That refractive condition of the eye in which the rays of light are all brought accurately and without undue effort to a focus upon the retina; -- opposed to hypermetropia, myopia, and astigmatism.
Normal condition of the eye when light focuses correctly on the retina
(em-uh-TROH-pee-uh): Refractive state of having no refractive error. Images of distant objects are focused sharply on the retina without the need for either accommodation or corrective lenses.
the ideal optical condition of the eyes
no refractive error, where light coming from a distant object and entering the eye focuses upon the retina while the crystalline lens in its most relaxed (thinnest) state
Absence of refractive error (ie. 20/20 vision).
This is the term for a normal eye with no short- or long-sightedness. An eye with zero dioptre or degree.
is the ideal state of the eye in which no refractive error is present
(ophthalmology) the normal refractive condition of the eye in which there is clear focus of light on the retina
Perfect eyesight. Warning: if you are emmetropic, leave in 5 seconds or this web site will explode.
having perfect distance vision without the need of lens correction. The ophthalmic term for a normal eye in which light rays focus correctly on the retina, that is, there is no nearsightedness, farsightedness or astigmatism.
(the normal eye) — light focuses precisely on the retina, and near and far objects are seen clearly.
Perfect 20/20 vision, no need for glasses, contacts or any other vision correction.
A condition in which there is no measurable refractive error; a near perfect focus of the eye
no refractive errors
the condition of the normal eye where light rays from distant objects are focused on the retina so that vision is sharp and clear (20/20).
The scientific term for normal vision. When the cornea and lens of the eye focus an image directly on the retina, clear vision is the result.
Light entering the eye focuses exactly on the retina creating a sharp image. In this situation, no glasses are required for correction.
The state of an eye without refractive error in which visual acuity is at maximum for distant vision without accommodative effort.
The condition of an eye with normal vision, meaning that light rays correctly are focused at the inner back of the eye ( retina) where images are processed.
The ophthalmic term for a perfect refractive state - no nearsightedness, farsightedness or astigmatism.
a condition generally known as “normal vision” where light rays from distant objects are focused on the retina so vision is sharp and clear (20/20). (Ref: Contact Lens Council)
another term for what is perfect vision, whereby the eye focusses the image onto the retina, rather than in front of behind it (as opposed to hyperopia and myopia)
The term applied to the vision status of an individual when the eye is properly shaped and has "perfect" distance vision without correction.
Refractive condition in which no refractive error is present and distant images are focused sharply on the retina with no need for corrective lenses. Perfect vision or 20/20.
A condition in which light rays focus correctly on the retina, without using corrective lenses; same as 6/6 vision.
the state of normal vision
The refractive condition of the normal eye with no refractive error, vision is normal as objects are in sharp focus on the retina.
No refractive correction required.
The theoretical condition of an eye in which no refraction is present.
