With custom engineered lenses manufactured on machinery from the ophthalmic industry and eyewear features found only on best in class frames, Penta delivers professional grade comfort along with the industrys best optics. Adjustable nose pads allow for a customisable fit. Rigid steel lens mounts precisely hold the lenses without creating stress that can degrade the optical experience. Soft silicone temples grip lightly to keep the eyewear in place. Ultra strong and flexible stainless steel ensures long term durability along with optimal comfort.
Gunnars are high performance prescription compatible computer eyewear optimised for the digital screen. Comprised of a proprietary lens material in an advanced geometry tuned for specific viewing distances and finished with custom formulated lens filters, tints and coatings so Gunnars indoor eyewear delivers an immediate and noticeable advantage when viewing any digital LCD screen.
Designed to enhance contrast and visual performance whilst minimising screen glare and reflective light plus selectively neutralising the harsher parts of the colour spectrum, Gunnars computer eyewear technology is the result of intense study and research on the human optical system and its interaction with digital technology.
Essentially, the benefits of Gunnar high performance eyewear include reduced visual stress, augmented details and an environmental barrier blocking ambient air currents to alleviate dry eye effects.
iONik lens tints:
With advanced spectropotometry, Gunnars lab technicians have the ability to study and analyse even the most difficult lighting environments. Each part of the visible and invisible light spectrum can be measured and quantified. To balance and optimise that lighting environment for the needs of the human eye, the Gunnar lab techs then use a combination of iONik lens tints and i-FI coatings.
fRACTYL lens geometry:
Designed using advanced computer algorithms, fRACTYL lens geometry mimics nature by focussing light. The highly wrapped configuration creates an ocular microclimate trapping in humidity and blocking out evaporative air currents.
i-FI lens coatings:
i-FI multi-stage lens coatings filter transmitted light and protect the lens. The anti-reflective portion cuts glare and distracting extraneous light. A hydrophobic component keeps water spots to a minimum while an oleophobic coating protects from smudging and fingerprints. A final hard coat reduces environmental wear and minimises scratching.
