Exam Duration

Your exam will likely last 1-2 hours and may include dilation of your pupils.

Glaucoma Testing

We routinely assess your eye pressure during eye exams by “applanation,” as increased eye pressure may be the first sign of glaucoma. Applanation, as opposed to an air puff, is a direct and very accurate measurement of your eye pressure taken with a blue light and a special dye. There is no “puff.”

Risk factors for glaucoma include:

  • Age
  • Aberrations in nerve fibers of your retina
  • Appearance of your optic nerve
  • Changes in visual field
  • Eye pressure
  • Family history of glaucoma
  • Race

Ocular Motility

We use several methods to assess proper ocular motility or eye movements such as: do your eyes move together? Strabismus is a common childhood motility problem, but misalignment can occur in adults too. Patients with thyroid disease or orbital trauma can often have ocular motility problems.


Refraction is the actual determination of your eyeglass prescription. Using a phoropter and retinoscope, we can accurately measure your degree of nearsightedness, farsightedness, and determine any degree of astigmatism. Refraction is an important part of any comprehensive eye examination as it can be affected by a variety of eye diseases, such as diabetes, cataract, dry eye or keratoconus.

Refraction Fee Notice

There are two parts to your eye examination, which are billed separately.

  • The first charge includes the fee for the doctor to evaluate the health of your eyes. This charge is billable to your insurance company, and also to Medicare.
  • The second (vision) portion of your exam is called a “refraction,” which is a test performed to determine the best corrective lenses to be prescribed for each eye.

Although a refraction is a very important vision test, it is considered a non-medical procedure. Medicare and most insurance plans do not pay for this service, the fee of which is now $70.00, effective March 1, 2023.

We request that payment for this service be made at the time of your visit. Thank you.

Visual Acuity Testing

Visual acuity testing, also known as reading the eye chart, is one of the first tests we will perform at your eye exam. Your visual acuity, how well you see with or without glasses, can help us determine if you need prescription lenses.

Slit Lamp Examination

A slit lamp is a specialized binocular microscope that allows us to examine the eye and its structures under high magnification. The slit lamp examination, in conjunction with pupil dilation, allows your eye doctor to look at the structures of the eye.

The slit lamp examination evaluates the following:

  • Lids and lid margins – blepharitis, meibomitis are common
  • Tear film – any evidence of dry eye?
  • Conjunctiva – clear, vascular tissue covering the sclera and inner eyelids
  • Cornea – corneal scars and infections can decrease vision
  • Sclera – the white exoskeleton of the eye
  • Anterior Chamber – fluid filled space behind the cornea in front of the iris
  • Iris – the colored structure that controls the amount of light in the eye
  • Lens – cataracts, which are easily diagnosed with the slit lamp
  • Vitreous – bleeding, infection, floaters are easily seen with your eyes dilated
  • Optic nerve – evidence of glaucoma may first show up here
  • Retina – bleeding, retinal tears can be detected when your pupils are dilated
