How to wear glasses for amblyopia? _Industry News_

Amblyopia is a common ophthalmology disease with poor eyesight, and the refractive status of the eyes of many amblyopic patients is also very different, and it is also different in optometry. Some amblyopia patients are also accompanied by other strabismus, so it is necessary to match glasses according to different vision conditions. Let’s take a look at how to match glasses with amblyopia. For amblyopia without strabismus, use better-corrected vision glasses to reduce the diopter of hyperopia to achieve better vision. For hyperopic eyes, you can choose lenses with higher refractive power, and for near-sighted eyes, choose lenses with lower refractive bases. It is based on prescriptions given for refractive status, vision, age, etc., based on the principle of better vision correction. After the vision is corrected, it is no longer amblyopia. If the correction effect is good after the spectacles, you must insist on wearing glasses to consolidate your vision. . Amblyopia with ametropia, if a child with refractive error is found through mydriatic refraction, the ametropia needs to be corrected, and it is necessary to wear glasses. The power of optometry glasses is mainly used to obtain better vision. Children with amblyopia need to be checked regularly. Adjust the lens according to the refractive power of the eye, and it needs to be adjusted once every three months or six months to adapt to the growth and development of the child. Accompanied by esotropia, amblyopia, esotropia, and amblyopia children’s glasses require sufficient spectacles for hyperopia. When fitting glasses, first consider correcting esotropia, and then correcting vision. Mydriatic refraction should be performed every six months or a year after the glasses are fitted. If it is accommodative esotropia with positive eye position and good vision, the lens can be lowered according to the actual situation, generally 1D is reduced in 1 year; partially accommodative esotropia or non-accommodative esotropia, according to optometry, can reduce appropriate hyperopia according to the actual situation degree. Amblyopia accompanied by astigmatism is generally not increased or decreased, and the amount of hyperopic astigmatism and myopic astigmatism can be reduced as appropriate. And it is required to have an optometry once every six months or a year. Adjust the lens according to the actual refractive condition and the changes in the degree of strabismus and corrected vision. Accompanied by exotropia and amblyopia, if it is a preschool-age child, hyperopia is less than or equal to +2.50D, and the impact on vision is not significant, you can temporarily not wear glasses. When it exceeds +2.50D, use the low-correction optics method. Need to obtain a lower power prescription for correcting vision to consolidate better vision. After the glasses are fitted, when the eyes are used at close range, it will increase the adjustment and convergence power, promote the contraction of the medial rectus muscle, and turn the eyeball inward to correct exotropia.
