Evaluation of visual functions during space flight - understanding and assessing the changes in the optical function during space travel

Prof. Arieh Solomon, Department of Ophthalmology, Tel Aviv University

Medical reports from previous space flights have presented the results of two examination of the pilots’ visual functions: near and far visual acuity and examination of the retinal function through an AMSLER grid. The various visual functions can be assessed through several additional tests. All together these can provide a complete picture as to whether weightlessness affects the visual system. The tests that are going to be conducted during this mission are: color vision, three-dimensional vision, sensitivity to resolving the target-background difference, field of view, AMSLER grid, near and far visual acuity.
