A simple test that helps determine whether blurred vision is due to a refractive error or another underlying cause.
The pinhole test is a quick way to check whether reduced vision is caused by a refractive error, such as needing glasses, or by another eye condition.
You look through a small opening (pinhole) that blocks scattered light, and if your vision improves through it, this suggests a refractive error that glasses can likely correct.
At Apollo Clinic Shyamnagar, the pinhole test is often used alongside a visual acuity test to help guide what further testing, if any, is needed.
