Glaucoma Test

• The basic glaucoma test involves using a machine to blow a puff of air onto your eyes. It is painless; you just have to keep your eyes open for a few seconds.
  
  

Letters on the Wall

• The doctor projects different-sized letters onto the wall and asks you to read them with each eye individually. Your vision level is determined by how well you identify the letters as they get smaller.
  
  

External Exam

• The doctor will shine a light on your eyes to determine their health. He may also use an orange dye on your eyes to check for any scratches or marks. The dye wears off on its own and is painless.
  
  

Lens Checks

Eye Muscle Test
