Frequently Asked Questions about Optometry and Vision Care

What You Must Know About Eye Exams:

Our doctors can best decide which tests to perform if you start the appointment by sharing any vision problems you have noticed. Be sure to mention if you have having trouble with headaches, eye fatigue, double vision, tunnel vision, dry eyes, sensitivity to light or other problems.

Visual acuity test:

To measure how clearly you see at a distance, you will be asked to identify letters of various sizes, typically positioned 20 feet away.

Refractive Assessment:

This test helps our doctors determine the right prescription for your glasses or contact lenses. You look into a mask-like device called a phoropter, which holds lenses of various strengths. As you focus on an eye chart, your doctor will flip two lenses into your view and ask if the letters are more or less clear. This allows your doctor to pinpoint the power that gives you the best possible vision.

Pupil size and Reactivity Test:

Your doctor will shine a light into each pupil to see whether both pupils are the same size and contract normally. Pupil problems can be a warning sign of high blood pressure, multiple sclerosis, glaucoma or neurological problems.

Eye Movement Exam:

As your eyes move up and down the doctor checks whether your eyes are properly aligned. This test screens for a disorder in which eyes do not move together when focusing on an object.

Visual Field Exam:

There are several ways to test your peripheral vision, but they all involve covering one eye and staring straight ahead with the other. You may watch a screen as dots of light flash and you will press a button each time you see a dot, enabling a computer to map your field of vision. The test detects blind spots due to glaucoma, a stroke or other ailments.

Slit Lamp Exam:

A slit lamp is a microscope with a thin beam of light, used to examine the front of each eye, including your iris (colored portion), sclera (white area), eyelids, lens, and cornea, under magnification. The doctor may then use special eye drops to dilate your pupils and repeat the exam to view the retina. The test checks for cataracts, macular degeneration, diabetic complications, corneal scratches or infections and chronic dry eye. After the exam, your eyes will be more sensitive to light for a few hours, until the dilating drops wear off.

Corneal Staining Test:

This test looks at the smoothness of your cornea. Your doctor places a drop of orange dye on the surface of your eye and will then look at your eye with a microscope that emits blue light. This test can be given to someone who's had an abrasion, an infection, dry eyes or blurred vision.

Glaucoma Test:

This test, also known as tonometry, gauges the pressure inside your eyes, which goes up if you have glaucoma. The doctor uses special drops to numb your eyes and using a little probe on the slit lamp, the doctor gently presses on each cornea to measure eye pressure. It doesn't hurt and the drops wear off in about 20 minutes.

Anatomy Of An Eye:

To better understand vision problems, eye diseases and eye exams, it can be helpful to get an anatomy refresher. Here's a quick overview of the different parts of the eyes:

  • Cornea – the surface of your eye, helps to refract light on your retina
  • Pupil – the dark circle at the center of your iris that allows light to enter the retina
  • Lens – helps to refract light on your retina
  • Iris – the colored part of your eye that controls the size of the pupil and the amount of light that is focused on the retina
  • Sclera – the white part of your eye
  • Optic Nerve – connects your retina to your brain
  • Retina – light-sensitive tissue along the inner surface of your eye

Testimonial

Family of 4 that recently moved to the area and we are so thankful to have found such a wonderful office!! One of the hardest things when relocating is finding new doctors, but this was an easy one. The staff and Dr.'s are absolutely wonderful. From the very first phone call to the last check out, everyone in the office went above and beyond to make sure that our care and needs were being met. We have 2 younger children and they loved their office visit. We were able to get appointments right away and all of us were seen at the same time, such a stress taken off our shoulders with that one!! Thank you again to such an amazing office, so very thankful we found you!!!
