What is Myopia? Myopia is a visual impairment caused by a defect in the refraction of light in the eye. Normally, the cornea and lens focus the incoming light on the retina, providing a clear image. However, in myopia, light is focused in front of the retina and distant objects appear blurred. This can be caused by anatomical features such as the cornea or lens being too curved or the eyeball being longer than normal. Causes of Myopia [...]
What is Astigmatism and How Does It Occur? Astigmatism is a refractive error that causes blurred vision due to focusing problems in the eye. Irregular curvatures of the cornea or lens in the eye cause light not to focus properly. Astigmatism can be accompanied by other vision problems, such as myopia (nearsightedness) or hyperopia (farsightedness). Astigmatism can be combined with such refractive errors [...].
