| In this study we also look at several other aspects of vision. These include how well patients can see at reading and computer distance, how large their pupils are in bright and dim light, and how well they can distinguish light from dark under different lighting conditions (contrast vision). We assess reading ability by measuring reading speed and clarity. We also look at the remaining prescription of the eye, such as any small amount of far- or nearsightedness or astigmatism. In addition, patients complete short questionnaires about their vision in daily life, including their need for glasses and any light-related symptoms. Finally, we check the eyes for any findings that may influence vision, such as early signs of posterior capsule opacification. | — |
