4 Dangerous Symptoms Your Eyes Will Indicate When You Suffer From Dehydration

Dehydration is a condition that goes unnoticed in most cases, unfortunately. This condition can cause many inconveniences, including skin problems, inflammation, infections, headaches, nasty breath, and many more . Unfortunately, people notice them too late.

But the interesting fact is that no one ever notices that dehydration affects your eyes as well.

Yup, you heard it well. Ever feel like your eyes are drying out?

You are not wrong — they do. When your body loses fluids, your eyes lose fluids too since they are filled with it. Also, blurry vision, eye floaters, and eyestrain are all common symptoms that indicate dehydration.

Let's get serious and find out more about those three problems your eyes will have to battle when dehydration occurs.

4 Dangerous Signs Your Eyes Will Experience If You're Dehydrated

As already stated, dehydration can have several unwanted effects on your body. Remember, your eyes are no exception, so let's see what you can do to prevent this.

1. Dry eyes

Dry eyes occur when your tear ducts are no longer producing enough tears to lubricate and nourish your eyeball. The result is eyes that aren't providing enough moisture to stay hydrated.

When you are dehydrated, your eyes will go dry since your body will prioritize using water for more essential processes, such as maintaining the brain's circulation. This will cause symptoms such as redness, itchiness, grittiness, excess watering, blurred vision, strained eye, and an uncomfortable feeling of foreign matter in your eyeball.

Tears also contribute to a clear vision. They wash away foreign matter such as dust and help reduce the risk of eye infection.

Dehydration will prevent your eyes from cleaning themselves because they can't produce tears. The best treatment for dry eyes is to drink plenty of water and apply eye drops that can also help by lubricating the eye and washing away foreign materials.

2. Blurred vision

Dehydration and vision distortion are often closely associated since dehydration causes eye strain, leading to blurry vision. Then blurred vision leads to headaches. Tired, blurry eyes are a symptom of eyestrain that causes vision distortion.

The eye strain will occur when you spend a lot of time in front of a screen since you will blink less while you are focused on your screen. That will be a problem since you won't produce tears by blinking, so your eyes won't be well lubricated and hydrated.

So if your job requires a lot of time spent in front of the big screen, drink enough water and use eye drops to help retain your eyes hydrated and healthy.

3. Eye floaters

Eye floaters are spots and lines in your vision that look like web or rings that move through your vision field. Age-related changes usually cause eye floaters. Dehydration can trigger this problem, too, since eye floaters can result from toxin buildup.

Eye floaters occur when the vitreous humor, a gel-like substance in your eye, loses its shape or shrinks significantly. This substance is 98% water, so dehydration will cause proteins to solidify instead of remaining dissolved.

To prevent this from happening, it is recommended to drink plenty of water and flush out harmful toxins and debris from your eyes.

4. Puffy eyes

When your body's fluid levels become low, your body will begin to stockpile as much fluid as possible. If you do not intake enough water daily, you will for sure trigger fluid retention. This will cause your body and your eyes to become puffy and swollen.

If you consume too much salt, you can expect some fluid retention that will also cause your body and eyes to dehydrate.

Puffy eyes can be very uncomfortable, and they are usually the worst in the morning. So drink plenty of water to flush out excess fluid. If this does not help, start with gentle massage to reduce swelling.


Dehydration can be nasty on your body and your overall health. I understand that sometimes it's tough to stay well hydrated and drink your recommended eight glasses of water per day since we are all swamped.
