Access Class 10 Science Chapter 10 - Human Eye and Colourful World Notes

  • Cornea: Transparent membrane covering the front of the eye; allows light to enter.

  • Aqueous Humour: Fluid behind the cornea.

  • Iris: Dark-colored, muscular diaphragm behind the cornea with a central opening called the pupil; controls light entry by adjusting the pupil size.

  • Pupil: Black due to no light reflection; size regulated by the iris.

  • Lens: Convex lens made of a transparent, jelly-like material; changes curvature and focal length with the help of ciliary muscles.

  • Ciliary Muscles: Hold the lens in place and adjust its curvature for focusing.

  • Retina: Light-sensitive membrane at the back of the eye; contains rods and cone cells that send electrical signals to the brain via the optic nerve.

  • Vitreous Humour: Fluid filling the space between the retina and the lens.

  • Image Formation: Light is focused by the lens to form an inverted image on the retina; signals are sent to the brain for image interpretation.

  • Accommodation: Ability of the eye to focus on objects at varying distances.

  • Range of Vision: Distance between the near point and far point of vision.

  • Color Vision: Cone cells in the retina detect colors in bright light; rod cells function in low light but don’t distinguish colors.

Defects of Eye

  • Colour Blindness: Difficulty in distinguishing between certain colours, often due to genetic factors. It arises when cone cells in the eye have reduced or absent pigments for red, green, or blue light.

  • Nyctalopia (Night Blindness): Inability to see in low light; can be congenital, due to injury, malnutrition, or Vitamin A deficiency. It involves issues with rod cells in the retina that are responsible for low-light vision.

  • Cataract: Clouding of the eye's crystalline lens, leading to decreased vision and yellowing of the lens. Causes include UV rays, radiation, and protein denaturation, which affect color perception and vision clarity.

  • Hypermetropia (Farsightedness): Difficulty seeing close objects clearly while distant vision remains clear. Light rays focus behind the retina rather than on it.

  • Myopia (Nearsightedness): Difficulty seeing distant objects clearly. Light rays focus in front of the retina, causing clear near vision but blurry distance vision.

  • Astigmatism: Distorted vision caused by light rays not meeting at a common focus. It can result in blurred vision for both near and far objects and may accompany hypermetropia or myopia.

  • Presbyopia: Age-related condition where the lens becomes hard, making it difficult to focus on close objects. Common in individuals over 50 and can affect those with myopia.
