The most accurate way to determine whether the prescription of glasses has become high is to go to a regular ophthalmology department, conduct a standardized optometry process, and determine whether the prescription of glasses is inappropriate based on the results of the optometry. It is recommended that young people with high astigmatism, high farsightedness or high myopia should undergo dilated optometry in order to more accurately determine the prescription of their eyeglasses. If there is a difference of more than 50 diopters between the current prescription and the original prescription, it is recommended that the eyeglasses be replaced. If the difference is less than 50 degrees, it is recommended to continue to wear the original glasses and review them in about 3 months. You can also determine whether your glasses prescription is getting higher by your daily eye habits. If you need to squint to see things in the distance, or if you can’t see things as clearly as you did when you first got your glasses, it is a good sign that your glasses are not the right prescription, and you need to go to the hospital for a second eye examination.
