How Long to Wear Sunglasses After Dilation?

Eye dilation is a common procedure that allows your optometrist to examine the back of your eyes to check for any potential health issues. However, this procedure can leave your eyes more sensitive to light, making sunglasses a necessary accessory. This article will delve into the details of how long you should wear sunglasses after dilation and why it’s important.

Understanding Eye Dilation

Before we discuss the duration of wearing sunglasses post-dilation, it’s crucial to understand what eye dilation is and why it’s done.

What is Eye Dilation?

Eye dilation is a procedure where an optometrist uses special drops to widen, or dilate, your pupils. This dilation allows more light to enter your eyes, providing a clear view of the back of your eyes, including the retina, optic nerve, and blood vessels.

Why is Eye Dilation Done?

Eye dilation is a critical part of a comprehensive eye exam. It helps your optometrist detect various eye diseases and conditions early, such as diabetes, high blood pressure, macular degeneration, retinal detachment, and glaucoma.

The Need for Sunglasses Post-Dilation

After your eyes are dilated, your pupils remain wide open for several hours, making them more sensitive to light. This sensitivity can cause discomfort and difficulty in focusing on bright lights. Here’s where sunglasses come into play.

Protection from Sunlight

Sunglasses act as a shield, protecting your dilated eyes from the harsh sunlight. They reduce the amount of light entering your eyes, providing relief from the glare and making it more comfortable for you to be outside.

Preventing Strain and Discomfort

The increased light sensitivity can cause eye strain and discomfort. Wearing sunglasses can help alleviate these symptoms by reducing the brightness and glare that your eyes have to deal with.

How Long to Wear Sunglasses After Dilation

The duration for which you need to wear sunglasses after dilation depends on how long the effects of the dilation drops last.

Typical Duration of Dilation

Typically, the effects of dilation drops can last anywhere from 4 to 24 hours, depending on the type of drops used and how your body reacts to them. Most people find their vision returns to normal within 6 to 12 hours.

Wearing Sunglasses: A Rule of Thumb

As a general rule, you should wear sunglasses whenever you’re outside until the effects of the dilation drops wear off and your pupils return to their normal size. This could mean wearing sunglasses for the rest of the day following your eye exam.

Tips for Managing Light Sensitivity Post-Dilation

Apart from wearing sunglasses, here are some additional tips to manage light sensitivity after an eye dilation procedure:

1. Use Protective Eyewear Indoors

If you’re finding indoor lights too bright, consider wearing sunglasses indoors as well.

2. Limit Screen Time

Try to limit your screen time as much as possible until your eyes return to normal. If you must use a screen, lower the brightness and take frequent breaks.

3. Arrange for a Ride

Your vision can be blurry after dilation, making it unsafe to drive. It’s best to arrange for someone else to drive you home after your appointment.


Eye dilation is a vital part of an eye exam, but it can leave your eyes sensitive to light. Wearing sunglasses post-dilation is a simple and effective way to protect your eyes and reduce discomfort. Remember, the duration of wearing sunglasses can vary based on the dilation drops used and your body’s response. When in doubt, it’s always best to consult with your optometrist.
