After an eye exam, especially if your eyes were dilated, the time frame before you can safely drive varies. Generally, it's advised to wait several hours. The dilation drops used by your optometrist cause blurred vision and light sensitivity, impacting your ability to drive safely. The exact time can differ based on the individual's response to the dilation drops and the type of drops used. It's best to discuss this with your eye doctor who can provide a more precise time frame based on your specific case.
