What Should People Avoid Doing After Eye Dilation?

September 09, 2024

According to a report from the American Optometry Association, optometrists perform an estimated 88 million comprehensive eye exams annually. Most eye exams require patients to have their eyes dilated, which ensures that the eyes can be fully checked for diseases or abnormalities.

Key Takeaways

Dilating eye drops relax the eye muscles and enlarge the pupils. This allows your eye doctor to have a clear view of the back of your eye. They are then able to detect signs of eye disease or other abnormalities.
It takes between 20 to 30 minutes for the eyes to dilate. The effects, such as light sensitivity and blurry vision, take four to six hours to wear off.
When you get your eyes dilated, you should avoid driving, the sun, and digital screens.

Dilation is a safe and routine procedure, though it can have some temporary side effects. Keep reading to learn more!

What Is a Dilated Eye Exam?

A recent report from the American Optometry Association suggests that 85% of all eye exams are performed by optometrists. At your next comprehensive eye exam, your doctor may dilate your eyes using special drops. This allows your doctor to view the whole eye, including the nerves and blood vessels in the back.

How Does Pupil Dilation Work?

Your optometrist will likely apply two types of dilating drops, the first to enlarge the pupils and the other to relax the eye muscles.

Your pupil regulates the amount of light that can enter the eye. It will get smaller when light increases and larger when light decreases. This ensures that you can comfortably see in both bright light and mild darkness.

However, contrary to popular belief, the pupil itself doesn't grow or shrink. Instead, its size is regulated by the muscles in your iris.

How Does Dilation Affect Your Vision?

Once the drops are applied, it will take between 20 to 30 minutes for the pupils to fully dilate. After that, your eye doctor will be able to have a clear view of the back of your eye. This allows them to fully screen your eye for any sign of disease or abnormality.

The effects of eye dilation can last between four to six hours or longer. This can be affected by a variety of factors, including age, eye color, and eye drop formula.

During this time, you may be highly sensitive to bright light and experience blurry vision. However, these effects are temporary. To ease any discomfort and protect your eyesight, be sure to avoid bright lights and straining your eyes.

What Not to Do After Eye Dilation

Though eye dilation is a standard and safe procedure, it can cause you to experience some side effects. Be sure to avoid the following if you will be heading in for an eye exam.

#1. Avoid the Sun

Eye dilation typically causes the pupil to let in more light. Try to limit your time outdoors, as the sun's bright lights can cause eye strain, general discomfort, and UV damage. Wear sunglasses on the way home from your appointment to protect your eyes from the sun's harmful UV rays.

#2. Don't Drive

Because eye dilation can cause fuzzy vision and eye sensitivity, it is not recommended to drive after an eye exam. Be sure to take a friend or family member with you to your appointment so that they can give you a ride home.

#3. Avoid Digital Screens

After eye dilation, your eyes may have trouble focusing on close objects. Cellphones, e-readers, or tables require your eyes to focus on fine print and small fonts, which can end up appearing rather blurry. The bright light emitted by electronic screens can also cause eye discomfort.

#4. Avoid Rubbing Your Eyes

Rubbing your eyes after dilation can cause irritation and damage. If your eyes feel dry or itchy, use artificial tears as directed by your optometrist. Take a few hours to rest your eyes until the effects wear off.
