Take care of your eyelgasses

First, check your vision in time.

Young people are still in a period of physical development, while the heavy pressure from study also come accompanied by myopia. As a result, young people should be regularly inspected visually. Once vision-loss or poor vision is found and one’s vision is less than 0.8, an ophthalmologist should be called for checking who can find the reasons. Take into consideration that whether it is needed to wear glasses as soon as possible to wear glasses, or a faster decline in visual acuity would be happen.

Second, avoid wearing glasses if you suffer from pseudo-myopia.

The main reason of pseudo-myopia for young people is the heavy pressure of study which forces students to spend too much time in reading and writing with eyes. So vision decline caused in a short time are usually pseudo-myopia. In fact, the axial of people who is pseudo-myopia is the same long as normal people. As long as there is appropriate rest of eyes, solving the ciliary muscle spasm, vision will be back to normal. So people who are pseudo-myopia cannot wear glasses. If wearing glasses, the eyes will gradually change into real short-sighted with the formation of optical lenses.

Third, glasses need optometry

Glasses must be tested well and make sure about the vision strength. The steps are: computer optometry + plug-chip optometry + video optometry + release pupil optometry. Glasses belong to physical therapy ophthalmology equipment. A pair of glasses with accurate diopter can help people who are suffering from myopia or hyperopia or astigmatism or other refractive errors regain a clear, bright world. In contrast, low vision glasses cannot play the role of correction; a pair of glasses with higher vision can cause dizziness, nausea, vomiting, so that eye fatigue and other undesirable consequences will appear.

Fourth, avoid excessive optical.

Young people with myopia should not have a pair of glasses whose vision higher than 1.5 strengths. Some call for short-sighted vision to reach 1.5. As a result, dizziness, eyes bulging, eye fatigue and other phenomena after wearing glasses. Generally, 1.0 or 1.2 strengths are all right, that is, the strength of myopia glasses can reach the best results at the lowest strength. So, be sure to grasp the principle of “rather low than high”.

Fifth, pupil distance should be measured.

The preparation of a pair of qualified glasses need: first of all, in addition to accurate optometry, the assembly must meet technical parameters, such as the optical center based on pupil distance, which is the key factor when assembly qualified glasses; otherwise, it will result in deviation from the optical center, optical centers vertical deviation and many other problems. So it will not eliminate eye fatigue, material deformation will occur when see objects. Clarity weakened, dizziness, vomiting, bulging eyes and other undesirable phenomena appear.
