You might experience an itchy feeling on the eye’s surface but that’s it.

In most cases, you should just wait a week or two for the eye to heal. One exception is when the eye’s blood vessels keep breaking. Another one is if you have other kinds of bleeding. In these cases, you should speak to your doctor.

Tips for Healthy Eyes

While broken blood vessels in the eye isn’t a serious condition it still means your eyes have been injured. You can take some steps to boost your eyes’ health including the following:

1. Exercise more

This might seem to have nothing to do with eye health but it’s critical. For example, exercise increases blood flow throughout your body. That, in turn, helps to boost oxygen levels to your eyes and get rid of toxins.

2. Sleep more

Like other body parts, it’s important for your eyes to get enough rest. Make sure you sleep enough at night so you feel rested in the morning. When possible try to get 7-9 hours of sleep every night.

This will help to recharge your body including the eyes. On the other hand, if you don’t get enough shut-eye it can put more strain on your peepers during the day and cause them to look bloodshot.

3. Wash hands

This will help to prevent dirt and bacteria from entering the eye. Just like rubbing your eye this is a common yet avoidable step you can take to protect your eyes.

4. Wear sunglasses

Make sure to wear ones with good UV protection. This will help to filter out UVA, UVB, and UVC rays. You should definitely avoid “cheap sunglasses” since it can actually trap the UV rays between your eyes and the lenses, which can be worse than wearing no sunglasses.

5. Eat healthily

Make sure to pick foods that are high in Vitamins A and C, and others that are high in antioxidants. Some good options are fish, carrots, citrus, and green leafy veggies.

Another good option is fatty fish like sardines, anchovies, herring, and salmon. These foods are high in omega-3 fatty acids. This nutrient is important for central vision. Vitamin C can also help to speed up recovery from a broken blood vessel in the eye.
