Dilating your eye causes the pupil to get bigger so the doctor can better check the Macula and optic nerve health. The picture below shows it best.

To properly dilate your eyes the doctor will put eye drops in your eyes. It can take 15-30 minutes for your pupils to fully dilate. Dilated eyes can last for 4-6 hours on average, though for some people it can last longer. (BrightFocus Foundation brightfocus.org)

How often should I get my eyes dilated?

It is recommended for children and people 40+ to get their eyes dilated every year. People with underlying health conditions such as diabetes and hypertension should also be dilated every year. Everyone else should be dilated every other year. If you're not sure if you should be dilated check with your eye doctor and they will let you know.

Every time you go to the eye doctor for your yearly eye exam you will go through a few pre-tests before you’re seated in the exam room. One of those tests is called autorefraction. This test checks two things:

  1. The first thing it checks is your prescription. While this test is being performed you will see one of a few images- some are of a hot air balloon and some are of a farmhouse. The image will go in and out of focus. From this test we can get a starting point for your prescription and we can work from there to find the best prescription for your eye. Your prescription can be determined without this test, but we do this to help streamline the process.

  2. The second part of this test is the keratometer reading. It reads the curvature of your eye and helps the doctor fit the best contacts for your eyes. It also helps the doctor properly correct the astigmatism.

When you go to the eye doctor, some doctors will perform a test where they blow a small puff of air into your eye to test your intraocular pressure (IOP). This is called non-contact tonometry. Most people don’t like this test because it startles them and it makes their eyes water. Here, at Choice Eye Center, we don’t use the puff test. Instead, we use the icare tonometry, which is much softer than the puff test. Our doctor, along with other experts, believe this test is more accurate for tracking intraocular pressure. The icare tonometry is performed by using a tiny plastic probe bouncing on your eye several times to read the pressure of your eye. It will then calculate the average pressure reading as the final eye pressure results. Most people describe the feeling of this test as a light tickling of the eye.

Another option for finding the IOP that is sometimes used is The Goldman’s Test. In this test the doctor will first numb the patient's eye and then apply fluorescein, which is a dye, that will help illuminate the eye during the test. After the eye is numb, the doctor will turn the blue light on and bring the Goldman probe in contact with the eye. The doctor will then look through the biomicroscope (slit lamp) at the eye to find the correct measurement and record it in your chart. A high pressure will indicate further testing and possibly glaucoma. A low pressure is called ocular hypotony and can cause blurred vision.

Every time you see your eye doctor you should have at least one of these tests done to track changes in your intraocular pressure to ensure that you get proper care quickly. This is just one of the many reasons you should get your eyes checked every year. (Glaucoma Research Foundation, glaucoma.org)
