The main manifestation of myopia is that it is clear when looking at close distances and clearer when reading small words, but blurred when looking at distant places, so that the cause of myopia is considered first. It depends on the age of the patient. If it is an adult with this condition, a simple computerized optometry can be done at the hospital. If the child is younger than 12 years old, after the computerized optometry, you need to do a dilated optometry with compound tropicamide drops to dilate the pupil to see if the child is truly myopic or pseudomyopia. Patients with myopia should pay less attention to cell phones and computers, reduce the time and frequency of near eye use, and take a break from near eye use for about 30 minutes. Don’t stay up late at night and strengthen outdoor activities. Patients who are older than 18 years old can consider laser surgery for myopia if they need to get rid of their glasses. Some patients will choose liquid keratoplasty, which depends on the patient’s age and with the state and myopia to make the final choice.
