If you suffer with red puffy eyes a lot, consider reducing your sodium intake. Unfortunately, the salt we enjoy on our food isn't all that good for our bodies, including the eyes. Try switching to sea salt instead, or using other herb and spice mixtures that contain no sodium at all. Your eyes should improve quickly.
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.
If you start to see more floaters or flashes, see your eyecare professional right away. These may be signs of some deterioration in your eyes. If these go unheeded, it can lead to blindness as you get older. If the conditions are caught early, your eyecare professional can prescribe treatment that can reverse the deterioration.
Staring at a computer can cause a lot of strain on your eyes, which can lead to a number of issues, such as migraines, dry eyes, and difficulty seeing. This is why you need to take proper precautions when you know you are going to be on the computer for awhile. Be sure your computer is at a position in which your eyes are on the same level as the monitor and if possible, wear glasses.
