Eye Shape and Different Eye Problems
There is no need of explanation why do we need our eyes. Rather we will take no time jump into the subject today. We will discuss the eye shapes and problems of the eyes for which you need an affordable eye care.
Eye Shape
Light should pass through the eye cornea and crystalline lens when you have healthy eyes. This also focuses on retina and is found behind the eyeball. This process helps the images to pass through the optic nerves followed by the visual cortex located in the brain. The right and healthy eye shape helps in focusing as well as convergence. When eyeballs have an improper shape like hyperopia or shortened or myopia elongated vision could be problematic.
Blurred vision (refractive errors)
When you have myopia or nearsightedness you can see things clearly in close but blurred in distance.
When you have farsightedness or hyperopia you can see things clearly in distance but blurred in close.
After 40 if you have issues to read something in small printing in close, this condition is referred to as presbyopia. This is very common in people; almost one in three suffer from this in the United States.
Ill shaped cornea also causes blurred vision that is known as astigmatism.
Crossed Eyes (strabismus)
Strabismus happens when the eyes are not in the same line or are crossed but one eye remains straight any other time. Different strabismus forms are -
Esotropia – Both or one eye is turned to the nose
Exotropia – Both or one eye is turned out
Hypertropia – Both or one eye is turned up
Hypotropia – Both or one eye is turned down
Lazy Eye (amblyopia)
Amblyopia or lazy eye is a common problem in children.
When the brain and the eyes do not work together conditions like lazy eye occur. The brain keeps on ignoring information from one eye and problems with vision development occurs.
Unhealthy Eye Shapes
The Myopic Eye
When you have myopic eyeball there is more distance than needed between the retina and the lenses. As a result, the image comes into focus and it goes to the retina. It makes the retina that has highly photosensitive cells to catch a blurry image.
The Hyperopic Eye
The hyperopia has the exact opposite condition. Here the eyeball is very short and the distance of light traveling is also very short. When an image is focused behind the retina the distant items come clear and close items become blurry.
The Cornea
The cornea is not flexible, that is static. The crystalline lens is exactly the opposite and flexible. That means it adjusts the shape according to the focus. A healthy cornea has dome-like shape. A weak cornea cannot hold the round shape and comes outward and downward as it bulges. The rightly curved cornea assures that the incoming light bends the right way and falls on the lens and an improperly shaped cornea causes a refractive error. When the cornea is uneven or shape is irregular the retina image becomes distorted.
