Why Do Eye Doctors Dilate Pupils?

You may be wondering what to expect when you visit an eye doctor? There are a few different aspects of a visit you may not understand, such as dilation. Many people find getting their eyes dilated during an eye exam to be annoying. So, why do doctors do this, and is it really necessary? At M-Eye Vision, serving Katy TX, we want our patients to feel comfortable during their visit. Let’s take a look at why our eye doctor may dilate your pupils.

Is Dilation Necessary?

It is important to note, that dilation is not necessary for every visit. You will want to ask if you will be dilated before heading into the optometrist office. Pupil dilation is often done on older patients. As you age, there is a greater chance of developing macular degeneration, cataracts, and glaucoma. A pupil dilation makes it easier to check for such conditions. If you scheduled your appointment because of changes in vision, blurry vision, burning sensations, or pain in your eyes, our eye doctor will need to dilate your eyes to make an accurate diagnosis.

Benefits of Pupil Dilation

When the eye doctor dilates your pupils during the eye exam, it will allow them to view the back of your eye more clearly. This is necessary to diagnose certain conditions, such as:

  • High blood pressure
  • Diabetes
  • Glaucoma
  • Retinal detachment
  • Macular degeneration

What Happens During Dilation?

Our eye doctor will place special drops in your eyes which force the pupils to widen. This allows more light to enter the eye. This may affect your vision or make you sensitive to light for a while after your appointment. If you are very sensitive to dilation, you may want to ask someone to come to the appointment with you.
