From an early age, optometry has been imperative due to a family history of vision related problems…

Blown to Bits – 15 points each No, it shouldn’t be illegal to encrypt data. It should be legal because the Government shouldn’t have an automatic right to read anyone’s private messages/information at any time.

respond most strongly to red light, while 32% are responsive by green light. Another 2% respond strongest to blue light. When light from the banana hits the cones, it stimulates them to varying degrees. The resulting signal is transmitted along the optic nerve to the visual cortex of the brain, which processes the information and returns with a colour: yellow. The whole process takes a fraction of a second. Wow! We are truly wonderfully made (Psa…
