Ophthalmologists usually suggest that people need to have an eye test every two years. Eye tests don’t just assess your vision but also detects other critical issues such as diabetes and High Blood Pressure. Eye tests check these issues by reading changes in the blood vessels at the back of the eye. People who already have a vision problem are asked to visit the doctor more often. Children need to undergo annual checkups. Since the modern-day kids spend more time on their laptops, smartphones and televisions, they need to check their vision more often.
In general, the recommended frequency in which comprehensive eye examinations need to be done is:
If you are in the age group of 20-40, you need to get your vision checked once in 3 years.
For people falling in the age bracket of 41-64, eye checks are recommended every 2-3 years.
People who are aged more than 65 need to get their eyes checked every single year. Their visual acuity needs to checked more often just because other health factors can deteriorate their vision in a significant manner. People with medical cases such as diabetes, earlier eye trauma or surgery need to check their vision more often.
At a complete eye test, otherwise known as dilated eye exam, the eye doctor uses an eye drops to widen the pupil to have a closer look at the inside of the eye. We are then asked to read an eye chart with and without using various lens combinations. If a person is already wearing a corrective lens, the test results will tell whether or not the lens reading needs a change. The most commonly used eye chart is the Snellen chart. It shows 11 rows of capital letters each reducing size every line after line. The chart at times is viewed using a mirror. This is because of lesser clinic space.
