G-15 Lens Technology: How Does It Work?

How Does G-15 Work?

Green and yellow light are in the center of the light spectrum at 555 nanometers and are most easily perceived by the human eye. G-15 lenses maximize the transmission of these colors, decreasing the strain of focusing and creating a cooling sensation for the eyes. These lenses broadcast colors the same way the human eye receives them, resulting in true-to-life vision and less eyestrain. No other lens technology can boast these unique scientific properties.

G-15 Lens Technology: History

A Preventative Solution: G-15 Lenses

The history of G-15 technology dates back to the 1930s when newer airplanes allowed pilots to fly higher and farther than ever before. Many U.S. Army Air Service Pilots were reporting that the glare from the sun was giving them headaches and altitude sickness during flight. In 1929, U.S. Army Air Corps Lieutenant General John MacCready asked Bausch & Lomb, a New York-based medical equipment manufacturer, to create aviation lenses that would reduce the headaches and nausea caused by the intense blue and white hues of the sky. A new kind of lens was introduced in 1936: known as G-15 Anti-Glare, they featured green lenses that cut out the glare without obscuring vision.

G-15 Lens Technology: Eyestrain

The Problem? Eye Strain

According to the Mayo Clinic, Asthenopia (eye strain) is a debilitating ophthalmological condition. When concentrating on a visually intense task for long periods of time, the ciliary muscle tightens, causing pain that manifests itself through non-specific symptoms such as sore or irritated eyes, headaches, difficulty focusing, dry or watery eyes, blurred or double vision, increased sensitivity to light, and pain in the neck, shoulders, or back.

These symptoms not only cause one to be terribly uncomfortable, but can also decrease productivity. The pain may also be intensified by lack of sleep, a time when the eyes are replenished with essential nutrients. While getting more sleep and taking regular breaks can be helpful, there is a preventative measure that can stop eye strain before it starts.

Hamel

The Hamel has a modern wrap-around design that flawlessly combines function and fashion. This stylish eye pro looks great with BDUs or casual attire, while its ballistic rating makes it a perfect choice for the most unpredictable circumstances. Its flexible and durable rubberized matte black frame has foam nose pads that make the glasses easy to wear all day. A sleek brow guard blocks light from above and recessed lens cavities prevent airflow from drying out the eyes. The standard frame style is available with Polarized Gradient, G-15, enhancing Tiger’s Eye, or Clear lenses.

The Hamel frame looks great with Crye Precision’s MultiCam finish. This pattern is used worldwide and was designed specifically for hiding in various environments. The frame is available with Polarized Gradient Smoke and G-15 lenses.

Thin temples provide pinch-free comfort and functionality when worn with a helmet or ear protection and keep a sealed fit with noise reduction headsets.

Sharp Edge

The blade-style Sharp Edge is a lightweight pair of range glasses that are ideal for any tactical activity. The flexible and durable matte black frame is equipped with soft thermoplastic rubber temple arms and adjustable nose pads to create a comfortable, nonslip fit. The absence of a lower frame prevents sight obstruction, making it great for shooting.
