What is MyopiaMyopia, or commonly known as shortsightedness, is defined medically as the elongation of the eyeball. In essence, because the image falls behind the retina instead of on the retina, resulting in blurred imaged to be formed. The result is the sufferer of myopia is unable to see distant object clearly, but able to see near distant object. Types of MyopiaAccomodative Myopia When our eyes engaged in excessive near work, our eyes ciliary bodies are kept constantly engaged in a tense condition. (See How the Eyes Work and also the Accomodation System & Accomodation Process) After subject in this tense condition for extended period of time, when the eyes need to see far, it is not able to relax. The result is the eye will not be able to see distant object clearly. This is known as accommodative myopia. Transient Myopia Please see Accommodative Myopia. The word transient means temporary. Such onset myopia can be reversed with adequate relaxation for the eye. When allowed to relax their eyes for 2 to 4 weeks, the ciliary muscle spasm would usually be relieved and the eyes can see distant object clearly again. Hence temporary. Pseudo Myopia Please see Accomodative Myopia. Because its short term in nature, it is also known as pseudo or fake myopia. Axial Myopia Simply Myopia, where the eyeball shaped is enlarged or elongated(axial length), causing the image of distant objects to fall before the retina instead of on it. Neuro Myopia Also known as mild amblyopia. Although the eyeball shape is normal, and the accommodative system is functioning well, the brain is not able to receive clear image from the eye. This is due to the poor development of the visual-neuro pathway, often corrected by prescribing glasses. |
