Blue light

The lenses are characterised by their tint, which ranges from a barely noticeable pale yellow through orange to a deep red.

All of us can use Blue Block lenses in our everyday lives. Blue light is increasingly appearing in our surroundings, whether it be conventional lighting in offices and homes, modern TV screens, smartphones, or the growing number of xenon or LED car lights. Blue light affects your sleep rhythm by suppressing the secretion of the “sleep” neurohormone melatonin and disrupting the natural circadian cycle. In addition, it carries a significant proportion of the light energy that enters your eyes, putting a strain on the retina and thus fatiguing your eyes. Lenses with a Blue Block finish are suitable for wearers who:

• Work long hours in front of computer screens every day.

• Use blue light sources, such as smartphones, tablets, LED TVs.

• Drive at night.

• Require higher contrast in the wavelength outside the blue component, such as shooters, athletes, cyclists, skiers.

• Suffer from age-related macular degeneration (AMD).

• Are albinos or very light pigmented types.
