The Chemistry of the Starry Night: Did Van Gogh See the World Through a Yellow Filter?
Van Gogh's yellow late works, from sunflowers to Starry Night's haloed stars, match digitalis toxicity linked to his doctor's favoured foxglove remedy. No prescription confirms this, so xanthopsia or deliberate choice remain equally plausible.
Entering the Mind of Van Gogh: Why the Tallinn VR Exhibition Reveals the Brain's Ultimate Superpower
Vision is active construction, as Tallinn's Van Gogh VR show (until Jan 10, 2027) reveals. Eyes send raw signals; the brain builds the scene from memory, emotion and expectation.
Passed the School Eye Test but Still Struggling? Why Basic Screenings Miss 75% of Vision Issues
A standard school vision test only checks distance sight, yet 75.5% of children with eye-teaming or tracking problems pass it undetected. Left unchecked, these hidden issues cause fatigue and behaviour that often mimics ADHD, delaying the treatment a proper eye exam would reveal.
From the Womb to the Playground: The Critical Early Years That Shape Your Child's Adult Vision and Brain Power
Placental inflammation and prenatal Vitamin D, tracked in cohorts of 1,000+ children, shape eyeball length and 10-year memory scores. Outdoor play from ages 4-7 offsets some risk, though not significantly.
Screens vs. Sunbeams: The Simple Outdoor Secret That Protects Your Child’s Eyes from Myopia
Childhood myopia is rising sharply, with US teen rates climbing from 24% to nearly 34% as eyeballs stretch out of shape during the school years. Screen time alone isn't the cause; two hours of daily outdoor light, which slows that stretching, is the simplest known protection.
The Invisible Shield: How Expectant Mothers Can Protect Their Baby’s Future Vision from Environmental Toxins
Prenatal arsenic exposure lengthens eyeballs and raises myopia risk, especially in boys, a study of 2,000 mother-child pairs found. Low maternal Vitamin D nearly doubles myopia odds by age nine.
"But My Child Sees Perfectly!" Why Kids Rarely Complain About Bad Vision and What to Actually Look For
Kids rarely mention blurry vision, assuming everyone sees that way. School screenings test distance only, missing up to 75.5% of coordination issues that mimic ADHD.
The Sunlight Secret: Why a Vitamin D Pill Won't Save Your Child's Eyesight, but the Playground Will

Can Plastic Particles Scar Your Eyes? The Invisible Immune Battle Happening on Your Cornea

Protecting Your Internal Shield: How Lifestyle Habits Shape Your Immune Age
The thymus, which trains immune cells, shrinks with age and is worsened by smoking, obesity and metabolic syndrome. A Harvard study of 25,000 adults found a healthy thymus linked to 50% lower mortality risk, with exercise and diet the main levers available now.
"What medication do you give them?" — German surgeons went looking for KSA's secret drug.
German surgeons kept asking what drug calms KSA's laser patients. It's actually nurse Ave Treier, 21 years in, whose calm voice and breathing routine ease fear before surgery starts.
Video Games to the Rescue? The Modern Ways to Treat a "Lazy Eye"
Amblyopia is a brain-eye coordination issue, not a muscle fault, often symptomless in young children. New dichoptic video-game therapies now train both eyes, working best before age seven.
