Patients wear myopic glasses, look at the near place happens blurred, generally consider is two reasons, including glasses degree is not suitable, presbyopia, etc., as follows: First, glasses degree is not suitable: in young people, especially before 30 years old, consider is myopic glasses degree with too deep, that is, the adjustment ability is relatively strong. If you do not do dilated pupils, just in the optician through the computer detection, measured myopia degree will often be high. If the prescription is done according to the computerized prescription, the prescription is high, and the high prescription is good for distance, no problem, but when you look at the near place, you need to use the regulation of your eyes to adjust the focus behind the retina to the front of the retina, so it is very hard to look at the near place, and there may be a blurred situation when you look at the near place for a long time. Because of the long time to move the adjustment, when the adjustment ability is weakened, it feels to see near things happen blurred, can not see clearly. Second, presbyopia: nearsightedness to see near places blurred may be presbyopia, especially patients over 40 years old have myopia, with the right degree of myopic glasses, when looking at objects near, resulting in a decline in the adjustment function myopia degree is not appropriate, can not compensate for the lost adjustment function, so look at objects near blurred, should adjust the degree to see objects near clearly.
