A tool to facilitate common tasks in ophthalmic research: Conversion between different visual acuity notations (Snellen, logMAR and ETDRS), counting of patients, recode right and left eyes and reshape eye side specific variables between wide and long format. The 'eye' package also contains a real life data set of people with intravitreal injections with anti-vascular endothelial growth factor (anti-VEGF), made available by Fasler et al. (2019) <doi:10.1136/bmjopen-2018-027441>. Visual acuity conversion is based on Schulze-Bonsel et al. (2006) <doi:10.1167/iovs.05-0981>, Gregori et al. (2010) <doi:10.1097/iae.0b013e3181d87e04>, Beck et al. (2003) <doi:10.1016/s0002-9394(02)01825-1> and Bach (2007) <http:michaelbach.de/sci/acuity.html>.
