Your healthcare provider will ask for a family and medical history and will do a physical examination. The exam will cover how your eyes move and focus. Testing may include:
- Visual acuity (reading letters off an eye chart, or examining young children’s visual behavior).
- Refraction (checking your eyes with a series of corrective lenses to measure how they focus light). Children don’t have to be able to give verbal feedback for these tests.
- Tests of alignment and focus.
- Examination after dilation (widening) of your pupils to determine the health of internal eye structures.
