Dehydrated eyes often look red, irritated, tired, and sunken, with dark circles or shadows underneath, due to reduced tear production and fluid in the surrounding tissues, causing a gritty feeling, light sensitivity, and sometimes stringy mucus or blurred vision, as the eyes lack lubrication and appear dull or hollow.
Signs and symptoms, which usually affect both eyes, may include: A stinging, burning or scratchy sensation in your eyes. Stringy mucus in or around your eyes. Sensitivity to light.
Artificial tears may be all you need to control mild dry eye symptoms. Some people need to put drops in several times a day, and some use them only once a day.
If neglected, skin dehydration can lead to rashes, cracked skin, and redness. Severe skin dehydration can cause inflammation or worse, rashes that are difficult to identify and treat.
Tricyclic antidepressants, such as amitriptyline (Elavil), block a chemical messenger in the brain. A side effect of this is decreased tear production. Selective serotonin reuptake inhibitors (SSRIs) like citalopram (Celexa) and fluoxetine (Prozac) may also cause dry eye, but generally to a lesser degree.
Common side effects
SSRIs: Paxil, Lexapro, Zoloft, Celexa, Prozac and Luvox
SSRIs can have eye-related side effects such as: Mild dry eyes. Pupil dilation (which can cause light sensitivity) Possible increased risk of cataract development.
Symptoms of dehydration
Itching (pruritus) in the body can stem from several nutrient deficiencies, with iron deficiency anemia being a common culprit, causing dry, itchy skin. Other potential deficiencies linked to itching include vitamin D, essential fatty acids, B vitamins (like B12), and minerals like calcium, zinc, and copper, affecting skin health, hydration, and histamine regulation.
If fine lines are visible at the corner of the eyes or on the cheeks, and flakes (small dead skin cells) appear after you apply make-up, your skin is most likely dehydrated.
The concept is easy to remember: Every 20 minutes, look at something 20 feet away for at least 20 seconds. This short break allows your eye muscles to relax after continuous near-focus activity, helping to prevent fatigue, dryness, and headaches.
Dry skin often responds well to lifestyle measures, such as using moisturizers and avoiding long, hot showers and baths. If you have very dry skin, your doctor may recommend a moisturizing product formulated for your needs.
The time it takes to rehydrate your eyes depends on the severity of the dehydration. If addressed early, your symptoms may improve within hours of proper hydration. However, chronic or severe dehydration may require longer recovery times and consistent care to resolve symptoms fully.
A. Yes, because when you're dehydrated, your body produces fewer tears, resulting in dry eyes. Without sufficient tears, your eyes can become irritated and your vision may become blurry. An eye doctor can recommend special eye drops or other treatments to alleviate some of the uncomfortable symptoms of dry eye.
The 10-10-10 rule for eyes is a simple strategy to combat digital eye strain: every 10 minutes, take a 10-second break and look at something at least 10 feet away, giving your eyes a rest from near-focus on screens. This practice helps prevent eye fatigue, dryness, and headaches by allowing eye muscles to relax and encouraging blinking, which is often reduced during screen use, says Healthline and Brinton Vision.
Symptoms
Here are 10 unexpected signs of a vitamin D deficiency that may surprise you.
The observed reduction in pruritus severity in our meta-analysis may be attributable to these anti-inflammatory effects, suggesting that vitamin D could be particularly beneficial for patients with inflammatory skin conditions.
Is it dehydration or something else?
Severe dehydration can lead to serious complications, including:
Medicines that make dehydration more likely are:
Results: Our analysis revealed that SSRIs were significantly associated with eye disorders, with a higher risk of vision blurred with escitalopram, angle closure glaucoma with citalopram, and photopsia with paroxetine. The most common eye disorders were vision blurred, visual impairment, mydriasis, etc.
Overall, citalopram appears to be the best-tolerated SSRI, followed by fluoxetine, sertraline, paroxetine, and fluvoxamine.
Summary of Black Box Warnings
In short-term studies, antidepressants increased the risk of suicidality in children, adolescents, and young adults when compared to placebo. Short-term studies did not show an increase in the risk of suicidality with antidepressants compared to placebo in adults beyond age 24.
