To enter oneself for an examination in the flight college, one must first have two physical examinations 2 or 3 months before the college entrance examination. The first is the preliminary examination, which is generally divided into four major subjects: ophthalmology, otolaryngology, surgery and internal medicine. Applicants are generally required to check ophthalmology first, because ophthalmology has the highest elimination rate. Most applicants will be eliminated in this subject, and future subjects will not have to be checked. When I applied for the examination that year, there were 10 boys in the whole school. As a result, 7 boys were brushed off in the first round of ophthalmology. Ophthalmology mainly examines vision and fundus, requiring normal vision and free from myopia, hyperopia, trachoma and other diseases, as well as color blindness, color weakness and other defects. Pilots use a special "C" table to check their eyesight, with 8 directions. It is far more difficult than the "E" table.
