• The human eye blinks approximately 11,000 times per day which equals over 4,000,000 times per year!
• The eye is approximately the size of a ping pong ball that contains over 2 million working parts!
• The average healthy 20 year-old eye allows up to 3 times more light than the average 60 year-old!
• During the course of the day as your eyes adjust to different types of lighting conditions and focal distances, scientists estimate that your eyes will expend the same amount of energy that your leg muscles would expend if you walked 50 miles!
• Light travels at 186,282 miles per second. That means in the snap of your fingers, it has encricled the earth 7.5 times. When light enters your eye, your eye does 3 things with the light: It changes the speed, direction, and amount of light!
• Sometimes the eye needs help with the direction and the amount!
• When light enters one's eyes, it is focused to the back of the eye where over 130 million photoreceptor cells convert the light and the image into electrical-chemical impulses that are sent via the optic nerve to the brain to give us our perception of the world around us! The conversion of that light into electrical-chemical impulses is one of the highest metabolic activities in the human body!
• In April 2007, USA survey asks consumers, "What is your greatest health fear as most negatively impacting your life style?" Two responses tied for first: Being paralyzed and loss of vision. Yet the average person sees their dentist three times more often than their eye care professional!
• The eye and the brain, which compose 2% of our total body weight, consume 25% of nutrition!
• Over 50% of all Americans over the age of 65 develop a cataract. The odds of developing macular degeneration are 30% by age 75!
• In the USA Today, an estimated 80 million people have potentially blinding eye disease; 3,000,000 have low vision; 1,100,000 are legally blind; 200,000 are severely visually handicapped!
• There are 4 types of glare:
  1) Distracting glare- caused by reflections off of uncoated lenses
  2) Disarming glare- glare that occurs when going from indoor lighting to outdoor; bright sunlight between 3,000-10,000 lumens cause occular discomfort, squinting, reduced contrast, and slower dark adaptation
  3) Disabling glare- over 10,000 lumens are causing occular discomfort, reduced contrast, slower dark adaptation, and blocked vision
  4) Blinding glare- reflected light that blocks vision, causes occular discomfort, reduced contrast, and inhibits night vision.
  --The automobile insurance industry tells us of 18,000 reported accidents per day, in up to 6,000 accidents, 1 of these 4 types of glare is a contributing cause of the accident!

Do you have trouble reading signs at night? Have you noticed you are more sensitive to bright sunlight? This is a dual problem with light many of our presbyopic and light sensitive clients experience. This calls for a prescriptive plan of treatment--AR Coating, Photochromics, and a Polarized solution!
