related Macular Degeneration
- Cataracts
These issues can all cause permanent vision loss if left undetected. A comprehensive exam is the best way to identify risks early and take proactive steps to protect your eyesight.
