eight reasons why your eyes are amazing

• After your brain, your eyes are the most complex organs in your body.
  
  
• Every hour, your eyes can process 360 000 pieces of information.
  
  
• In an average lifetime, your eyes will see almost 24 million images.
  
  
• For their size, the external muscles that move your eyes are the strongest muscles in the human body.
  
  
• On average, you blink 17 000 times a day.
  
  
• Including the actions of squinting, winking, crying, laughing, raising an eyebrow and blinking, you experience more than 85 000 muscle contractions in your eye area everyday.
  
  
• The skin around your eyes is 7 times thinner than that on the rest on your face and is therefore is more prone to wrinkles and crows' feet or expression lines.
  
  
• Your pupils not only dilate or contract to let in light but also react to what they see. They will enlarge when you are faced with something pleasant and shrink when you see something you find unpleasant.

Progressive addition lenses (PALs) are used to provide eyeglass wearers with a spectacle lens in which optical power varies smoothly as the user looks through different regions of the lens. For example, when looking straight ahead there may be little added power, and when looking down at some angle there may be significant power. This means the same eyeglass can be used for both driving and reading.
