Eye Exam Q & A

Why do I need to go for an eye exam?

There are significant benefits to be gained from attending regular eye exams. Your provider can see any early signs of serious conditions such as:

In addition, they can treat common issues affecting the cornea, which provides a barrier against dirt, germs, and particles, but is prone to injury, allergies, keratitis, and dry eye.

Your provider can also test your eyesight and prescribe corrective lenses and glasses for myopia (nearsightedness), hyperopia (farsightedness), and astigmatism.

At Ophthalmology Physicians & Surgeons, PC, team members include both ophthalmologists and optometrists, so you can be sure of receiving an outstanding level of care whatever your needs.

What happens during my eye exam?

A comprehensive eye exam generally lasts for between one and two hours, depending on whether you need any specialist tests. Standard tests include:

Visual acuity test

Your provider asks you to try and read lines of letters from a chart on the wall. This test identifies whether you need corrective glasses or lenses.

Refraction test

Your provider uses a selection of various lenses to measure how well your eyes can focus light. People with nearsightedness, farsightedness, and astigmatism all have problems in the anatomy of their eyes that prevents them from being able to focus properly.

Dilation test

Your provider examines your eye using a special magnifying lens. Looking through this lens, they can assess the health of your retina, macula, and optic nerve, and detect any signs of glaucoma or diabetic retinopathy.


Your provider may use a tonometer, which is an instrument that they press against your eyeball, or a puff of air to measure the pressure inside your eyeball.

Visual field test

Your provider asks you to view objects or images using your peripheral vision to check for signs of glaucoma.

How often should I have an eye exam?

The interval between eye exams is something your provider can advise you on. If you need prescription lenses, your provider is likely to recommend an annual eye exam, but every patient has different needs. If you have diabetes or there’s a history of glaucoma in your family, for example, you may need to go more frequently.

If you have any problems with your eyes or failing vision in between your regular exams, make an appointment for a checkup. Call Ophthalmology Physicians & Surgeons, PC or schedule an appointment online today.
