Blinking: On average, a person blinks 15 to 20 times per minute, which is about 1,200 times per
hour. By spreading tears across the surface, blinking helps keep the eyes moist and safe.
eye Patterns: Just like fingerprints, eye patterns are unique to each person. This trait is used in
iris recognition devices, which are biometric ways to identify people.
Eye Color: The amount and location of a pigment called melanin in the iris determines the color
of your eyes. Blue eyes have less melanin than brown eyes do. Green eyes are caused by
different amounts of melanin and the way light is scattered.
Production of Tears: Tears do a lot of things, like keep the eyes moist, lower the risk of illness,
and get rid of foreign particles. A person usually sheds about 10 ounces (300 mL) of tears each
day.
Night Vision: It takes about 20 to 30 minutes for the human eye to get used to going from bright
light to total darkness. This process is called “dark adaptation,” and it helps us see better when
there isn’t much light.
20-20-20 Rule: Following the 20-20-20 rule can help reduce eye strain caused by staring at a
screen for a long time. Take a 20-second break every 20 minutes and look at something that is
at least 20 feet away.
Eyelashes are a very important part of keeping your eyes safe. They help keep dust and other
small things out of the eye and cause the eyelids to close when something gets too close.
Eye exercises: Like other muscles in your body, your eyes get stronger when you work them
out. Eye movements, like looking at things far away or rolling your eyes in different directions,
can help make your eyes more flexible and relieve eye strain.
Sun protection: The sun’s ultraviolet (UV) rays can hurt your eyes and make you more likely to
get cataracts, macular degeneration, and other eye problems. You can protect your eyes from
these harmful effects by wearing sunglasses that stop 100% of UV rays.
Eye Donation: After a person dies, their corneas can be given and put into the eyes of someone
else to help them see again. Corneal grafts are often successful and can make a big difference
in the quality of life for people who have trouble seeing.
