Eye exams are essential for maintaining good vision and overall eye health. But how long does an eye test take? Factors such as age, family history, medical history, and any new symptoms can affect the length of the visit. Most eye exams last between one and one and a half hours. During this time, the optometrist will evaluate your eyes and determine if prescription glasses would be beneficial.
It is recommended that children have their eyesight checked before entering kindergarten, and their doctor can advise on how often eye exams should be done after that. The symptoms you experience can provide key information about the health of your eyes, which can be useful during eye exam tests. If the eye exam shows any abnormal results, your doctor will discuss next steps to perform further tests or treat an underlying condition. For this reason, routine eye exams that include tonometry are essential to rule out early signs of glaucoma and protect your eyesight. Pupil dilation is very important for people with risk factors for eye diseases, since it allows a more comprehensive evaluation of the health inside the eyes. You may need additional tests if your eye exam results are inconclusive or if they show any point of interest.
It is important to have your eyes checked by an eye doctor every year to take care of your visual needs. Your eye doctor will likely use several instruments, illuminate your eyes with bright lights, and ask you to look through a variety of lenses.

Among the first tests performed in a comprehensive eye exam are visual acuity tests that measure the sharpness of vision. There are several factors that can determine how often an eye exam is needed, such as age, health status, and risk of developing eye problems. During a concealment test, the doctor will ask you to focus on a small object on the other side of the room and then cover each of your eyes alternately while you look at the target.
To get a better view of the internal structures of the eye, the doctor places dilating drops to enlarge the pupils. At the end of the exam, you and your doctor will discuss the results of all tests, including evaluating your vision, risk of eye diseases, and preventive measures you can take to protect your vision. The doctor will ask you to keep your head still and will ask you to follow the slow movement of a portable light or other target with just your eyes. A slit lamp is a binocular microscope (or biomicroscope) that the doctor uses to examine eye structures at high magnification.
