Chromic myopia is a medical condition characterized by the inability to clearly see distant objects due to an abnormal elongation of the eyeball, resulting in a refractive error. Specifically, it is a type of myopia, also known as nearsightedness, that is caused by chromic or gradual changes occurring in the shape of the eye.
In individuals with chromic myopia, the eyeball tends to be longer or have a steeper cornea than usual, which causes light to focus in front of the retina rather than directly on it. As a result, distant objects appear blurry or out of focus, while close objects are seen more clearly. This refractive error can be attributed to genetic factors, environmental factors, or a combination of the two.
Chromic myopia usually develops gradually over time, typically during childhood or adolescence, and may continue to progress until early adulthood. The symptoms often include squinting, eye strain, headaches, and difficulty in reading or seeing signs from a distance. If left uncorrected, chromic myopia can have a significant impact on a person's quality of life, affecting their ability to perform daily activities such as driving, sports, or recognizing faces from afar.
Treatment for chromic myopia may involve prescription eyeglasses or contact lenses to modify the way light enters the eye and correct the refractive error. In some cases, refractive surgery, such as LASIK or implantable contact lenses, may be considered to permanently reshape the cornea and improve vision. Regular eye examinations and follow-up care are essential to monitor and manage chromic myopia effectively.
