Does focal vision identify specific objects?
Focal vision
Focal distance of a concave lens is always what?
To my understanding of psychology, the lens convexity in distant vision is increased in order to better take in the visual stimuli. To focus visual stimuli on the fovea (focus point) of the retina, the lens undergoes a process of adjusting called "accommodation," and it becomes more convex to ensure that distant objects reach the retina. A failure to properly accommodate leads to nearsightedness (faraway objects falling short of retina) or farsightedness (nearby objects falling past retina)
Lenses are engineered to have specific focal lengths Besides the curvature of the two sides of a lens what determines the focal length?
The material that the lens is made from.
What is focal deficit?
A focal deficit is a specific area in which normal function isn't present. For example, if you had a headache during which you couldn't see in your right visual field, you'd have a focal deficit. If you had Bell's palsy and couldn't raise your eyebrow or smile normally, you'd have a focal deficit.
This type of emphasis creates a focal point by placing a specific part of an artwork alone.?
isolation
Does focal vision identify specific objects?
Focal vision
The vision area that allows you to read and identify distinct objects is?
Focal or Focus Vision
Compare nearsightedness and farsightedness in terms of defects?
In nearsightedness, the eyeball is elongated and the focal point thus falls short of the retina. This results in good vision for objects very close to the face, but poor vision at any significant distance (even beyond a few feet, for any level of nearsightedness. Conversely, in farsightedness, the focal point is never reached, before the retina. Thus, objects which are near cannot be seen clearly. However, distance sight is preserved.
What is no focal pathology?
focal meaning center so there is no specific pathology in the central area of the disease
Do near objects have a longer focal length?
Focal length is related to the lens. It has nothing to do with how near or far the object is to the lens or objective.
What are bificals more commonly known as?
eyeglasses having two focal lengths, one for near vision and the other for far vision.
Eye has fixed focal lengthThen how can you say that the focal length of changes?
The eye has variable focal length, its lense varies with thickness in order to focus to distant or nearby objects. Focal distance is constant, from lense to retina.
This type of emphasis creates a focal point by placing a specific part of an artwork alone?
Isolation creates a focal point by placing a specific part of an artwork alone.
How do you spell focial?
FACIAL : pertaining to the face FOCAL : having to do with "focus", usually in vision or photography

Do the objects size change when its placed at the focal length of the concave mirror?
The objects size is not going to change. The image size, however, would.
Define power of accomodation of the eye?
The difference of the near point and far point of vision of the eye. D= 1/Op - 1/Or The difference of the near point and far point of vision of the eye. D= 1/Op - 1/Or
