than having 20/20 vision or needing glasses 

An eye exam not only tests for visual impairment, but also for other underlying health issues. Even if you do not feel like you need glasses, many asymptomatic conditions exist that can be identified early on with an eye exam. A complete eye exam involves a series of tests designed to evaluate your vision and check for eye diseases. Each test during an eye exam evaluates a different aspect of your vision or eye health.


This is how the power of eyeglasses is calculated. This is what will tell the doctor if you area nearsighted, farsighted, have astigmatism, among other things.

"Which is better, 1 or 2?"

External Ocular health

The "external" part of your eye includes your eyelids and eyelashes, cornea, iris, and lens of your eyes.

A slit lamp must be used to properly assess those structures. Only eye doctors offices have this instrument.

Internal Ocular health

Patients with glaucoma, retinal tears or detachments, diabetic retinopathy, macular degeneration, freckles (nevi) and even tumors more often than not, have 20/20 vision and never have any pain.

The only way to find out is by having a retinal evaluation.


The refraction is the base for all of your glasses prescriptions - single vision, progressive, computer - as well as starting point for contact lenses.


The phoropter is the most commonly used instrument for refraction. This can obtain far and near prescriptions.

Trial Frame - "free space"

Best way to determine if new prescription is too strong/"off" as well as demonstrating vision through the new prescription.

Trial Frame - near vision

The best way to determine the prescription for reading or computer glasses is by having the patient look at their phone or laptop and not just at a paper chart.

External ocular health

The slit lamp is used to determine if the patient has "pink eye", if they scratched their cornea, how bad their dry eyes are, etc

Corneal abrasion

"A scratch on the clear, protective "window" at the front of the eye called the cornea".

Giant Papillary Conjunctivitis

Occurs when the inside of the eyelid gets red, swollen, and irritated. Without GPC, the inside of the eyelid is very smooth.

Superficial Punctate Keratitis

Caused by death of small groups of cells on the surface of the cornea. Often seen with dry eye syndrome.

Internal ocular health

We recommend ALL patients have a thorough examination of their retina at every year. Without a Optomap or dilated exam, the doctor cannot fully assess the health of the back of your eyes.

Healthy retina

The retina is composed of the inner neural or sensory layers and the outer pigment epithelium.

The normal retina is essentially transparent, although it does absorb a quantity of light passing through it.

Various eye conditions

Some of the possible eye conditions we check for are: macular degeneration, retinal holes, retinal detachments, hypertension and diabetic retinopathy.
Benign or malignant (cancerous) nevi or "freckles" of the back of the eye can also be found just like freckles on your skin.

Retinal detachment

A retinal detachment is the separation of the sensory retina from the Retinal Pigment Epithelium (RPE) (outer segments of the photoreceptors).
The sensory retina in the periphery is thin and relatively weak and thus is susceptible to full thickness breaks.

Early detection could help save your vision or your life.

Dr. Miller is thorough and compassionate. She discovered the indicators in my wife’s eye that was later diagnosed as a brain tumor. We wouldn’t have caught it without her. We’ll be patients for life!



  • No blurred vision
  • No light sensitivity
  • Takes 2-3 minutes 
  • Permanent record for future comparison
  • You can see your retina!
  • Blurred  near vision for 4-8 hours
  • Light sensitivity for 4-8 hour
  • Longer office visit waiting for dilation drops to work
  • No permanent digital record of the retina
  • Only the doctor can see the retina

I don't think I need it because...

...... I had it done last year

A lot can happen in 12 months. The retina doesn't wait 2 years to start developing eye conditions...it can happen a month after your retinal evaluation. Early detection is key!

...... I'm too young

Most eye diseases are not related to age. Glaucoma and macular degeneration are 2 of the few which do mainly effect the older population. Other than that, every age is at risk for most eye diseases.

...... I'm healthy overall

Many eye diseases have absolutely no correlation to overall health. Retinal holes, detachments, glaucoma, certain retinal hemorrhages and tumors to name a few.

Dr. Miller prefers Optomap retinal photos over dilation because:

  • It allows for enlargement (zooming) of image to see more detailed view of the retina 
  • It takes just a few minutes start-to-finish, a much shorter office visit than if dilation is performed
  • You leave the office with vision intact, rather than with light-sensitivity and blur
  • Creates a permanent record of your retina for future comparisons–we can compare this year’s image to next year’s image—side by side
  • Can be reviewed by other doctors, if necessary
