Has anyone ever told you that eating carrots will help you see in the dark?This is just one of many incorrect beliefs you may have heard. Below, TEENS has picked out scientific explanations for three mistakes that people make about their eyes. Let’s take a look.
Can eating carrots improve your eyesight?
Carrots are rich in vitamin A, which helps the eyes to turn light into information for your brain. This allows people to see in darker places.However, eating more carrots won’t help you see better. A certain minimum amount will help, but a large number of carrots will not give you superhuman vision.
If your parents have bad eyesight, will you have bad eyesight, too?
Myopia(近视)can be passed from parents to children. A study by the American Optometric Association found that if both parents are myopic, there’s a 33 to 60 percent chance that their child will be. For children who have one parent with myopia, the chance is 23 to 40 percent, and it’s down to 6 to 15 percent for kids with non-myopic parents. So if your eyesight is bad, your children might still have good vision.
Do color blind people see the world in black and white?
Color blindness doesn’t usually mean that people see the world like an old movie. They usually can’t tell certain colors apart, especially green and red. Another commonly confused pair of colors is yellow and blue.Our eyes have cone cells(视锥细胞)that sense different wavelengths (波长)of light. If these cells don’t work properly, color blindness occurs.
There are different levels of color blindness. Some people are only color blind in low light.
However, in the most serious form of color blindness, everything is shades of gray.

Duncan Smith and Katie Schmidt both always wanted to be firefighters. Now, the two 16-year-olds have started their training at Wellington High School Fire Science Academy in the US.
At the Fire Science Academy, students learn how fire behaves, how to use firefighting tools, how to save people, and of course, how to put out a fire.
The academy recently received a fire truck that will help students become familiar with the trucks used by real firefighters, according to Mark Davis, a teacher at the academy.
“It’s an important part of the program,” Davis said. “It allows our students to understand the everyday tools used in the fire service. It also gives them a sense of pride to enter into public service.” The fire truck will also help students practice before taking the state firefighter test, Davis said.
Schmidt said she was interested in the opportunities the academy presented.“It was my decision to go into this program,” she said. “My dad has been in this service for almost 25 years and I wanted to follow in his footsteps and learn and understand what he goes through in his day-to-day life.”
“The academy is strict and students have to be comfortable with standing to attention for most of the day,” Davis said. “I like the discipline(纪律) aspect because I feel like a lot of high school students sometimes go the wrong way, and with this, it’s not possible,” Schmidt said.
