Patient's question:
Problem Description: Doctor, hello. The test results for my eyes at Xiamen Eye Center are as follows: Left eye: 700 degrees myopia, 50 degrees astigmatism Right eye: 700 degrees myopia, 150 degrees astigmatism In the hospital examination, in addition to the myopia and astigmatism mentioned above, no other problems were detected. However, when adding 50 degrees of astigmatism to my left eye, single vision in my left eye still causes double vision. When adding 150 degrees of astigmatism to my right eye, there is no double vision. Specifically, when looking at lights, there is a layer of blur above the lights. Even when looking very close to the computer, my left eye still has double vision. When taking off the glasses, when looking at close objects with lights, such as: left eye nakedDoctor's answer:
Hello! When prescribing for high myopia, optometrists always consider the issue of accommodation-induced fatigue when the patient views near objects. This is also a principle of refraction, which involves appropriately reducing the prescription, usually by about 0.8 diopters. If the prescription is increased slightly, it will inevitably increase the burden on the eyes' accommodation and may lead to blurred near vision.Note: During refraction, while ensuring clear distant vision, it is also important to consider near vision issues. This ensures that the glasses will be comfortable to wear.
