What causes squinting of eyes?
Squint (also known as strabismus) is a condition that arises because of an incorrect balance of the muscles that move the eye, faulty nerve signals to the eye muscles and focusing faults (usually long sight). Many children with squints have poor vision in the affected eye.
Note that it's normal for a newborn baby's eyes to wander or cross now and then, up to about 4 months of age. He's just getting the hang of making his eyes work together. If your baby's eyes seem crossed most of the time, though, or if it doesn't get better, talk with the doctor.
- By 2 weeks, Baby might start to recognize her caregivers' faces. She will focus on your face for a few seconds as you smile and play with her. Just remember to stay within her field of vision: it's still around 8-12 inches.
- One such misconception is that the eyeballs do not grow or change size from the time you are an infant, up to adulthood. This isn't quite true, although the eyes change size less than any other part of your body as you grow and develop into an adult. As our eyes age, we become more susceptible to eye diseases.
- Your unborn baby's eyelids remain closed until you're about 28 weeks pregnant, which allows the retinas to fully develop. After that time, her eyes open and even begin to blink. Here's a fun fact: As soon as their eyes open in the womb, twin babies can find each other -- and will touch each other's faces or hold hands!
Infantile esotropia is a type of crossed eyes that appears in babies during their first year of life. Crossed eyes can also occur later in life. It's usually caused by physical disorders, like eye injuries, cerebral palsy, or stroke. You may also develop crossed eyes if you have a lazy eye or are farsighted.
- “Low vision” or “visual disability” is more accurate for people who have some degree of sight, but who have for example a limited range of sight and focus that cannot easily be corrected with spectacles, who are squint (their eyes do not focus together), who need special lighting to be able to see, who have blurred

- In the extreme, complete blindness in one eye generally leads to the blind eye reverting to an anatomical position of rest. Although many possible causes of strabismus are known, among them severe and/or traumatic injuries to the afflicted eye, in many cases no specific cause can be identified.
Treatment may include a combination of patching, eye glasses, eye drops, eye exercises, and surgery. Treatment using the spectacles to correct any refractive errors may cure some types of squint, but to be effective the spectacles must be worn most of the time.
- Other conditions associated with strabismus include: Stroke (the leading cause of strabismus in adults). Head injuries, which can damage the area of the brain responsible for control of eye movement, the nerves that control eye movement, and the eye muscles. Neurological (nervous system) problems.
- At birth an infant can detect light and motion, then can make out faces and large shapes. By the end of the first month, a baby can make eye contact and focus on objects about 12 inches away. By the time a baby is 3 to 4 months old, he can distinguish between colors and focus on smaller objects.
- Babies this age can focus on shapes that are close by, but see distant objects as blurry because they are nearsighted. As babies grow, eyesight improves. By the end of 3 months, they can follow a moving object, are more interested in shapes and patterns, and can spot familiar faces, even at a distance.
