Does positive meniscus lens correct myopia?
Nope, a negative meniscus lens corrects myopia. Positive meniscus corrects hyperopia.
What type of lens would be needed to correct myopia concave or convex?
It would be concave lens. This is because it diverges the light before it enters the eye.
The far point of myopia person is 85 cms in front of the eyes what is nature and power of the lens required to correct the vision?
The defect the person suffers from is myopia. 1/f=1/u+1/v 1/f=1/-85-1/infinity f=-85 cm =-0.85 m The power of the lens=1/f =1/-0.85 =-1.176 D Concave lens have negative focal length and are used for myopia. Thus the the lens that should be used to correct this defect is a concave lens of -1.176 D.
The eye doctor tells you that the lens of your eye is a bit too strong and your eyeball is a elongated She will probably prescribe glasses for you that will correct?

How can a myopia be improved?
by use of a diverging lens
What does concave lens do?
A concave lens is a lens that possesses at least one surface that curves inwards. It is a diverging lens, meaning that it spreads out light rays that have been refracted through it. A concave lens is thinner at its centre than at its edges, and is used to correct short-sightedness (myopia). The writings of Pliny the Elder (23-79) makes mention of what is arguably the earliest use of a corrective lens. According to Pliny, Emperor Nero was said to watch gladiatorial games using an emerald, presumably concave shaped to correct for myopia.

What must you do to keep our eyes free from myopia?
It is impossible to keep from developing myopia (near sight). It is easy to correct with glasses, contacts, LASIK, PRK, or lens replacement. Myopia usually starts to develope in early childhood and almost always increases as the child continues to grow. You would have to stop the growth process to stop the increase in myopia.
What types of physiologic myopia are there?
may include refractive myopia (the cornea and lens-bending properties are too strong) and axial myopia (the eyeball is too long)
What are characteristics of marketing myopia?
This question refers to the sales and advertising for the treatment of myopia. Myopia treatment are nationally marketed by the trademarks of Lasik vision correction and INTACS lens inserts.
Can a person have both myopia and hypermetropia?
it is possible for a person to have both myopia and hypermetropia(hyperopia).The defect can be corrected by using bifocal lens.
