An eye exam involves a series of tests to evaluate your vision and healthcare professionals check for eye diseases.
Each test during an eye exam evaluates a different aspect of your vision or eye health. An eye exam helps detect eye problems at their earliest stage — when they’re most treatable. Regular eye exams give your eye care professional a chance to help you correct or adapt to vision changes and provide you with tips on caring for your eyes. Several factors may determine how frequently you need an eye exam, including your age, health and risk of developing eye problems.
