Lens Technology


Lens Technology is crucial in protecting your eyes. Light reflecting off the water causes glare which can be especially harmful to the eye and reduces your visual acuity. Polarized lenses reduce this glare on a horizontal surface. A good pair of Polarized sunglasses will eliminate glare and help keep your eyes safe from environmental hazards, harmful UV and infrared radiation.

  • Elimination of nuisance and discomfort caused by glare.
  • Amazing visibility and clarity, especially in very intense and bright environments.
  • Enabling the wearer to see beneath the glare like fish in the water.

Visual Clarity

Prevents visual fatigue thanks to low haze and high material transparency

In daylight, the human eye is exposed to:

  • short wavelength ultraviolet radiation (UV)
  • visible radiation or visible colors
  • long wavelength infrared radiation (IR)

Infrared radiation (IR) lies beyond the red end of the visible spectrum, with wavelengths between 780-10.000nm. Infrared can’t be seen but can be felt as heat. High intensity IR can lead to damages to the ocular tissues, dryness and discomfort of the eyes.

Most infrared radiations are absorbed by the ocular structure, raising the overall temperature of the eye.

Hook Optics Sunglasses with ThermoForce Lenses by Zeiss are the ultimate pair of sunglasses. They are light weight, made for extreme weather conditions, protect your eyes by blocking out UV and IR rays, prevent fatigue, while providing High Definition Clarity.

  • Easier to Clean than Most

When working or playing in extreme heat and environments for a prolonged time like many fishermen do, it is suggested to take all precautions to keep the eye safe and cool. The Lens Technology in Hook Optics ThermoForce lenses by ZEISS can help you do that. They better protect your eyes while preventing visual fatigue, providing a more comfortable day on the water.

This lens allows for a 92% reduction of Infrared radiation compared to a standard polycarbonate sun lens.

  • Thermo Force absorbs up to 90% near (A) and far (B) infrared radiation (from 780-2000 nm), coming from natural sources.
  • This results in a cooling effect for the eyes, the eyelids and the face areas
    shielded by the lens.
  • It also offers full UV protection (400 nm).
  • Extremely clear and much lighter than mineral glass.

Hook Optics Lenses by ZEISS Block Both UV and Infrared Light

The sun’s radiation is a continuous spectrum made up of electromagnetic waves with higher or lower energy. Visible light, also known as visible spectrum, is the portion visible to human eye, allowing it to distinguish shapes and colors. The eyes are also exposed to two other kinds of energy: ultraviolet light (UV) and the infrared (IR) rays. Up to 53% of sunlight is made of infrared radiation which cannot be seen by the human eye but is perceived as heat.

Hook Optics ThermoForce lenses block both UV and IR rays, keeping your eyes cooler providing you more comfort throughout your day.
