How Glasses Work to Correct Vision

You may have to wear glasses. How do they work? When you are farsighted ( hyperopia) objects far away are clear but object close appear blurry. This type of problem can be fixed with a convex lens. A concave lens is used to fix the opposite problem created when you are nearsighted.

Question:
If I used glass that correct farsightedness do I lost the nearsightedness? Or I can keep see both when using an eye glass with farsightedness?

what would happen to the light if you would put the farsighted lens in front of a nearsighted eye?

[@Rachanasravya]

You are marvelous

[@princessazab5645]

Sir
But sometimes, the convex lens forms an inverted image. How is it corrected in glasses

[@hydeemabignay7309]

What about the astigmatism?

[@R3cce]

Basically with astigmatism there will be multiple focus points. One focus point might be on the retina while the other focus point is not. Another example of how this would affect your vision is vertical lines would be in focus while horizontal lines are not.

[@raffydc1846]

How about the grade

[@Motorsports_3]

What if I see blurry close and far

[@R3cce]

That is a common symptom of astigmatism, which basically means the cornea is more oval shaped instead of being perfectly spherical

[@R3cce]

Basically with astigmatism there will be multiple focus points. One focus point might be on the retina while the other focus point is not. Another example of how this would affect your vision is vertical lines would be in focus while horizontal lines are not. The irregular cornea will bend light more strongly in one direction than another, creating blurry vision both near and far

[@kazumasatou6256]

And what if you have both high beams and low beams screwed? Cuz thats me.

Glasses can correct astigmatism with a special type of lens. Cylindrical lenses

Would you rather be short-sighted or far-sighted?

[@lexiemin6697]

Short-sighted :D
And I AM short-sighted and just got glasses. Idk why I prefer to be short-sighted honestly

[@lexiemin6697]

@@MuddyTwoShoes Actually same but ot also depends on how bad nearsighted you are. I don't know if you go to school but even when I sit in the first row i can't read the board haha. Or i can't see faces clearly... sure I can recognize people but I can't see facial expressions
