Nowadays, many babies have a strong interest in TV and mobile phones. Parents will not stop their babies and will let them watch or play frequently. But parents have found that their baby's vision is not as good as before. When watching TV, they get closer and want to screen their baby's vision. So, how to check the vision of a 3-year-old baby?
1. Check if the eyeball is symmetrical
Perform an eye contour examination under diffuse light. The examination includes the size of the eyeball and whether the shape is symmetrical. Preschool children generally suffer from esotropia or esotropia, but there are also a few patients with exotropia. Covering the eyes can effectively determine whether it is dominant or recessive.
2. Visual examination
The correct examination and analysis of hyperopia or myopia can make accurate judgments on the reading of farsightedness vision. Teenagers' eyes have strong regulatory abilities, and when they suffer from mild myopia, their vision for both farsightedness and myopia will appear normal.
3. Inspection mirror examination
The most common condition is that the small reddish edges of the nipple appear blurry, and patients with high hyperopia have a yellow transparent mass. The incomplete field of view can form a small crescent shape below the nipple.
Whether a baby is nearsighted or farsighted, it can have an impact on their own health. So parents need to take their babies for timely correction and treatment, otherwise it will affect the eyes. At the same time, they also need to listen to the doctor's advice, receive timely treatment, and not judge their own condition without authorization.
