An abnormal condition of the eye in which, through shortness of the eyeball or fault of the refractive media, the rays of light come to a focus behind the retina, making vision for distant objects better than for near objects; farsightedness; -- now most commonly called hyperopia. Cf. Emmetropia.
condition in which visual images are focused behind the retina with resulting defective vision of near objects; farsightedness
(farsightedness, sometimes called hyperopia) the inability of the eye to focus clearly on near objects. The lens is too flat or the eyeball is too short resulting in the image forming behind the retina.
A refractive error where the light rays entering the eye are not bent rapidly enough, theoretically resulting in the light rays coming to a focus behind the retina, instead of on it.
Also known as 'long sight'. A refractive error of the eye in which light is brought to focus behind the retina (corrected using positive lenses). Uncorrected hypermetropia may cause problems with near work, for example headaches when reading. Significant, uncorrected hypermetropia in childhood may cause other more serious problems.
also known as hyperopia or far- or long-sightedness; refractive error in which parallel light is focused behind the retina.
also referred to as farsightedness, this is a condition in which the eyeball is too short or the cornea is too flat, resulting in the inability to see objects up close. [back to the top
Also called hyperopia. Longsight; eyeball is too short for accommodating power of lens and light cannot be sharply focused on the retina. Corrected by convex spectacle lens.
