Parents: Why my child sees blur?

First you should tell how long, which eye, simultaneous symptom such as eye pain, red eye etc. to doctor about your child’s complain. After excluded congenital cataract, glaucoma, fundus abnormalities and nervous disease, the most common reason for it are optometric problems, such as myopia, hyperopia and astigmatism, sometimes keratoconus.

Follow the instructions according to your child’s age:

Myopia

1. 0~2 years old. Recommend using powerful cycloplegica, then exam the refractive status carefully. If there is no existed strabismus or high myopia, it is no necessary to prescribe glass wear, just observe. If high myopia, it is necessary to correct partial myopia.

2. 3~6 years old. Also recommend using powerful cycloplegica to correct partial myopia. As to less than -1.5D, observation is the treatment. The aim of this stage is to cure and prevent amblyopia.

3. 6~18 years old. The principle of wearing glass is MPMVA(maximum plus to maximum visual acuity). You should avoid accommodation of the eyes when in optometry. Avoid overcorrection. Generally, the refractive error would increase -0.5D to -0.75D per year. If exceeds, go to ophthalmologist to exclude eye disease such as glaucoma or wear RGP to prevent the hyper-increase. When the refractive error diopter is less than -3.0D, just wear the glass for distant seeing, if more than, wear all day.

Hyperopia

1. 0~3 years old. Also recommend using powerful cycloplegica to correct partial hyperopia which is more than 5.0D. If less than 5.0D, just observe. If amblyopia and strabismus, fully correct the refractive error.

2. 3~6 years old. If with amblyopia, strabismus and high AC/A, fully correct the refractive error. Mild hyperopia need no treatment.

3. 6~18 years old. Mild hyperopia need no treatment. Prescribe glass to child with visual fatigue and tell this kind of patient for wear for distance. If with amblyopia, strabismus and high AC/A, fully correct the refractive error.

Astigmatism

1. 0~2 years old. If with high astigmatism, amblyopia and strabismus, fully correct the astigmatism. Mild astigmatism need no treatment.

2. 3~6 years old. Fully correct the astigmatism.

3. 6~18 years old. Child always like see in wryneck and squint Fully correct the astigmatism. If have adaption problem, just correct insufficiently, then add gradually to full. As to the irregular astigmatism, RGP is the preference.
