Eyesight Trivia: Can you pass our “Vision” Test? (Part 2)

By Cornea Associates of Texas on March 01, 2015
Let's take another Eyesight Trivia Test to see how much knowledge you have on eyes!

True or False: Using a nightlight in my child’s room can contribute to nearsightedness. This is false. While it once was thought that it could, it has mostly been debunked by lack of evidence. It’s even been suggested that a nightlight may actually help him or her learn to focus and develop important eye coordination skills while he or she is awake. 
True or False: Reading in the dark will not weaken my eyesight. This is true. As with sitting too close to the television, you may get a headache or eye fatigue from reading in the dark, but it will not deteriorate your vision. 
True or False: Using glasses or contacts will make me dependent on them or weaken my eyesight. This is false. Over time you’ll find changes in your vision due to aging or the presence of disease, but it is not because of your current prescription. Due to genetics and other variables, change will continue despite wearing glasses earlier or later in life, or more or less often.
True or False: Wearing the wrong prescription can damage your eyes. This is false. You may get a headache if you wear the wrong prescription for very long, but it won't harm your vision. Eye strain may also start to occur if you are wearing an old prescription. To see your best, make sure to keep up with your yearly eye exams to have the prescription that's right for you.

True or False: As long as you can see well, you don’t really need a vision exam. This is false. An eye exam is more than just checking for a glasses or contacts prescription. Your doctor will check the general health of your eyes and screen for possible impending eye diseases or complications. They can also see signs of other severe health conditions such as diabetes, high blood pressure, and high cholesterol. Make sure to see your eye doctor every year to keep tabs on your health!
True or False: There are a number of things I can do to prevent vision loss. This is true. Seeing your eye doctor at the very first signs of vision loss, such as distorted vision or flashes of light, is one way of preventing such loss.  Depending on the cause, there are treatments that can stop, slow, or reverse most causes of vision loss, if detected early enough.  Routine eye examinations are one of the most important ways to conclude if any of problems exist or if any treatment is necessary. There are also lifestyle issues that can affect vision. Not wearing proper safety eye wear during certain activities, smoking, and nutritional deficiencies put you at risk vision loss. 
True or False:  If parents have poor eyesight, their kids will more in likely inherit that trait. This is true. Eye conditions such as glaucoma or dependency on glasses for good vision may be a trait passed on to your child.

True or False:  Boys have a higher probability of being color-blind compared to girls. This is true. It's probable that up to 8% of boys have some extent of color blindness, while less than 1% of girls do. This is because the predisposition for color deficiency lies on the Y chromosome.
