Dilation of the Eye
How Long Does Eye Dilation Last?
Eye dilation 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 are 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.
