Photometry is recommended to go to the hospital, because the hospital photometry is more professional and more accurate, and the optical store is not as accurate as the hospital.
Optometry is the process of checking how light rays are gathered in the eye, and it is used to measure the degree of difference in concentration and dispersion between the examined eye and the normal eye, taking the state of the normal eye as the standard. Since many people will almost always be associated with eyeglasses in their lifetime, optometry is one of the most basic, common but important tasks for optometrists, so as far as the term optometry is concerned, it is familiar to both ophthalmologists and the general public in social life.
Optometry:
Optometry has a variety of methods, from whether or not to let the eyeball adjustment of the stationary, can be divided into dilated pupil optometry and small pupil optometry. From the method of optometry, can be divided into other sense of optometry and the main sense of optometry.
Optometry equipment, in addition to optometry lens box and the inspection mirror and other conventional equipment, there are computerized optometry and comprehensive optometry. Computer optometry has been overly publicized, but through a large amount of information analysis, computer optometry, although it is the crystallization of high-tech, but it can only make a preliminary screening of the refractive state, and can never be its results as the standard of optometry.
Comprehensive optometry set a variety of inspection functions in one, since the birth of the early 20th century, continue to improve and develop, it is not only able to check the refraction of the spherical lenses, but also correctly find out the number of astigmatism and astigmatism axial, in addition, but also on the eye position, regulation, as well as binocular monocular function to make the correct judgment, proficiency and the use of comprehensive optometry, is to improve the level of the key measures of optometry.
