The Causes of Hyperopia
Hyperopia, also known as farsightedness, is a physical condition that leads to the distortion of the cornea or lens of the eye. The cornea, which is the clear front surface of the eye, has a dome shape, while the lens is the transparent structure positioned behind the cornea. Normally, both the lens and the cornea possess a smooth curvature that helps to bend or refract the incoming light, enabling a sharp and focused image to form on the retina located at the back of the eye. However, when the cornea and lens do not have a perfectly smooth curvature, it results in a refractive error, leading to a blurred image.
Understanding the Causes of Refractive Errors
Refractive errors are a common occurrence when the cornea or lens of the eye is not uniformly curved. This irregularity leads to improper refraction of light rays, resulting in distorted or blurry images. One of the primary causes of refractive errors is hyperopia, which is characterized by a shorter than normal eye or an irregularly curved cornea. In adults with refractive errors, objects at varying distances, both near and far, may appear blurry.
