When the lens loses its elasticity and can no longer bring near objects in focus what is the condition?
Presbyopia
What is the part of a microscope brings objects into a rapid but coarse focus?
coarse adjustment knob
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)
How does the condenser focus knob work on a microscope work?
it helps look at objects up close
A telescope that uses a set of lenses to gather and focus light from distant objects?
Refracting Telescope.
What instruments use lenses or mirriors to collect and focus light from distant objects?
Telescope.
What instruments use lenses or mirrors to collect and focus light from distant objects?
A Telescope uses lenses or mirrors to collect and focus light from distant objects. With the advancement in optical research we are capable to watch the stars and planets better than before. Our information about universe largely depend on telescopes.
What part of the eye uses small muscles to change its shape so that you can focus on near or distant objects?
The lens
Definition of hyperopia?
A vision condition in which distant objects can be seen clearly, but close ones do not come into proper focus.
What part of your eye uses small muscles to change its shape so that you can focus on near or distant objects?
The lens
When the image of a distant object is brought into focus in front of a person's retina. what is the defect?
nearsightedness.
Is emmetropia farsightedness?
Emmetropia is when light is focused exactly on the retina and vision is perfect. Farsightedness is called hyperopia. This condition occurs when the eyeball is smaller than normal and light rays from near objects do not focus properly on the retina at the back of the eye. A person with hyperopia can see distant objects more clearly than closer objects.

How do you write focus in a sentence?
If you ignore distractions and focus on what the teacher is saying in class, you are likely to understand the subject better.Without my glasses, I cannot focus properly on objects some distance away.
What does it mean when someone is nearsighted?
Being diagnosed as being nearsighted means just exactly what it says. You can only focus on things close to you. Distant objects are out of focus. Being farsighted means just exactly the opposite of being nearsighted. Distant objects are in focus, but nearby things appear blurry.
What instruments use lenses or mirrors to collect and focus light from distant?
A telescope uses lens and mirrors to collect and focus light from distant object.
