Infants should be able to see as well as adults by age 6 in terms of focusing, color vision and light perception. months old.
To determine if your baby's eyes are developing normally, the doctor will usually do the following tests:
Pupillary response tests check that the eye's pupil opens and closes correctly in the presence or absence of light.
The "Fix and Follow" tool Test determines whether your baby's eyes can see an object, e.g. g. a light, and follow it when it moves. (Infants should be able to fixate on an object shortly after birth and follow an object by 3 months of age.)
Preferential Gaze involves the use of cards written on one side blank and lined are the other. page to draw a child's eye to the stripes. In this way, vision can be assessed without the use of a typical eye chart.
Eye screening for preschoolers
Some parents are surprised to learn that preschoolers do not need to know their letters to take certain eye tests, even if they are too young or shy to verbalize.
Some common eye tests used specifically for young children are:
LEA symbols for infants are similar to regular eye tests that use
-letter charts, except special symbols in these tests include an apple, a house, a square, and a circle.
Retinoscopy is a test in which a light is shined into the eye to look at the reflection from the back of the eye (retina). This test helps determine if your child has a cloudy lens (congenital cataract) or significant ametropia.
The Random Dot Stereopsis test uses special dot patterns and three-dimensional glasses to measure how well your child's eyes work as a team.
In addition to nearsightedness, farsightedness, and astigmatism, common vision problems in school-age children include:
Lazy eye (amblyopia):
Your eye doctor wants to rule out amblyopia, or "lazy eye" "eye ", meaning decreased vision in one or both eyes with no demonstrable anatomical damage. Unfortunately, amblyopia is not always correctable with glasses or contact lenses and may require an eye patch to strengthen the weaker eye.
Misalignment of the eyes (strabismus):
Squinting or misalignment of the eyes (strabismus) can have various causes, such as problems with muscle control in the eye or affected eyes Strabismus is a common cause of amblyopia and should be treated become in d he early childhood for a normal development of sight and vision.
It is the inability to maintain the alignment of the eyes when looking at close objects. Convergence insufficiency can cause eye discomfort and even double vision when reading.

Signs that your child needs glasses
Here are some signs that your child may need glasses:
Squinting. Squinting can be a sign that your child has a refractive error that affects how the eyes focus on an image.
Squinting can temporarily help your child improve focus and clarity on an object.
Tilt your head or cover one eye. Your child can cover one eye or tilt their head to adjust the viewing angle to improve clarity. This could be an indication that the eyes are misaligned or that your child has amblyopia, also known as lazy eye, which is one of the most common eye conditions in children.
Sitting too close or holding the television portable devices too close to the eyes.
Sitting too close to the TV, holding wearable devices too close to your eyes, or bowing your head while reading are all possible signs of poor vision. People with nearsightedness or short-sightedness have clear near vision and poorer distance vision. Zooming in on an object makes the image bigger and clearer.
Excessive eye rubbing. Excessive eye rubbing may indicate that your child is suffering from eye strain or fatigue.
Complaints of headache or eye pain. If your child complains of eye pain or headaches late in the day, they may be straining their eyes too much to focus due to blurry vision.
