When you are working on a project that requires cutting wood or other materials, be sure to wear a pair of goggles. As you are cutting, particles are flying into the air. If your eyes are not protected by goggles, a piece of material can fly in and cause irritation or damage to your eyes.
Don't strain the eyes for too long. When you strain your vision and focus on something, such as a computer or television screen, you typically forget to blink as much as you should. When you don't blink enough, it means your eyes are getting the lubrication they need, which can lead to more serious problems.
