What chart is used to evaluate near vision? | Jaeger chart or Rosenbaum Pocket Vision Screener |
This is when the lens develops opacities due the age related changes | Cataract |

This is the extraocular muscle function test that assesses the alignment of the eyes | Corneal light reflex test |
This is nearsightedness | Myopia |
This is the term for normal vision | Emmetropia |
This is the term for farsightedness | Hyperopia |
This is refractive error is associated with aging and having a difficulty with near vision | Presbyopia |
