Infrared-Seeing Contact Lenses Turn Humans into Night Visionaries

Researchers have developed contact lenses that enable humans and mice to see near-infrared light by converting it into visible wavelengths. These lenses use specialized nanoparticles embedded in standard soft contact material, allowing users to perceive flickering infrared signals without needing external power.

Eye Pressure May Trigger Irreversible Vision Loss

New research reveals how elevated eye pressure distorts blood vessels and disrupts oxygen delivery, potentially accelerating the progression of glaucoma, a leading cause of irreversible vision loss. Using advanced 3D modeling and fluorescent dyes, scientists found that even mild increases in eye pressure can restrict blood flow in the optic nerve region.

How Your Brain Splits Space to Double Its Perception Power

Despite popular myths about left- and right-brain thinking, research shows the hemispheres truly do divide up certain tasks—especially visual spatial perception. A new review reveals how each hemisphere processes the opposite side of your field of vision, not only early on but even in higher-level cognition like attention and memory.

Face Blindness Affects 1 in 50

A new study reveals that people with developmental prosopagnosia, or face blindness, struggle daily to recognize even close friends and family, despite having normal vision and memory. Many participants described coping strategies like keeping spreadsheets or using voices and clothing to identify others, but these are often exhausting and unreliable.

B Vitamins May Halt Glaucoma Progression

Glaucoma damages the optic nerve and is usually managed by reducing eye pressure, though treatment effects vary. Researchers have long suspected a link with homocysteine, but new findings reveal it is a bystander, not a driver of the disease.

Low Blood Sugar Triggers Retinal Damage, Vision Loss

New research reveals that hypoglycemia may worsen diabetic retinopathy by breaking down the blood-retinal barrier. In diabetic mice, low blood sugar increased levels of hypoxia-inducible factor (HIF), a protein linked to abnormal blood vessel growth and leakage.

How Visual Neurons Adapt in Real Time

New research reveals that neurons in the visual cortex are far more adaptable than previously thought, responding dynamically to complex stimuli during object recognition tasks. While visual processing has traditionally been viewed as mostly feedforward, this study shows that feedback from higher brain areas conveys prior knowledge and behavioral context to shape perception.

This shows two people looking at one another.

Eyes Reveal Intentions Faster Than We Think

Humans can detect another person’s intentions just by observing their eyes, even before any movement takes place. In experiments where participants watched video clips of people about to shift their gaze, viewers responded faster when the gaze was self-directed rather than instructed.

This shows a person surrounded by swirls.

Psychedelics Linked to Visual Echoes

As psychedelics gain traction in mental health treatment, questions remain about their long-term effects. A new study followed individuals self-administering psychedelics and found that while some experienced lingering visual aftereffects, most were not distressed by them.

Rewiring Retinal Messages to Slow Vision Loss in AMD

Age-related macular degeneration (AMD), the leading cause of adult blindness, affects nearly half of Oklahomans over age 80. New research is uncovering how retinal cells communicate using microRNA and extracellular vesicles (EVs), with the goal of slowing AMD progression.

Gold Nanoparticles Restore Vision in Macular Degeneration

A new study shows that gold nanoparticles injected into the retina can restore vision in mice with retinal degeneration, offering a less invasive alternative to current retinal prostheses. When activated by patterned infrared light, these nanoparticles stimulate retinal cells, bypassing damaged photoreceptors.

Eye Clues May Reveal Early Dementia Risk

A new study has found that blood vessels in the retina may hold early clues about a person’s risk of developing dementia. Researchers observed that narrower arterioles, wider venules, and thinner retinal nerve fiber layers were linked to higher dementia risk around midlife.
