SIGHT PERFORMANCE
A fractured visual signal
A prominent blue spike scatters within the eye, creating internal glare. A deep void in the red wavelengths delivers an incomplete signal, forcing the brain to guess at missing information.
The ultimate human drug
The scientific evidence that shows how the right light can transform your wellbeing.
How light impacts your sight
Peer-reviewed evidence proving the direct link between spectral quality, eyestrain, and the clarity of the words on a page.
Blue light scatters in the eye, creating glare.
Research confirmed short-wavelength light scatters within the eye, creating an internal veiling glare that reduces contrast and visual clarity.
Read full studyThe colour of light directly impacts visual discomfort.
Researchers proved glare isn't just about brightness; the specific colour spectrum of light is a key factor in visual comfort and eyestrain.
Read full studyImbalanced light spectra can cause visual fatigue.
A controlled trial found that light with a warmer, more balanced spectrum significantly improved visual comfort during sustained tasks.

Peer-reviewed evidence on how the light spectrum acts as a primary signal to regulate your natural sleep-wake cycle.
Humans have a blue-sensitive melatonin “off switch.”
Landmark research identified the precise blue wavelengths that suppress the sleep hormone melatonin, proving a non-visual pathway governs our internal clock.

A clinical study showed even typical indoor light before bed is powerful enough to delay and shorten melatonin release, disrupting a full biological night.
Read full studyEvening light spectrum directly impacts sleep quality.
Blue-enriched evening light was shown to disrupt deep sleep by reducing the restorative slow-wave brain activity critical for recovery.

Light modulates alertness, attention and reaction time during the day.
Daylight-like office light boosts alertness and performance.
A real-world office study found daylight-mimicking light significantly boosted alertness, concentration, and performance while reducing sleepiness.
Read full studyBlue light gives your brain an immediate alertness jolt.
Monochromatic blue light was shown to produce greater alerting effects and stronger melatonin suppression than green light, improving vigilance.
Read full studyThe spectrum of light activates cognitive brain networks.
Brain imaging (fMRI) revealed blue light activates key brain regions for memory and focus, directly linking light spectrum to cognitive function.
Read full studyA clinical perspective
The science of eyestrain is not an abstract concept. For independent opticians on the front line of vision health, it is the daily reality their patients describe. They see the direct, clinical link between a flawed spectrum and the struggle to see clearly.
Only your verdict matters
We can show you the science. You can hear from the experts. We can wax lyrical about how better light will transform your view. But, in the end you need to try one yourself and make up your own mind.
