Q: How are the take home tests sold? And can they be used repeatedly?
A: Great questions! The Zhang Ring Test™ is sold in a tablet consisting of 50 sheets. Simply tear one page out and send it home with your patient. Explain to them the directions and tell them to immediately call if they see distortion or a break in the ring with their peripheral vision. You should test them before sending them home. The test may be repeated as long as it remains unblemished and in good condition.
