How do i find out what my refractive error is?

Ophthalmologist

Refractive_error
If you need to find this out to get glasses, you will need a prescription from your ophthalmologist. If you already own a pair of glasses an optical shop can tell you the numbers. The reading takes specialized instrumentation and you cannot find this out from things found in the non-optical environment.
