Eye Exam Q & A

What are signs that I need an eye exam?

When light enters your eye, the lens behind your pupil focuses that light onto your retina, which sends signals to your brain so you can see. However, if there is an irregularity in your lens, cornea, or the shape of your eye, your eye can’t focus the light correctly, causing blurry vision.

If you notice that your near or far vision is becoming blurry or if you get frequent headaches, you should schedule an eye exam. Other signs that you should have your eyes checked include:

  • Changes in night vision such as increased glare or trouble reading street signs
  • Squinting
  • Having to hold your phone or book closer or further from your face to see it clearly
  • Sensitivity to light
  • Vision disruptions such as floaters, black spots, or flashes of light
  • Red eyes, discharge, or other signs of infection

If you notice any of these symptoms, you should contact Simply Eyes to make an appointment today.

What should I expect during an eye exam?

During your eye exam, the team at Simply Eyes measures your visual acuity — how clearly you see at both near and far distances — and also monitors your overall eye health and checks for signs of eye diseases. Some of the tests you can expect include:

Visual acuity

During the visual acuity test, you read sequences of letters from an eye chart on the wall of the exam room. The letters decrease in size, which helps your optometrist determine if you have a refractive error such as myopia (nearsightedness) or hyperopia (farsightedness).

Ocular motility

Your optometrist also checks how well your eyes can track objects and change focus on different objects.


Your optometrist uses a digital refraction system to identify the prescription for corrective lenses. Preliminary testing provides an estimate while the digital refraction performed by Dr. Bui or Dr. Pham identifies your precise prescription.

Slit lamp exam

Your optometrist uses a slit lamp exam to examine the structures of your eyes, including the lens, iris, cornea, conjunctiva, and eyelids. While you rest your chin against the machine, your doctor looks through the device, which acts like a microscope so they can study your eye in detail.


During the tonometry test, your technician uses a device to measure the pressure in your eye. The machine sends a quick, painless puff of air into your eye and measures your eye’s resistance to the air.

How often should I have an eye exam?

Our doctors recommend an eye exam at least once a year, even if you do not wear corrective lenses. Prescriptions for eyeglasses and contacts are valid for a year, so you should have an annual eye exam to determine whether you need to update your prescription.
