What Affects the Test
Reasons you may not be able to have the test or why the results may not be helpful include:
- Having a sore on your eye or an eye infection. This increases your risk of an eye injury during the test.
- Being extremely nearsighted, having an irregularly shaped cornea, or having had major eye surgery in the past.
- Blinking or squeezing your eyes shut during the test.
- Having had laser refractive surgery (such as LASIK).
