Optics and Vision Science Quiz

Colour blindness is a condition where one or more colour cone cells are not functioning properly, making red and green appear similar.

Accommodation is the adjustment of the lens shape by ciliary muscles to focus on objects at varying distances, ensuring the image is clearly projected onto the retina.

Hyperopia, or farsightedness, is when nearby objects appear blurry because light focuses behind the retina; it is corrected using a converging lens.

<p>Presbyopia is the condition where the eye's lens becomes less elastic with age, making it difficult to focus on nearby objects.</p> Signup and view all the answers

<p>Myopia, or nearsightedness, is when distant objects are blurry as light focuses in front of the retina; it is corrected with a diverging lens.</p> Signup and view all the answers

<p>The formula is n = c/v, where n is the index of refraction, c is the speed of light in vacuum (3.00 x 10^8 m/s), and v is the speed of light in the medium.</p> Signup and view all the answers
