Myth #1: You don’t need a dilated pupil for your first optometry, it’s not good for your eyes. The essence of dilated optometry is to relax the fatigue caused by long periods of excessive tension in the eye muscles, so as to obtain the true refractive state of the eye. If the pupil is not dilated for the first time, the adjustment of the ciliary muscle can make the lens more convex and the refractive power enhanced, which cannot remove the adjustment myopia, the so-called pseudomyopia component, and affect the accuracy of the results, and the dilated pupil has no effect on the eyes. Myth 2: You can’t take off your glasses if you wear them. First of all, it should be clear that there is a difference between true myopia and pseudomyopia, and true myopia is difficult to recover. Pseudomyopia is possible to recover, but the degree of recovery depends on the proportion of pseudomyopia in myopia, for example, there are 100 degrees of myopia, of which only 50 degrees may be pseudophakic, wearing glasses is also difficult to recover. Only 100% of pseudomyopia is likely to be recovered. Myth 3: Watching TV will increase myopia. This depends on the time and distance of watching TV. Myth #4: Low prescriptions require glasses. People with low prescription do not necessarily need glasses for close eye use if they are not professional drivers or have jobs that particularly require clear vision. Please consult your doctor for details, as everyone’s situation is different. Myth #5: If you wear glasses, everything is fine. Myopia is not a problem if you wear glasses. The prevention of myopia can be summarized in the following words: “pay attention to the distance of near eye use” and “reduce the time of continuous near eye use”. The “close eye distance” means that the distance between the eyes and books and desktops should not be less than 33 cm. “Reduce the time of continuous close eye use” means that the duration of reading should not exceed one hour, and that you need to take off your glasses and look into the distance during intervals to avoid excessive eye use, which may increase the degree of myopia. In addition, parents should take a closer look at their child’s desk and chair match during the parent-teacher conference. Myth #6: The number of glasses is unchanging. A pair of glasses with the right fit can be measured by several criteria: the error of the luminosity should not be greater than 25 degrees, the pupil distance error can not be greater than 3 mm, the error of the pupil height can not be greater than 2 mm, if wear a tired, dizzy feeling and does not disappear for a long time, this pair of glasses is not suitable for you. Tips: good glasses are not the same as being able to work once and for all, glasses also need frequent maintenance, usually do not use clothes or napkins to wipe the lenses, take off and wear glasses with both hands, one-handed uneven force, the frame is easy to deformation, there are problems should go to the regular prescription place to debug, while wearing glasses is best every 3 months or half a year to check to see if the degree of change.
