This site is being rebuilt. In the meantime, here is what a comprehensive eye exam actually involves and how often most people should book one.
Measuring how clearly you see at distance and up close, and determining the lens prescription that corrects it. This is the part most people picture when they think of an eye exam.
Examining the front and the back of the eye, including the retina and the optic nerve. Many conditions show up here long before they affect vision.
Checking intraocular pressure, one of the indicators used when screening for glaucoma, a condition that develops without symptoms in its early stages.
Assessing how the two eyes work together and how they focus. Problems here often explain headaches or fatigue during reading and screen work.
Frequency depends on age and risk factors rather than on whether your vision feels fine. General guidance looks like this:
Your current glasses or contact lenses, a list of the medications you take, your insurance details, and sunglasses for the trip home if your pupils are dilated during the exam. Dilation blurs near vision for a few hours, so plan not to drive straight afterwards if you can avoid it.
