a condition in which rays of light from distant objects are focused in front of the retina, causing blurred vision. Nasal - toward the nose.
(ophthalmology) eyesight abnormality resulting from the eye's faulty refractive ability; distant objects appear blurred
a condition in which the eye is larger than a normal eye
A refractive error where the light rays entering the eye are bent too quickly, resulting in the light rays coming to a focus infront the retina, instead of on it.
Also known as 'short sight'. A refractive error of the eye in which light is brought to a focus in front of the retina, causing distance vision to be blurred (corrected using negative lenses). Uncorrected myopia may cause problems with distance vision, for example not seeing road signs clearly when driving.
a refractive abnormality of the eye requiring a negative or concave lens for correction. A myopic eye has excess focusing power causing light rays to focus in front of the retina. Myopia causes blurred distance vision. Also known as nearsighted.
A condition where one has difficulty focusing at far distances, caused by the eye being too long.
Short sight, always causes difficulty with distance vision
When the curvature of the cornea is too steep, light rays entering the eye focus in front of the retina. The result is a blurred view of distant objects.
A condition in which images come to focus in front of the retina resulting in defective vision for distant objects. Eye may be to big or focusing too weak.
common refractive defect of vision
Not being able to see objects at far away distances.
When the unaided eye can only focus on close objects. itrogen Purging. Filling an instrument (particularly an outdoor one such as a binocular or riflescope) with zero grade or almost pure nitrogen in order to exclude all moisture and oxygen and so virtually prevent subsequent fogging and oxidation of the optics bject Lens. The front lens, in an instrument, closest to the object being observed.
the eyes can focus very near but cannot focus in the distance.
the inability to see distant objects clearly.
also known as near or shortsightedness; condition in which rays of light from distant objects are focused in front of the retina, causing blurred vision.
a condition where an individual cannot see objects six metres from the eye clearly. It is also known as short-sightedness.
refractive error in which the focal point for light rays from a distant object is anterior to the retina when accommodation is at rest
Also known as "short-sightedness". Means that you can only see near objects clearly. Don't take it figuratively: having myopia doesn't mean you are obsessed with the present and can't plan ahead. That is baloney! Traditional explanation: the eyeball is too long.
Also known as short-sightedness. A focusing error in which the eye is too long or the cornea is too curved. The cornea and lens focus light in the middle of the eye in front of the retina. Defocused light reaches the retina, resulting in blurred vision.
Also known as "Short-sightedness". It is a condition where near objects are seen clearly but distant objects appear blurred. It can occur when the eyeball is longer than normal.
Condition in which the length of the eye is too long or the cornea is too curved, causing light rays to focus in front of the retina instead of on it. This results in blurred distance vision.
A refractive abnormality of the eye requiring a minus (negative or concave) lens for correction. Synonyms: near sighted or short sighted. People who are near sighted can see objects up close or at near without glasses. - Go to top
the long (from front to back) eyeball frequently results in short-sightedness (myopia). Back to the top
Refractive error related to either a steep, or pointed cornea, or an eye of greater than usual length. The optical effect is that near objects are clearer than distance ones.
The ability see near objects more clearly than those at a distance.
Vision disorder characterized by a decrease in long-distance visual acuity. The eye is too long so the image forms in front of the retina making far-off objects blurry. Myopia affects about 20% of the population. ( myopie, n.f).
Short-sightedness. It is easier to see close up than in the distance.
Myopia is the result of either an eyeball that's too long, or a too powerful focusing mechanism which causes light rays to focus in front of the retina. The result is that people have trouble seeing objects in the distance.
SHORTsighted; enhanced ability to see close objects, inability to focus on distant objects. This occurs when one's eyeball is too long or too big for the focusing system of the eye, or when the eye's focusing mechanism is too strong (excess positive diopter), thus causing light rays to focus in front of the retina, making far objects appear blurry. A negative diopter lens is required to achieve normal vision.
A refractive error in which the eyeball is too long or the lens system of the eye is too powerful causing light rays to focus in front of the retina. Can be corrected with concave or minus (-) lenses. Go to top of page
That refractive condition of the unaccommodated eye where parallel incident rays of light tend to focus at a point in front of the retina.
