Correction of Near and Farsightedness

Question 1

What is another name for Nearsightedness?

Answer 1

Myopia

Question 2

What is another name for Farsightedness

Answer 2

Hyperopia

Question 3

Myopia and Hyperopia can be corrected with the use of ______.

Answer 3

Lenses

Question 4

Does it matter how severe your Myopia/Hyperopia is when getting corrective lenses?

Answer 4

Yes, depending on the severity of your myopia/hyperopia, your corrective lens will have to be more or less convex/concave (this is why different people have different prescriptions)

Question 5

If you have Nearsightedness can you see close or far?

Answer 5

Nearsightedness is when you have trouble seeing distant objects, but have no trouble seeing close objects

Question 6

How does Myopia work?

Answer 6

Because the incoming light focuses to early (before the retina)

Question 7

What causes Myopia?

Answer 7

Myopia is caused by the eye being too long from front to back

Question 8

Can Myopia be corrected?

Answer 8

Yes, it can be corrected with the use of a concave lens. The concave lens spreads them out so that once they get refracted by the eye, the rays will take longer to converge, therefore causing them to converge at the exact point of the retina

Question 9

If you have Farsightedness can you see close or far?

Answer 9

Farsightedness is when you have trouble seeing close objects but have no trouble seeing distant objects

Question 10

How does Hyperopia work?

Answer 10

Because incoming light focuses too late (after the retina)

Question 11

What causes Hyperopia?

Answer 11

Hyperopia is caused by the eye being too short from front to back

Question 12

Can Hyperopia be corrected?

Answer 12

Hyperopia can be corrected with the use of a convex corrective lens. The convex lens refracts incoming light inwards so that once they get refracted by the eye, the rays will converge sooner, therefore causing them to converge at the exact point of the retina (the convex lens gives the light convergence a head start)
