The Science Behind ALTIUS® Performance Contact Lens

ALTIUS® 360 Degree Total Immersion Technology©

Patent Pending ALTIUS® Performance-Tinted Contact Lenses have been developed to eliminate visual distractions such as lighting glare while elevating critical visual details, such as visual clarity and contrast, to optimize performance. ALTIUS® Performance-Tints have been developed through years of clinical research and testing with elite athletes worldwide. See ALTIUS® research results and references here.

ALTIUS®, meaning “Higher” in Latin, are patent-pending Performance-Tinted Single-Use Contact Lenses created by Performance Vision Technologies, Inc., designed to mitigate visual noise allowing the athlete to perform with maximal Comfort, Clarity & Quickness under the extreme and varying visual and environmental conditions encountered in sports and recreational activities.

ALTIUS® 360 Degree Total Immersion Technology© utilizes “Light Architecture”© to selectively filter both the Quantity & Quality of light, resulting in a series of activity-specific tints blanketing the entire visual domain, thereby eliminating most environmental and optical problems inherent with sunglasses, such as peripheral light leakage, lens reflections, fogging, frame discomfort, water splash, lens scratches, lens cleaning, and optical/visual distortions.

Visible light includes all colors of the spectrum that we can see, going in order from violet to blue, green, yellow, orange, and finally, red. Those colors are shown across the top of the graphs.

Each individual color can be defined by its wavelength, usually measured in very small units of length called nanometers (nm). Visible light ranges in wavelength from about 380 nm (corresponding to the color violet) to about 780 nm (corresponding to the color red). These values are shown at the bottom of the graph. The peak sensitivity of the human eye in daylight is to a wavelength of about 555 nm, which will appear greenish-yellow in color.

Transmittance is the percentage of light of a particular wavelength that passes through a lens. Transmittance can range from 0%, in which the lens blocks all of that wavelength, to 100%, in which the lens allows through all of that wavelength. These values are shown on the left side of the spectral transmission graphs. The curve on the graph shows how the transmittance changes for each wavelength with ALTIUS® Amber and Grey-Green. For example, at the specific wavelength of 555nm, ALTIUS® Amber transmits about 40% of the light and ALTIUS® Grey-Green transmits about 50% of the light.

For the entire visible spectrum, ALTIUS® Amber has a total Visible Light Transmittance (VLT) of about 50% (the colored area on the right side of the graph, under the curve, covers about half of the size of the full graph). ALTIUS® Grey-Green has a total VLT of about 38% (the colored area on the right side of the graph, under the curve, covers a little more than one-third the size of the full graph).

ALTIUS® Amber and Grey-Green protect the eye by blocking harmful ultraviolet (UV) rays, which have wavelengths less than 380 nm (not shown on the graph).

ALTIUS® Amber and Grey-Green allows many of the colors of the spectrum to come through and be seen by the wearer, mostly in the green, yellow, orange, and red parts of the spectrum. But ALTIUS® Amber and Grey-Green block many of the visible wavelengths between 380 nm and 500 nm (the area on the left of the graph shown in gray), which corresponds to the violet and blue parts of the spectrum.

In the human eye, not all wavelengths focus at the same location. Short wavelengths (less than 555 nm) will have a shorter focus, while long wavelengths (greater than 555 nm) will have a longer focus. This is called “chromatic aberration” (C.A.). C.A. can cause images to appear blurred or reduced in contrast.

While blocking many of the wavelengths between 380 nm and 500 nm with ALTIUS® Amber and Grey-Green can cause some violet and blue objects to appear darker or even black, this has the benefits of simultaneously providing a comfortable perceived “Brightening Effect” of the environment, while reducing C.A. and, therefore, reducing what wearers perceive as “visual noise” in the environment. As a result, glare will be reduced, contrast will appear to be improved, and overall vision will appear sharper.
