Methods and prevention of unilateral vision correction

With the improvement of living standards, the speed of electronic product updates is also rapid. At the same time, in addition to the rapid pace of electronic product updates, the eyesight of many people is also deteriorating rapidly. At the same time, apart from adults, the age group of myopia is getting lower and lower. Now we can see children as young as four or five years old wearing glasses prematurely. However, wearing glasses for a long time will affect the eyes and face shape, and vision correction is now also a hot industry! Now I will introduce to you the methods and prevention of unilateral vision correction.

Different treatments can be given according to different circumstances.

1. One eye is emmetropia or hyperopia, and the other eye is low myopia (≤3.0D);

(1) Those with normal near vision and correctable far vision can wear monocular corrective lenses, while adults do not need to wear glasses.

(2) For those who need to wear glasses, the lenses should be of the lowest degree that can achieve the best corrected visual acuity (all should be <3.OD), and the lenses should be plano.

(3) Wearing contact lenses in one eye.

(4) If necessary, corneal reshaping surgery such as RK and PRK can be tried (surgery is not suitable for people over 40 years old).

(5) Those who suffer from eye fatigue or abnormal eye position can wear glasses regularly, perform eye muscle training, take appropriate medications, and undergo surgery if necessary.

2. One eye is emmetropia or hyperopia, and the other eye is moderate or severe myopia, which is usually secondary (such as in patients with corneal scars) and is often accompanied by amblyopia:

(1) If your distance vision can be corrected, you can wear glasses with a difference of no more than 3.OD between your two eyes. If it is acceptable (including children or near-term use), it can be appropriately increased, but it should be fully tried before prescription.

(2) Wearing contact lenses in one eye.

(3) Patients with good near vision, correctable far vision, or basically normal retinal vision (laser interference vision) can generally undergo cataract surgery or lens surgery.

(4) Prevent and treat amblyopia, eye fatigue and other complications. Strabismus can be corrected surgically.

3. If monocular myopia is not axial but caused by corneal or lens abnormalities, contact lenses can be used.

Five key points to prevent myopia

Myopia prevention is a long-term project. By establishing children's refractive development files, taking visual environment intervention measures for myopia, and using medical intervention measures for myopia such as drugs, optics, and nutrition, we can build a myopia prevention and control system and achieve the goal of preventing and controlling myopia. To this end, prevention of myopia should start from the following five aspects.

1. Reduce the time of close work, such as telling children to play less computer games, and to let their eyes rest for ten minutes after reading or doing homework for 45 minutes.

2. The posture for reading and doing homework should be correct. Don't read while lying down or on the bed, and don't read in a dim environment. The height of desks and chairs should meet ergonomic requirements.

3. When you have blurred vision, you should go to the hospital in time for treatment. Timely detection is the prerequisite for treating and controlling myopia. Children should go to the hospital for a checkup every three to six months to see if their myopia has worsened.

4. If a child suffers from myopia and has blurred vision (such as difficulty seeing the words on the blackboard or slides), it is recommended to give him correction (wearing frame glasses, RGP, or orthokeratology lenses) and provide drug support treatment.

5. Pay attention to nutrition, eat more fresh vegetables and fruits, and eat less sugar and carbohydrate foods.

The above introduces the methods and prevention of unilateral vision correction. After understanding this, parents with children at home must pay attention to protecting their children’s eyesight. In addition to maintaining the correct posture for reading and doing homework, you must also strengthen the control of the time spent on viewing electronic products. At the same time, eat more vegetables and fruits and less junk food.
