College major: the same as or similar to the above major.

One eye was blind and the other eye was corrected to 4.8, and the lens power was over 400 degrees. Not suitable for engineering, agriculture, medicine, law and applied physics, applied chemistry, biotechnology, geography, biology, environmental ecological engineering, marine science, marine technology, biotechnology, psychology and other technical majors. Public security organs colleges and universities recruit physical fitness: binocular and monocular naked eye vision, science majors should be above 4.9(0.8), and liberal arts majors should be above 4.8(0.6). There is no red and green color blindness and color weakness. Military Academy: The farsightedness of each eye is less than 4.9 (0.8), and students majoring in guidance, submarine, river diving, heavy tanks, surveying and mapping engineering and radar detection technology failed.

The farsightedness of each naked eye is above 4.8 (0.6); Or the hyperopia of one eye is above 4.7 (0.5) and that of the other eye is above 4.9 (0.8); Or the farsightedness of each eye is above 4.6 (0.4), and the vision correction of each eye is above 4.9(0.8), and the professional students meet the standard. Astigmatism (myopia or hyperopia, the same below) is corrected to more than 400 degrees with 4.8 lenses at a glance, which is not suitable for learning marine technology, marine science, measurement and control technology and equipment, nuclear science and technology, biomedical engineering projects, clothing design and engineering projects, aircraft manufacturing engineering projects and aircraft manufacturing engineering projects. College major: the same as or similar to the above major.
