When someone’s eyes look at something, the light rays come together or focus inside your eyes. If someone has perfect vision, the rays focus directly on the surface of the retina. Since the retina is curved, the image must curve and shrink. The job of both the pupil and the cornea is to shrink, curve and focus the image. If there are any irregularities, then the person’s vision will be blurry. Nearsighted people can’t see images that are far away because the light rays come into focus in front of the retina. It is the opposite for people who are farsighted. Prescription eyeglasses in Lake Success can help with that. The light rays come into focus behind the retina in farsighted people because of the shape of their eyes. This causes objects that are near to be out of focus. Astigmatism is a condition in which the curvature of the eyes is irregular, resulting in a second focal point within the eye. This causes them to have blurry vision. Refraction errors such as Nearsightedness, farsightedness, and astigmatism can all be corrected with prescription eyeglasses. Eyeglass lenses are a curved piece of glass in which the curvature bends the light rays as they come near your eye helping the rays to focus directly on the retina instead of in front of or behind it. lenses, which curve slightly, are used for nearsighted people.
