refractive errors are: myopia (nearsightedness): difficulty in seeing distant objects clearly; hyperopia (farsightedness): difficulty in seeing close objects clearly; astigmatism: distorted vision resulting from an irregularly curved cornea, the clear covering of the eyeball. presbyopia: which leads to difficulty in reading or seeing at arm's length, it is linked to ageing and occurs almost universally. refractive error treatment Refractive errors cannot be prevented, but they can be diagnosed by an eye examination and treated with corrective glasses, contact lenses or refractive surgery. If corrected in time and by eye-care professionals, they do not impede the full development of good visual function. Correction is provided in different forms according to the defect, the age f the person, the requirements in terms of work of activity performed. WHO estimates that 153 million people worldwide live with visual impairment due to uncorrected refractive errors. This figure does not include the people living with uncorrected presbyopia, which is likely to be quite significant, according to some early evidence. WHO, its Member States and partners are working to find ways to provide good quality, professionally prescribed, local, affordable corrective refraction services to people in need, especially in poor areas with limited eye care services.

An eye care professional who has examined the patient’s eyes and is familiar with his or her medical history is the best person to answer specific questions. Refractive Errors Defined What are refractive errors? Refractive errors occur when the shape of the eye prevents light from focusing directly on the retina. The length of the eyeball (longer or shorter), changes in the shape of the cornea, or aging of the lens can cause refractive errors. What is refraction? Refraction is the bending of light as it passes through one object to another. Vision occurs when light rays are bent (refracted) as they pass through the cornea and the lens. The light is then focused on the retina. The retina converts the light-rays into messages that are sent through the optic nerve to the brain. The brain interprets these messages into the images we see. Frequently Asked Questions about Refractive Errors What are the different types of refractive errors
