The results are recorded separately after ophthalmometry. Resume retesting with dilated pupils. Obviously optometry, first do computerized optometry, then small-pupil photometry, and finally do the main sense of optometry. 3, trial glasses: after the re-test or apparent optometry, are to try on the glasses, the proposed prescription of the glasses on the trial frame by the subjective determination of the examined such as whether there is dizziness, eye swelling, visual fatigue, distance and near vision is clear, and make adjustments according to the situation. 4.Finish the prescription: according to the above trial results give prescription for glasses.
