The Brain's Nightly Deep Clean: How Deep Sleep and Microscopic "Gardeners" Shield You Against Alzheimer’s Disease
Deep sleep lets microglia prune synapses by nearly a fifth nightly and clear toxic proteins. Chronic sleep loss turns these cells destructive, leaving amyloid damage visible in retinal scans.

Precision at the Speed of Light: How the Laser Technology Behind Flow3 Works
The Flow3 laser fires 1,050 pulses a second yet treats each eye in under 30 seconds. Five engineering systems keep the flapless procedure fast-healing and glare-free.

The Cancer Mimic in Your Orbit: The Retina's Warburg Effect
The healthy retina mimics tumours, using the Warburg effect to fuel constant renewal of light-sensing cells. Its breakdown is linked to AMD and diabetic retinopathy.

The Invisible Editor: Why Your Brain Works Overtime to Make Your Glasses Feel "Normal"
Lenses subtly warp the world, forcing the brain to rewire its vestibulo-ocular reflex until distortion feels normal. That hidden correction drains energy, leaving eyes and temples tired by evening.

The Digital Clog: How Screens and Blue Light Stall the Daily Cleanup of Eye and Brain
Blue light and late snacking jam the eye and brain's nightly cleanup systems. Screen curfews and the 20-20-20 rule can restore them, keeping vision and cognition sharp.

The Metabolic Shield: How Ketogenic Pathways Support and Protect the Retinal Ecosystem
Retinal support cells clear daily debris from rods and cones, guided by the sensor mTOR. Fasting or ketogenic diets switch mTOR to clean-up mode, freeing glucose for photoreceptors.

Why the Future is Completely Cut-Free: How Flow3 Protects Your Eyes' Biomechanical Strength
Traditional LASIK cuts a corneal flap, weakening the eye and severing tear-regulating nerves. Flow3 reshapes the surface without cutting, preserving strength for active lifestyles.

The Path of Central Vision: How the Fovea Was Shaped by History and Biology
Early mammals lost sharp foveal vision after going nocturnal, but primates later rebuilt it for daylight. The pit shape forms from mechanical stretching of the embryonic eye, not cell loss.

The Midnight Engine: Why the Visual System Operates with Constant Activity in the Dark
Photoreceptors stay active in darkness, holding ion channels open and burning oxygen and glucose. This dark current, fed by the choroid, lets retinal exams reveal circulation problems elsewhere.

Glasses, Contacts, or Laser Eye Surgery: The Quest for Natural Vision
Glasses resize the world by lens distance, but contacts and laser close that gap entirely. Flow, a touch-free procedure, removes both that distortion and the oxygen restriction contacts cause.

Why Do New Glasses Make You Dizzy at First?
New lenses bend light differently at the eye's edges, briefly tricking the brain into seeing walls and doorways shift. A Berkeley and Meta study found a 2-4% image size shift alone caused dizziness.

When the Neural Cleanup Crew Strikes: The Hidden Cellular Failures Driving Vision Loss and Cognitive Decline
Vision loss can stem from failing retinal cleanup systems, causing macular degeneration and retinitis pigmentosa. Exercise and intermittent fasting may reboot these processes at the gene level.
