Yes, drinking plenty of water is crucial for healthy eyesight because it keeps eyes hydrated, preventing dryness, irritation, and blurred vision caused by dehydration, though it won't correct refractive errors like nearsightedness; it supports the eye's tear film and overall function, reducing discomfort and potential long-term issues like dry eye syndrome. Adequate hydration ensures proper tear production and helps deliver nutrients, optimizing visual clarity and comfort, so staying hydrated is a key part of overall eye care alongside good nutrition.
Hydrating your body with water is an essential practice for maintaining healthy eyes and overall well-being. By prioritizing hydration, you support the optimal functioning of your visual system, reduce the risk of dry eyes, and contribute to clear and vibrant eyesight.
Staying hydrated carries a host of health benefits—it helps us maintain a normal body temperature and blood pressure, flushes out toxins, regulates our gut health, and cushions our joints. It also helps the body keep a delicate balance of sodium, vitamins, mineral, and hormones, among other important nutrients.
Dehydrated eyes may struggle to produce enough tears or to maintain a protective tear film. Over time, this can lead to discomfort, blurred vision, and increased light sensitivity.
If you have blurred vision, the things you see will not look sharp and clear. Blurred vision can be caused by different eye conditions, medical conditions or even medicines. Treatment for blurred vision can include eye drops, glasses, contact lenses, laser eye surgery or medicines.
Can Blurred Vision Go Back to Normal? The possibility of blurred vision returning to normal is dependent on the underlying cause. If the blurriness is a result of temporary conditions such as eye strain, dehydration, or a side effect of certain medications, it may be possible to restore your vision.
The main symptom of vitamin A deficiency is vision loss and blindness. Vision loss often begins as a problem adjusting to seeing in the dark, or night blindness. People with night blindness do not see well in the dark. But they can see normally if enough light is present.
When your fluid level drops, your eyes struggle to produce enough tears to lubricate the outside surface of the eye. If you don't drink enough water throughout the day, your eyes may feel dry and might itch, burn, or look red.
Often, it's something minor, such as debris, dry eyes, or minor irritation. More serious causes include retinal issues, infections, or eye inflammation. We recommend getting urgent medical advice if the blur is sudden, severe, or accompanied by pain. Contact your optician as soon as possible for advice on what to do.
Symptoms of dehydration
The signs you're drinking enough water include: You'll urinate more. You'll feel less hungry and may even lose weight. You'll probably experience more comfortable digestion (less heartburn).
You've probably heard the advice to drink eight glasses of water a day. That's easy to remember, and it's a reasonable goal. Most healthy people can stay hydrated by drinking water and other fluids whenever they feel thirsty. For some people, fewer than eight glasses a day might be enough.
The 1-2-3 drinking rule is a guideline for moderation: 1 drink per hour, no more than 2 drinks per occasion, and at least 3 alcohol-free days each week, helping to pace consumption and stay within safer limits. It emphasizes pacing alcohol intake with water and food, knowing standard drink sizes (12oz beer, 5oz wine, 1.5oz spirits), and avoiding daily drinking to reduce health risks, though some health guidance suggests even lower limits.
Drinking orange juice can reduce the risk of macular degeneration by up to 60% This is due to the flavonoids oranges possess that offer anti-inflammatory and immune system benefits. Carrot Juice is a great source of beta-carotene that is a vitamin which is one of the most powerful antioxidants!
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.
Superior eye health stems from a healthy diet. Make sure you're getting plenty of nutrients such as omega-3 fatty acids, zinc, lutein, vitamin C, and vitamin E. Reach for green, leafy vegetables such as kale or spinach and try to incorporate salmon, tuna, or other types of oily fish into your diet.
Fluctuating blood sugar levels—whether you have diabetes or not—can temporarily affect the shape of your eye's lens, causing unexpected vision changes. For some people, this can lead to moments of improved sight or even make glasses feel less necessary.
If your healthcare provider has evaluated your blurry vision and is treating any underlying disease, you can try the following to help with blurred vision at home:
Early signs of an eye stroke (retinal artery occlusion or ischemic optic neuropathy) typically involve sudden, painless vision loss or changes, most often in only one eye, including blurred vision, blind spots, floaters, or a dark shadow covering part of your sight. It often happens upon waking and is a medical emergency requiring immediate attention to potentially save sight and identify a risk for a full stroke.
For most people, dehydration is the much greater issue. However, if you suspect you may be overhydrated, look for symptoms like cloudy thinking, nausea and vomiting, muscle weakness, spasms or cramps and headaches. In severe cases symptoms could include mental confusion, seizures, unconsciousness and even coma.
The time it takes to rehydrate can vary depending on how mildly or severely dehydrated you are. If you are experiencing mild dehydration, the body can rehydrate in 45 minutes with around 600mL of water. For more severe dehydration, it can take longer and will usually require medical attention.
Reducing alcohol consumption can lead to brighter, more comfortable eyes and better overall eye health. If you notice any changes in your eyes, seek a thorough examination promptly.
Taking too much vitamin D leads to calcium buildup (hypercalcemia), causing physical signs like nausea/vomiting, fatigue/weakness, frequent urination & excessive thirst, constipation, and confusion/disorientation, alongside potential bone pain or kidney stones, often from supplements, not sun exposure.
Vitamins A, C and E are not the only types of nutrients with antioxidant properties beneficial to the eyes. Compounds such as carotenoids and flavonoids and the mineral selenium are also helpful nutrients to target in your diet for healthy eyes.
