What is the threshold for "farsightedness reserve" on the vision screening report that triggers an alarm?

"Doctor, my child's farsightedness reserve is only 50 degrees, is he going to be nearsighted soon?"

"The school physical examination says that the child's farsightedness reserves are insufficient, what should I do?"

……

Every physical examination season, such anxiety fills the parent group. The value of "farsightedness reserve" on a vision screening report has touched the hearts of countless parents. Today, we demystify it and tell you: what exactly does farsightedness reserve mean? How low does the value have to be alarmed?

Look far at the reserve

How much is it safe to save in a child's "vision bank"?

The farsightedness reserve is a child's innate "vision deposit".

With age, the eye axis gradually elongates, and the farsightedness reserve is gradually depleted, and finally tends to be orthopedic (neither nearsighted nor farsighted). It's like a "deposit": the more you save, the lower the risk of myopia; If it is consumed too quickly, it may be overdrawn in advance and become myopia.

Reference value of farsightedness reserves for each age group (focus!) According to the "Expert Consensus on Ocular Hyperopia Reserve in Chinese School-age Children (2022)", the reference range of farsightedness reserve for different ages is as follows:

⚠️ Note: If the farsightedness reserve of a 6-year-old child is less than +1.00D, the risk of myopia will increase significantly in the next 3 years!

Sound the alarm

These signals indicate that the child is "insufficient in savings"

1. The screening report value is lower than the reference value of the same age: if the farsightedness reserve of a 5-year-old child is only +0.75D (normal should be +1.50~+2.00D)

2. Abnormal daily behavior: frequent squinting, rubbing, and looking closely

3. Axial growth is too fast: The consumption of farsightedness reserves is closely related to the development of the axial axis, and if the annual growth of the axial axis exceeds 0.2mm, you need to be vigilant

Case: Xiao Ming is 8 years old, the screening shows that the farsightedness reserve is only +0.50D (normal should be +1.00D), the doctor recommends a review every 3 months and strengthen outdoor activities.

Find out the truth

The three main culprits of farsightedness reserves "shrinking"

1. Excessive eye use at close range:

· Addicted to mobile phones and tablets, he used his eyes for more than 30 minutes without rest

· Improper reading and writing posture (lying on the table, tilting the head)

2. Severe lack of outdoor activities:

· < 2 hours of outdoor activity every day, the eyes lack natural light stimulation

3. Genetic and Environmental Overlay:

· Children whose parents are myopic may deplete their reserves faster

Scientific "saving money"

Slow down consumption and keep the line of vision defense

Optometrists and pediatric ophthalmologists of Dongguan Aier Eye Hospital come to help, how to scientifically delay the rapid consumption of "farsightedness reserves":

1. Outdoor activities: the most effective "value-added artifact"

· Start 2 hours a day: Sunlight stimulates the retina to secrete dopamine and inhibit the rapid growth of the eye axis

· Fragmented time utilization: Walking to and from school, looking into the distance between classes, and climbing mountains on weekends are all good opportunities

2. Eye habits: details make the difference between success and failure

· The 20-20-20 rule: Every 20 minutes of eye use, look at objects 6 meters away for 20 seconds

· Reading and writing posture "three ones": the chest is one punch away from the table, the eyes are one foot away from the book, and the hand is one inch away from the tip of the pen

3. Regular inspection: dynamic monitoring and timely intervention

· Establish a vision file from the age of 3: check the farsightedness reserve, axis, and corneal curvature every six months

· Dilated refraction is more accurate: avoid false myopia interfering with judgment

4. Diet and sleep: the invisible "eye guard"

· Eat more dark fruits and vegetables: carrots and blueberries are rich in lutein and vitamin A

· Primary school students sleep for 10 hours: Lack of sleep will accelerate eye fatigue

A reminder

Misunderstandings and truths that parents must know

1. Myth: "The more farsightedness reserves, the better!" "Truth: Too much hyperopia (such as 5 years old >+3.00D) may cause amblyopia and strabismus, which need to be evaluated by a doctor.

2. Myth: "If the farsightedness reserve is gone, it must be nearsighted!" "Truth: The rate of consumption is related to interventions, and scientific prevention and control can still delay myopia.

Myopia prevention and control small class

To prevent myopia, start by understanding the "farsightedness reserve"!

Children's visual health is a "protracted battle", and farsightedness reserve is the first line of defense. As parents, regular screening, scientific intervention, and leading by example can keep a bright future for their children.

Forward it to the parents around you, so that more families can stay away from myopia anxiety!
