How to use these tools

Each tool has its own page with instructions, the formula it uses and its limits. The eye tests ask you to set your screen size with a bank card first, so that letters and rulers are drawn at their true size.

The results are for information. They do not diagnose a condition. If a result worries you, come to EyeBar Optical or Babar Homeopathic Clinic on Main Road, Kot Bismillah, Kangan Pur.
