Optometry, a branch of medical science, deals with the eyes. An optometrist or ophthalmologist has the knowledge and skills to conduct eye, and vision-related tests and accordingly recommends corrective measures, like contact lenses or glasses. They are also specialized in treating specific eye conditions and performing vision therapy to improve eyesight and visual health. The first step is to get an eye examination. Here, we will learn about the types of eye tests performed. What is an eye exam? An eye exam consists of several eye tests conducted under differing conditions to check the health of the eyes. It would involve the use of different medical devices to study the eyes in detail, assess vision, and look out for eye diseases. An eye exam is necessary to detect a possible eye issue early. Detecting such issues early on helps the person go in for corrective measures and undertake steps to improve the health of the eyes.   If you are facing vision-related issues, you must immediately seek help from a licensed optometrist. Adults are recommended to take an eye exam at 40 years of age. It is essential for kids younger than three years to consult with the pediatrician regularly to check the eyes for common problems like cross-eyes and lazy eyes.
