Reading at night is recommended for health and improved sleep, compared with staring at electronic screens. Studies show that nighttime reading can improve sleep quality, lower stress, and reduce exposure to blue light, which can disrupt melatonin.¹ Using phones, laptops, tablets, and televisions close to bedtime can make it tougher to drift off. The blue-leaning light they emit can interfere with your body’s natural “time to sleep” signals.²

A large body of scientific research backs up the claim that astaxanthin is great for your body. As a potent antioxidant, astaxanthin scavenges free radicals that cause cellular damage. This benefits many parts of the body, including your skin, eyes, and brain. What is astaxanthin? Where does it come from? And what does the latest research say about its benefits?

Astaxanthin is a Pigment that Makes Seafood Pink

Astaxanthin is a marine xanthophyll carotenoid primarily produced by microalgae like Haematococcus pluvialis. Dietary astaxanthin can be obtained through seafood, including salmon, trout, shrimp, and krill.

Brain fog means that you walk into a room and forget why you’re there. You reread the same sentence because the meaning does not sink in. Or you cannot find the words mid-conversation, even though you know what you want to say. If you are a senior who is experiencing brain fog, how can you improve it? And how does it affect your vision health?

A scientific report associated brain fog with the words “‘forgetful,’ ‘cloudy,’ and ‘difficulty focusing, thinking, and communicating’.”¹ The decreased cognitive abilities we call “brain fog” can include slow or hazy thinking, confusion, lack of motivation to exercise, difficulty concentrating, trouble remembering things, difficulty focusing, irritability, anxiety, headaches, insomnia, and low motivation.

Vitamin D is often called the “bone vitamin,” but that’s only part of the story. Vitamin D3 (cholecalciferol) also influences systems your eyes rely on every day—especially as we get older: inflammation control, immune regulation, oxidative stress protection, and even how the body manages blood vessel growth.

And here’s the real-world issue: most people don’t get enough vitamin D consistently. Food sources are limited, sunlight is seasonal and complex (plus many of us avoid it for skin health), and modern indoor life takes care of the rest.

The US Department of Health and Human Services (HHS) released its long-awaited update to the nation’s dietary guidelines on January 7, 2026, promising a “historic reset” that puts real, minimally processed food back at the center of American nutrition policy ¹. Chronic diseases like heart disease, diabetes, and obesity are high, and these guidelines aim to “Make America Healthy Again.”

On the other hand, the Mediterranean Diet is popular for its proven benefits in reducing the risk of chronic diseases and promoting long-term wellness. It focuses on plant-based meals, healthy fats, and a balanced lifestyle. At Natural Eye Care, we adapted the Mediterranean Diet specifically for people with vision issues and called it the Vision Diet. This diet includes additional recommendations on antioxidant intake, organic foods, and avoiding certain additives and fats ².

A new study has found a link between vascular diseases, specifically high blood pressure, diabetes, and increased risk for dementia. Vascular risk factors were higher in both female and Black participants, as well as non-carriers of the APOE ε4 gene, which is linked with an increased risk of Alzheimer’s.¹

The statistical results of this cohort study suggest that between 22% and 44% of incident dementia cases by 80 years old were attributed to midlife and late-life vascular risk factors.

What are the connections between caffeine, coffee and eye health? Do the negatives outweigh the positives? This is a tricky question, given the contradictory research on this popular beverage. Coffee is high in antioxidants that have broad health benefits. However, coffee is typically acidic, which can cause stomach symptoms. The caffeine in coffee is a stimulant that increases alertness, but it can also cause energy crashes. Caffeine research has not yet pinpointed the ideal amount of caffeine for better health. According to Traditional Chinese Medicine, coffee can be helpful or harmful, depending on the constitution of the drinker.

The link between cardiovascular disease and eye health may not be obvious. However, the eyes are made from nutrients. A large body of research shows how important nutrition is for eye health. Maintaining healthy vision depends on whether the eyes and visual system are properly nourished. Cardiovascular disease, including high blood pressure and atherosclerosis, can affect the flow of essential nutrients and oxygen to the eyes. Poor circulation to the eyes can cause damage to the retina’s tiny blood vessels, with potentially sight-threatening consequences. Cardiovascular disease can often be identified through retinal scans well before the disease is detectable through traditional tests.

In the USA, our diets are usually high in ultra-processed foods, fat, sugar, salt, and empty calories. Poor nutrition has been linked to declines in mental health, increasing the risk of depression and anxiety. It can also compromise eye health, contributing to conditions like glaucoma, diabetic retinopathy, cataracts, and macular degeneration. A nutrient-poor diet can also impair brain, cardiac, and neurological function, weaken immunity, and contribute to obesity.
