It's important for adults 40 and older to have eye exams every 2 to 4 years to check for problems. Those who have a history of eye problems or who are at risk for developing them should see an eye doctor every year. This is particularly important if you have risk factors or a family history of eye problems.

Usually the eye exam will last around 20 minutes.Some are even shorter about 10 or 15 minutes.But some people will spend a longer time on the eye exam, maybe about an hour depending on whether you need to have a comprehensive eye exam.nswers (2).
