Nearsightedness is normally treated with prescription eyewear.
We use corrective lenses in spectacles. Near sight is corrected with diverging lenses and far sightedness with converging lenses.
Yes. Laser is very expensive however. A cheaper alternative is glasses or contacts.
There are a lot of visual problems like, glaucoma.cataract,nystagmus,strabismus,retinal detachment, far sightedness and near sightedness.
are conditions where a person cannot see distinctly and comfortably. There are three common eye defects, and they are(i) myopia or near-sightedness, (ii) Hypermetropia or far-sightedness, and (iii) Presbyopia. These defects are corrected by the use of suitable spherical lenses.
myopia or "near-sightedness" as most of us refer to it is an eye condition.
This question makes no sense. It is the shape of specifric parts of the eyes that determines far or near sightedness.
If a person can see things far away better than close up, this is called far sightedness. It has to do with the shape of the eye ball and the place in the eye that the image being viewed is focused in the eye. If the image focuses in front of or behind a certain point in the eye, it will cause far sightedness or near sightedness.
The wavefront surgery corrects eye vision. It is used to correct refractive errors near sightedness, far sightedness and astigmatism. It is used to give people better eye sight.
far short sight you can use concave lenses far long sight you can use convex
how does the eye respond to light rays to manifest far sightedness
The opposite to myopic/myopia is HYPEROPIC/HYPEROPIA. Myopia is also known as short sightedness or near sightedness. Hyperopia is also known as long sightedness or far sightedness. A myopic eye focuses the image before it reaches the retina at the back of the eye. This is because the eye is too strong. A myopic eye will find it easier to focus on a close up object rather than a far away object. A myopic eye needs to be corrected with a minus/negative powered prescription lens (-). A hyperopic eye focuses the image after/behind the retina as a hyperopic eye is too weak. A hyperopic eye will have problems focusing on close up objects and in some cases it won't be able to focus at any distance. A hyperopic eye will be corrected with a plus/positive powered prescription lens (+).
This problem is most likely to be caused by astigmatism(a mishapen cornea), but could also be caused by cataracts (opaque lenses), or strabismus (crossed-eyes), or some combination of these conditions with myopia (near-sightedness), or hyperopia (far-sightedness).
