What you eat is very important to the health of your eyes. A diet that is rich in vitamin A and omega-3 fatty acids are helpful to good eyesight. Many vegetables like carrots and broccoli are rich in vitamin A. Fish and nuts can provide you with the omega-3 that you need.
Keep your eyes protected when dealing with hazardous situations. In certain types of unclean or hazardous environments, you should keep your eyes protected by wearing safety goggles. These also include certain sports. Activities like lacrosse, ice hockey, or racquetball can cause eye injuries, which is why you should wear helmets that have built-in face masks or sports goggles.
Schedule an exam in the future. A lot of people simply aren't visiting their eye doctor as regularly as they should. You should have your vision checked at least once in your twenties and then twice in your thirties, but that's only if you don't have history or symptoms of vision problems.
