近视眼会不会患老花眼
老花眼，提起这个词大家一定不会陌生吧？经常会听到有些人会这样说，如果在年轻的时候眼睛近视了，老了就不怕花眼，那么是真的吗，这句话有一定的科学依据吗，下面小编就来大家了解一下吧。
为看清近距离的目标，通过眼部状肌眼的轮廓，眼内状体弯曲度增加，使视野清晰的物体在上面形成清晰的图像，这种为看清近物而改变的屈光力的功能眼的调节力。实际上人眼在45点就退，因为晶状体强健以及病灶状肌功能的减而减弱，因此，人眼能看到近物就会出现力，需要将物体离得稍远些，这早期的老花现象就清楚了。到48小时，调节力进一步下降，视近处的物体描绘不清晰，就需要提示戴老花镜来进行矫正了。
Because people with myopia do not need to wear reading glasses to see near objects, many people mistakenly believe that people with myopia will no longer have dizziness. In fact, this is a misunderstanding. Presbyopia is a normal physiological phenomenon, and people with myopia are no exception, but when looking at close objects, the luminosity of myopia and the luminosity of presbyopia cancel each other out, so sometimes you can see clearly without wearing glasses. Presbyopia will not be reversed. Some old people find that they can read books and newspapers without wearing reading glasses, thinking that presbyopia is good, but in fact, presbyopia will not be reversed. "When presbyopia is getting better, it is best to go to the ophthalmology department to check whether there is a cataract. Cataract is the opacity of the lens, which causes refractive changes after absorbing water. Similar to myopia, this change just'matches' the degree of presbyopia and becomes You don’t need to wear reading glasses to see near objects. This kind of performance is actually one of the early symptoms of cataract."
关于老花眼的小常识
1、还有人说度数不能配得太深，否则会越戴越深。这种说法也不正确。如果老花眼度数不够，视物看不清楚，会眯着眼睛看事物，眼睛易疲劳，这样反而会让眼睛度数容易加深。经验光，精准度数佩戴为宜。
2、很多人都会认为眼睛近视不会出现老花，这样的说法并不正确。老花是一种生理现象，每个人都会出现。到达一定年龄后，眼睛睫状肌功能下降，造成视距离视物困难。有些人出现老花后，近视与老花度数相抵消，所以就产生了近视眼不会出现老花的假象。
3、新配的老花镜为什么不舒服？这个原因有很多。 。
4. Why do I sometimes feel small black spots in front of my eyes or flying around like mosquitoes? If this happens frequently, it may be floaters. This is caused by turbid vitreous or intraocular diseases and bleeding. Black spots, central vision, and tubular vision appear on the eyes, which cannot be cured. You should pay attention to UV protection. Once it appears, it needs to be diagnosed and treated by an ophthalmologist in time, and medications are used to control the deterioration of the condition.
5、我有白内障，还能佩戴老花镜吗？这首先要知道白内障分早、中、成熟期三个阶段。如果是早、中期佩戴变色多焦老花镜可延缓白内障，如果白内障已经发展到了成熟期就要到医院及时诊治，术后三个月方可再配镜，配镜还须佩戴防紫外线功能的变色老花镜，因为白内障手术会植入假晶体，阳光更容易透过晶体照射到黄斑，所以佩戴变色老花镜非常重要。
