The Informative Eye to Astigmatism

       Astigmatism, a crucial cause of numerous eye-related problems, typically occurs due to the cornea’s lack of capability to accurately process an image onto the retina. However, some cases of astigmatism have been associated with problems in the lens of the eye. The cornea, which is the outermost, transparent layer that encloses the iris, pupil, and lens, bends light and enables it to focus onto the retina. Photo receptors within the retina sense the light and thus send nerve impulses along the optic nerve to the brain. This organ serves a significant role within the entire phenomenon by being able to form the original image that has been viewed. Yet, improper shaping of the dome-shaped cornea may cause the light that passes through its faulty portion to possess two points of focus, resulting in blurred vision. In a few cases of astigmatism, the cornea may be normal, but the lens of the eye bears slight differences in the shape of its curve. The symptoms of astigmatism consist of blurred vision; possible headaches and eyestrain; and, in children, when one part of a specific pattern or picture can be seen clearer than others. Common causes of regular astigmatism include the distortion that the weight of the upper eyelid resting on the eyeball creates, trauma or scarring to the cornea, the occurrence of tumors in the eyelid, or a developmental aspect. Irregular astigmatism can be as a result of scarring or keratoconus, a condition in which the cornea commences to thin and forms into the shape of a cone. Treatment should take place for astigmatism, which may be composed of the use of cylindrical lenses or toric lenses and laser treatment in severe cases.

       Considering this informative article, my opinion about this ailment holds the identification of being that astigmatism is a dreadful ailment that may result in a severe case if treatment is not undertaken. For instance, my mother possesses this disease, frequently declaring of her inability to view her surroundings properly even with the aid of glasses fitted with cylindrical lenses. Additionally, I believe that this ailment may occur as a result of an immense and varied number of items, resulting at an extremely high risk of vulnerability. To conclude, I view that one is greatly vulnerable to such an ailment and that astigmatism holds the title of being a frightful disease that may be curbed at the precise time if a visit to an optometrist is arranged and treatments take place at the proper time.
