Physiological Hyperopia of Young Children at Various Ages

一、 What are the classifications of hyperopia?

1. According to clinical pathology:

Physiological hyperopia: It is an accompanying symptom of eyeball development, which is closely related to age and growth. There is a certain degree of physical hyperopia during growth and development, which is a normal process of eye development.

Pathological hyperopia: The degree is higher than +6.00. The development of eyeball is delayed or stopped which may be caused by genetic and external environmental influences.

2. According to the degree:

Low degree hyperopia: <+3.00. When people are young, eyeballs can use adjustment to compensate, vision of most people won’t be affected before the age of 40;

Moderate hyperopia: +3.00+6.00, Vision is affected, accompanied by discomfort or asthenopia symptoms, excessive use of adjustment will also cause esotropia;

High hyperopia:> +6.00, Vision is affected, it’s very blurred when seeing objects, but visual fatigue or discomfort is not obvious, because the hyperopia is too high, the patient cannot use adjustment to compensate.

二、Groups with frequent hyperopia: young children

Hyperopia changes with age, the following are normal vision (as age increases, the axis of the eye is elongated, vision improves, and the degree of hyperopia decreases until normal)

1) Children between 2 and 3 years old: vision is 0.5 or above, hyperopia is 100 degrees -250 degrees

2) Children between 3 and 4 years old: visual is 0.7 or above, hyperopia is 100 degrees-25 degrees.

Preschool children are still hyperopia. If eyesight is lower than this standard, parents should take the child to the ophthalmology department to check. Therefore, the doctor recommends to go to a professional hospital at least once before the age of 3, to find the problem in time and correct it in time.

3) Children between 4 and 5 years old: vision is 0.8 or above, hyperopia is 75 degrees-200 degrees

4) Children between 5 to 6 years old: vision is 1.0 or above, hyperopia is 75 degrees-175 degrees

5) Children over 6 years old, vision is 1.0 or above, hyperopia is 50 degrees-150 degrees

The normal vision of children at this stage should reach about 1.0. If not reaching, parents should take kids to check in time. If kids’ vision is still below 0.8 after wearing corrective glasses, they may already have amblyopia.
