5 Interesting Facts About Eye Dilatation

  • 7 min read

How Long Does Eye Dilation Last?

Eye dilatation typically lasts between 4 to 6 hours, but can last up to 24 hours in some cases. It depends on the individual and the type of dilating drops used.

What Is a Dilated Eye Exam?

A dilated eye exam is a comprehensive examination of the eye in which the pupils are dilated (widened) using special eye drops. Dilating the pupils allows the doctor to get a better view of the internal structures of the eye, including the retina, optic nerve, and blood vessels. The exam is usually performed by an optometrist or ophthalmologist and can help diagnose a variety of eye conditions such as cataracts, glaucoma, macular degeneration, and diabetic retinopathy. The exam may cause temporary blurriness and sensitivity to light.

Why Do You Need a Dilated Eye Exam?

A dilated eye exam is often recommended to check for a variety of eye conditions that can’t be easily detected during a regular eye exam. Dilating the pupils allows the doctor to get a better view of the internal structures of the eye, such as the retina, optic nerve, and blood vessels. This can help detect conditions such as:

  • Glaucoma: a group of diseases that can damage the optic nerve, which can lead to vision loss or blindness if not treated.
  • Macular degeneration: a condition that causes damage to the macula, which is the part of the retina responsible for central vision.
  • Diabetic retinopathy: a complication of diabetes that can damage the blood vessels in the retina, leading to vision loss or blindness.
  • Cataracts: a clouding of the eye’s natural lens, which can cause blurry vision.
  • Retinal detachment: a serious condition in which the retina becomes separated from the back of the eye, which can lead to vision loss if not treated promptly.

A dilated eye exam is also used to monitor the progression of these conditions and to evaluate the effectiveness of treatment. It is often recommended in adults over the age of 60, people with diabetes, people with a family history of certain eye conditions or people who have symptoms of eye problems such as floaters or flashes of light.

How to Make Eye Dilation Go Away Faster

There is no known way to make the dilation effect go away faster. The duration of the dilation effect depends on the individual and the type of dilating drops used. However, there are a few things that can be done to make you more comfortable while your eyes are dilated:

  • Wear sunglasses: The dilation effect makes your eyes more sensitive to light, so it’s important to protect your eyes from bright light while they’re dilated. Wearing sunglasses can help reduce the glare and make you more comfortable.
  • Use artificial tears: The drops can cause dryness and discomfort in the eyes, so it’s important to keep your eyes lubricated. You can use over-the-counter artificial tears to help keep your eyes comfortable.
  • Avoid alcohol: Alcohol can cause the blood vessels in your eyes to dilate, which can prolong the dilation effect.
  • Be aware of your surroundings: Dilation can affect your ability to focus, so be aware of the environment, and avoid activities that require fine visual acuity such as driving, operating machinery, and climbing ladders.

Please note, If you have any concerns or questions about the duration of dilation effect, please consult with your eye doctor.

What Not to Do After Eye Dilation

Here are a few things to avoid doing after your eyes have been dilated:

  • Do not drive or operate heavy machinery: The dilation effect can affect your ability to focus and react quickly, so it’s important to avoid activities that require fine visual acuity and quick reactions, such as driving or operating heavy machinery. It’s best to have someone else drive you home or arrange for transportation.
  • Do not make important decisions or sign legal documents: The dilation effect can also affect your ability to read and understand written materials, so it’s best to avoid making important decisions or signing legal documents while your eyes are dilated.
  • Do not engage in activities that put your eyes at risk: Dilation can make your eyes more vulnerable to injury, so it’s best to avoid activities that put your eyes at risk, such as contact sports or activities that involve flying debris.
  • Do not expose your eyes to bright light: Dilation makes your eyes more sensitive to light, so it’s best to avoid bright lights and to wear sunglasses if you’re going to be outside.
  • Do not use over-the-counter eye drops: Dilation is done by using eye drops and it’s best to avoid using over-the-counter eye drops for a few hours after the exam, unless recommended by your eye doctor.

When Should You Start Getting Your Eyes Dilated?

The frequency and timing of dilated eye exams can vary depending on an individual’s age, overall health, and risk factors for eye disease. Here are some general guidelines for when to start getting your eyes dilated:

  • Adults between the ages of 20 and 39: A comprehensive eye exam is usually recommended every 10 years or as needed if you have symptoms or a history of eye problems.
  • Adults between the ages of 40 and 64: A comprehensive eye exam is usually recommended every 2 to 4 years or as needed if you have symptoms or a history of eye problems.
  • Adults over the age of 65: A comprehensive eye exam is usually recommended every 1 to 2 years or as needed if you have symptoms or a history of eye problems.
  • People with diabetes: An dilated eye exam is usually recommended every year, or as often as recommended by an eye doctor.
  • People with high blood pressure or high cholesterol: An dilated eye exam is usually recommended every 2 years, or as often as recommended by an eye doctor.
  • People who have a family history of eye disease: An dilated eye exam is usually recommended every 2 years, or as often as recommended by an eye doctor.

It’s important to keep in mind that these are general guidelines, and your eye doctor may recommend more or less frequent dilated eye exams depending on your individual health and risk factors. It is best to consult with your eye doctor to determine the best schedule for your needs.
