Ophthalmoergographic studies were conducted on three cosmonauts before, during, and after space flight to assess visual accommodation. The results revealed various degrees of deterioration in visual accommodation due to peripheral and central fatigue as a result of overload on the visual analyzer. The findings point to the need for improving illumination aboard spacecraft and mitigation of close-up work to the extent possible. Additional measures will have to include prophylactic measures as well as to render the visual system more tolerant of prolonged stress.
