Always wear safety goggles when coming in contact with hazardous materials, regardless of if you are at work or at home. It is best to keep a pair of these goggles in both locations, just in case you are faced with a situation where you need them. Do not take the safety of your eyes for granted.
If you want your eyes to look and feel their best, drink lots of water. The more hydrated you are, the less you will suffer from dark circles. Hydrated skin doesn't allow the blood vessels to show, ensuring that your raccoon eyes (dark circles) become a thing of the past.
Be sure to not only get your vision checked every year, but have a comprehensive exam. This often includes other tests which peer inside the eye to check for conditions such as glaucoma or even diabetes. The sooner you catch these issues, the easier it will be to treat them.
