Question Discussion & Solution

• Vitamin is an organic non-protein substance that is required by an organism for normal metabolic function but cannot be synthesized in sufficient quantity by that organism. 
• These can be divided into two categories: fat-soluble and water-soluble.

Fat-Soluble vitamins

• Fat-soluble vitamins are soluble in fats.
• They are absorbed by fat globules that travel through the small intestines and into the general blood circulation within the body.
• Unlike water-soluble vitamins, fat-soluble vitamins are stored in the body when they are not in use.
• Vitamin A, D, E K are fat-soluble.

Water-soluble vitamins

• Water-soluble vitamins dissolve in water, which means these vitamins and nutrients dissolve quickly in the body.
• Unlike fat-soluble vitamins, water-soluble vitamins are carried to the body’s tissues, but the body cannot store them.
• Any excess amounts of water-soluble vitamins simply pass through the body
• Vitamin B and Vitamin C are water-soluble.

Key Points

• Nearsightedness (myopia) is a common vision condition in which you can see objects near to you clearly, but objects farther away are blurry.
• It occurs when the shape of your eye causes light rays to bend (refract) incorrectly, focusing images in front of your retina instead of on your retina.
• A Concave lens (diverging lens) is used by people suffering from myopia.

Additional Information 

• Far-sightedness, also known as long-sightedness, hypermetropia, or hyperopia, is a condition of the eye where distant objects are seen clearly but near objects appear blurred.
  • This blurred effect is due to incoming light being focused behind, instead of on, the retina wall due to insufficient accommodation by the lens.
• Night blindness is a type of vision impairment also known as nyctalopia.
  • People with night blindness experience poor vision at night or in dimly lit environments.
  • Although the term “night blindness” implies that you can't see at night, this isn't the case.
