Pupillary distance 60 with 62, refers to the pupillary distance of 60 mm in the prescription glasses, with 62 mm, this situation is generally does not matter. The pupillary distance is the distance between the pupils of the two eyes, the correct measurement of the pupillary distance has an important role in the configuration of glasses and wearing comfort, the general configuration of glasses does not have to be tight, there can be a 2 mm error, such as the patient’s pupillary distance of 60 mm, the configuration of glasses for 62 mm, most cases will not affect the fit of glasses and eye vision. Patients are advised to wear them for a short period of time for observation, and in the absence of discomfort symptoms, they can continue to wear them normally, which generally does not affect the eyes too much. However, if patients experience discomfort, such as dry eyes, sore eyes, eye swelling, headaches, dizziness and other symptoms, they should immediately stop wearing them and go to a hospital or regular optical store to re-measure the pupil distance and configure their glasses. Because some people have sensitive eyes or high myopia, glasses pupil distance even if only 2 mm error, but also easy to produce prismatic effect, that is, a beam of light by multiple refraction, can lead to patients appear to distortion, blurred vision, long time wearing such glasses will appear eye pain, dizziness and other feelings, in the long run may also aggravate the degree of refractive error or astigmatism, serious even completely unable to wear normal, to normal life and health. This can have an impact on normal life and health. It is important to note that the refractive error and astigmatism must be measured accurately when dispensing glasses, otherwise it will affect the vision and the wearer will experience significant discomfort. For first time wearers, choose more accurate pupil distance glasses as possible to avoid irritation and discomfort when wearing them for the first time.
