How to test your eyesight yourself

The method of self-testing vision is relatively simple. We can test the range of our vision ourselves in an eye clinic. As long as we stand in the right position, we can check the range of our vision according to the direction specified by the doctor. If we want to test our eyesight ourselves, we can also use the light response method and eye covering method. There are many ways to check. You can try the following methods based on your own physical examination.

How to test your baby's vision

In daily life, you can use the following methods to detect your baby's vision:

TIP1: Light response method

Two months after birth, the baby's sensitivity to light becomes more acute. When light suddenly shines into the baby's eyes, he or she will unconsciously squint and frown. If parents find that their baby has no reaction to light, it means that the baby has vision impairment and they should see an ophthalmologist in time.

TIP2: Eye Covering

Parents can cover the baby's eyes alternately and observe the baby's reaction. If the baby doesn't care when you cover one eye, but pushes the covering away with his hand because he can't see clearly when you cover the other eye, it means that the eye that was covered first has vision impairment.

TIP3: Watch and follow movement method

Two months after birth, babies have the ability to look at and follow moving objects, and this ability becomes stronger as the months go by. So if parents find that their baby cannot keep a steady gaze on the target, or appears to be looking aimlessly, it means that there is something wrong with his vision!

TIP4: Eye chart test method

This is the most common method of testing vision. Babies under 5 years old may not be able to use this method due to limitations in their cognitive abilities, but if the baby is over 5 years old, parents can guide him or her to use the vision test chart through parent-child games.

Tips: The normal vision range for children of different age groups in my country is: 2 years old: 0.4-0.5; 3 years old: 0.5-0.6; 4 years old: 0.7-0.8; 5 years old: 0.8-1.0; 6 years old: 1.0 or above.

How to read baby's eye chart

Keeping an eye chart at home can quickly and accurately measure your baby's vision. The eye chart mainly checks central vision, that is, checks the concave visual acuity in the center of the baby's retinal macular area. Parents can choose a children's eye chart according to their baby's preferences. Currently, common eye charts on the market include children's graphic eye chart, E-label eye chart, etc. Parents should try to get their baby to cooperate with the eye chart, such as asking the baby to imitate the animal figures in the chart, to check whether his or her vision is normal.

Since a baby's vision will not become completely stable until around the age of 12, parents should always pay attention to changes in their baby's vision. If you find that your baby has abnormal vision, you should consult a doctor immediately.
