The Tibetan Eye Chart is a popular tool for improving vision naturally by exercising the eye muscles. However, there are several synonymous terms used to refer to this test chart, including the Snellen Eye Chart, the LogMAR chart, the Jaeger chart, and the Rosenbaum chart. While all of these charts have a different layout and use different letter sizes, they are all designed to test visual acuity and help diagnose potential vision problems. Whether you are trying to improve your vision or simply looking to get an eye check-up, it is important to find the right test chart that suits your needs and provides accurate results.
