Human eye and colourful world human eye parts and power part 1

It is convex lens, Image is formed on retina

• Viterous humor

• Aqueous humor

• Crystalline eye lens

• Cornea

Outermost covering of an eye, prevents from excessive dirt and damge and light refracts through it

• Cornea

• Retina

• Rod cells

• Optic nerve

Honey like fluid, maintains spherical shape of an eye

• Aqueous humor

• Retina fluid

• Viterous humor

• None of these

Aqueous humor

• Maintains spherical shape of the eye

• Is water like fluid

• Water like fluid which balances pressure

• Honey like fluid which maintains pressure balance for the eye

Optic nerve

• Transmits photo signal to retina

• Transmits photo signals to brain

• Transmits photos to aqueous humor

• Works with honey like fluid

Function of Iris is to

• Size the pupil

• Inverts the image

• Generate the root cause for myopia

• All of the above

Ciliary muscle

• Creates myopia

• Adjusts the object distance

• Adjusts the focal length

• Is a photo sensitive screen

Pupil

• Regulates the light

• Gives vibgyor

• Regulates the light and image is formed on retina

• Regulates the light entering inside the eye

Case study;

Amanda was walking throught the garden and suddenly she saw a girl. The girl asked i) How the images are being seen through my eye? Amanda too wondered about the same. She also got one question within her mind ii) How is she able to check out the intensity of light

Everyone is able to see colours iii) Have you ever wondered how can you see colours?

• i) Her eyes have a photo sensitive screen

  ii) She is able to check intensity of light through cone cells and wbc present

  iii) She is able to sense light through Rod cells

• i) Her eyes have a photo sensitive screen

  ii) She is able to check intensity of light through rod cells

  iii) She is able to sense light through cone cells

• i) Her eyes have a photo sensitive screen

  ii) She is able to check intensity of light through cone cells and wbc and rbc present

  iii) She is able to sense light through Rod cells present in viterous humor

• All of them

Ability of eye lens to adjust the focal length axcording to various distances is called

• Power of accomodatiom

• Power of eye lens

• Power of retina

• Power of convex lens used for eye
