The symptoms of strabismus are somehow straight to the point and you can easily tell if someone has it by just checking their eyes. The condition is also called wall eye, cock eye, boss eye, crossed eye, lazy eye, and squint. It is characterized by eyes that are not properly aligned with each other, due to the lack of the coordination of the extraocular muscles that control the movement of the eye. Here are the symptoms of strabismus that can help you tell if the person is affected by the condition.
One of the symptoms of strabismus is that the eyes are not able to look in the same direction concurrently. The reason for this is that the extraocular muscles may be weak and therefore are unable to coordinate the movement of the eyes. This results in the prevention of binocular vision which is very important as it gives the person a wider field of view, and it is used in depth perception.
Another symptoms of strabismus is that the eyes are incapable of moving together. The direction of the eyes is based on the type of strabismus that the person has. Estropia which is popularly known as crossed eyes is the most ordinary kind wherein one eye turns inward. Another form is exotropia or walleye wherein one eye turns outward towards the temple. There is also the not so common forms hypotropia wherein the eye turns downwards, or hyperopia or vertical deviation wherein the eye turns upward towards the eyebrow.
As a result of the impaired vision from the lack of binocular vision, the other symptoms of strabismus are tilting of the head to look in an object, closing one eye in the bright daylight, and bumping into things.
People who have strabismus cannot use both their eyes simultaneously and therefore they have to close or squint their eyes. They also are unable to correctly judge the depth of an object visually and so they have to tilt their heads. And they also have difficulties calculating the distance of an object therefore they keep bumping into objects.
Additionally, the other symptoms of strabismus include double vision, tired eyes, and blurred vision.
