ST Laserstrike HEV-Blue Sunglasses

ST Laserstrike HEV filters are manufactured using bespoke high quality optical grade thermoplastic, providing a combination of low weight and high impact strength. ST Laserstrike utilizes the latest lens manufacturing and coating technologies to produce the most advanced product available; providing efficient blocking of both HEV-Blue light and UV. The unique optical filtering reduces glare without the use of polarizers to ensure maximum clarity when viewing cock-pit instrumentation.

Long-term exposure to short-wavelength High Energy Visible light (HEV) and Ultra-Violet (UV) radiation causes increased risk to eye health in the form of cataracts and degeneration of the retina (Solar Maculopathy). Studies have found significant amounts of (HEV) known as ‘Blue-Light’ light enter the cockpit through the windscreen.

Between 2 and 10 times above the recommended safe level of HEV Blue light was found to enter the cockpit for a flight lasting 8 hours in an independent study.

ST Laserstrike HEV-Blue glasses reduce HEV levels by a factor of more than 20 times.
