Eye exams help maintain your overall health and vision. But what happens once the exam is over? Can you simply jump behind the wheel and carry on with your day? Depending on the tests performed, you may need to wait before driving after an eye exam.
Vision is at the core of safe driving, and while an eye exam can help you be safer on the road by providing corrective lenses, it’s important to understand how certain eye tests affect your ability to see clearly.
Factors That May Affect Driving After Your Eye Exam
You’ve just completed your eye exam. What’s next? Depending on the tests conducted during your appointment, you may notice temporary effects on your vision. Here’s what to expect:
Dilated Eye Exams
One of the most common reasons for delayed driving after an eye exam is pupil dilation. When your eye doctor uses dilating drops, your pupils expand to allow a better view of the retina and optic nerve. This procedure is especially common during diabetic eye exams, since diabetes tends to affect the retina first.
While it’s crucial for early detection of conditions like glaucoma or macular degeneration, dilation causes side effects, including blurry vision and light sensitivity that can last several hours
These effects make it difficult to see clearly, particularly in bright sunlight or at night. It’s usually recommended that you arrange alternative transportation if pupil dilation is involved.
Numbing Eye Drops
If you’ve undergone intraocular pressure testing using numbing eye drops, you might experience mild blur or temporary discomfort. While these effects wear off faster than pupil dilation, they can still impact your ability to drive safely.
Tests That Don’t Affect Vision
Some parts of your exam, like visual acuity tests (the classic “read the letters on the chart”) or peripheral vision assessments, typically don’t impair your vision afterward. These tests are focused more on measuring the sharpness of your eyesight rather than altering it, so they’re unlikely to affect your ability to drive.
However, every person reacts differently. When in doubt, always follow your optometrist’s guidance about when it’s safe to drive.
An Inside Look at Eye Exams
Knowing what happens during an eye exam can give you a better idea of why certain tests might make driving temporarily inconvenient.
The exam often begins by discussing your family and medical history. This is especially important if it’s your first exam with a new optometrist. Understanding your background helps us identify any potential concerns tied to genetics or past conditions. From there, preliminary tests typically involve:
- Visual acuity: Measuring how well you see at various distances using a Snellen chart.
- Eye pressure (tonometry): Testing for signs of elevated pressure inside the eye, which could indicate glaucoma. These tests might include the “puff of air” or using a small plunger device.
Once preliminary testing is complete, your optometrist may conduct additional assessments, including:
- Refraction testing: This helps determine your exact prescription for glasses or contacts by analyzing how well your eyes focus light through various lenses.
- Pupil dilation: This allows your doctor to check internal eye structures for signs of disease or damage.
- Slit-lamp examination: Using a specialized microscope, your optometrist examines the front portion of your eye, including your cornea and lens, to detect irregularities like cataracts.
- Retinal exams: With the help of a bright light, your doctor evaluates the health of the retina and optic nerve at the back of your eye.
Each test serves a unique purpose. While some won’t affect your day-to-day activities, others, like pupil dilation, require temporary adjustments, such as arranging a ride home after the appointment.
Tips for Post-Eye Exam Care
Once your exam is complete, it’s important to prioritize comfort. As we discussed above, many exams don’t leave any lasting effects. We’ll let you know ahead of time so that you can come to your appointment prepared.
Here’s how to care for your eyes after an appointment:
Handle Dilated Pupils with Caution
If your pupils have been dilated, it’s common to feel extremely sensitive to sunlight. Carry a pair of sunglasses with you to reduce glare and discomfort, especially if you expect to spend time outdoors.
Limit Screen Time
Post-exam blurriness can make it harder to focus on screens or small text. Give your eyes a break by avoiding digital devices or reading fine print for a few hours.
