The eyes, like our bodies and thoughts, have a gradual maturation process.

The first critical period: the newborn

Attention: Congenital ptosis, congenital cataracts, congenital glaucoma The neonatal period is a sensitive period of vision development, especially beware of congenital eye diseases.

A month after birth, a fundus examination was performed to determine that there were no congenital problems in the vitreous body and retina. Children with a family history of eye disease, low-weight infants, and premature infants should pay more attention to eye examination.

If the upper eyelid is found to cover the pupil more than 1/2, crystalline turbidity, are abnormal signals, to be vigilant.

The second critical period: 2~3 years old

Concern: farsightedness, astigmatism, anisometropia, strabismus, amblyopia From two to three years old to six years old, farsightedness, astigmatism, anisometropia, strabismus, amblyopia are not easy to detect. But wait until after the age of 6 symptoms to treat, the efficacy is poor. It is recommended to do a myodatic optometry when you are 2 to 3 years old, which can accurately screen for the existence of these hidden diseases. If so, timely treatment through optical and other corrective means.

The third critical period: preschool

Concern: Eye hyperrefractive development Insist on regular vision and optometry. A five or six year old child is found to have no farsightedness and can see things clearly. Do you think his eyes are very healthy? Mistake. "His eyes are actually overdeveloped." Ni Hailong, director of the optometry Department, explained that in general, children aged 3 and below have about 300 degrees of hyperopia, children aged five or six have about 200 degrees of hyperopia, and 10-year-old children may have about 100 degrees of hyperopia.

The fourth critical period: before the age of 12

Attention: false myopia, vision correction Ni Hailong often encountered a situation: some children's vision was originally good, but after the holiday, the vision suddenly decreased, parents quickly took their children to the optician to match glasses.

This is a little hasty. Chances are, these kids are just pseudo-nearsighted. Want to determine whether it is false myopia or true myopia, conventional optometry is not very useful, to go to the eye to do mydriatic optometry.

In addition, the first time before the age of 12 with myopic glasses, also remember to do mydriatic optometry. The degree of mydriatic optometry combined with standard main sense optometry is often lower than the degree of myopia measured by computer or conventional insert optometry, that is, the optometry is more accurate and more comfortable to wear.

This is also a good time to correct your vision. Children over 8 years of age can try orthokeratology after myopia. It is worn at night, not suitable for everyone, the need for a comprehensive assessment of the degree of myopia, corneal shape, eyelid size and the character of parents and children compliance, but also need to review frequently, a year and a half or so to re-customize the replacement, children and parents are a test of patience and determination. But it helps to delay the progression of myopia in teenagers.

The fifth key period: middle and high school students

Attention: High myopia academic pressure, but the eyes can not be too "spell". Professor Yang Yabo, director of the refractive Surgery Center, pointed out that myopia is not well controlled, if the development of high myopia, retinal choroid disease, retinal hiatus or detachment, macular degeneration bleeding, cataracts, glaucoma and other complications may come to the door.

Although myopia below 1000 degrees, astigmatism below 600 degrees, laser myopia surgery can achieve a good therapeutic effect, but the fundus lesions of high myopia can not be changed.

Therefore, we must have this awareness: maintain good eye habits. There is no myopia, very lucky, pay attention to prevention; Already myopic, tighten the string, control the degree.

The sixth key period: after college

Attention: myopia laser surgery wait until college or graduation work, vision has been relatively stable, want to pick the mirror can consider laser surgery. Laser myopia surgery is very safe, but the preoperative need for strict screening, not everyone can do. The requirements of the surgeon are: 18 years of age or older, the degree of myopia does not exceed 1200 degrees, and the contraindication of surgery is excluded.

The seventh critical period: after the age of 40

Attention: macular degeneration, glaucoma, presbyopia If the eye is described as a camera, then from the age of 40, we should pay attention to the problem of negatives. In addition to presbyopia, diabetic retinopathy, macular degeneration, glaucoma and even blindness can come knocking.

It is recommended to do a fundus examination every six months or a year; Control blood sugar, blood pressure and lipids to reduce eye complications.

If you find presbyopia, wear appropriate reading glasses in time. If you do not wear glasses for a long time, it will lead to serious fatigue and may induce other eye lesions.

The eighth critical period: after the age of 60

Attention: Cataracts To deal with cataracts, do not rely on eye drops, the best way is surgery. Be careful not to wait for the crystals to mature before performing surgery, as this will increase the risk of complications. Surgery can also solve cataract, myopia and presbyopia problems at once.
