Guide to Healthy Lighting - Why UV and Flicker Matter

What is healthy lighting and why is it crucial to your wellbeing?

Summary:Healthy lighting is lighting that is completely safe for users and does not cause discomfort. Key features of such lighting are the complete elimination of invisible, harmful UV radiation and the absence of unnoticeable flicker (flicker effect). This combination protects the eyes and skin, and significantly improves concentration and overall wellbeing in rooms where we spend a lot of time.

An invisible hazard: How does UV radiation in lighting affect health?

Ultraviolet radiation (UV) is the invisible part of the light spectrum that is harmful in excess. Although it is mainly associated with the sun, some traditional light sources, such as fluorescent lamps and older types of lamps, can emit it in small amounts. Prolonged daily exposure indoors can accumulate negative effects. EV Sun lamps are designed tocompletely eliminate UV emissionswhich makes them completely safe for any application.

What are the effects of long-term UV exposure from artificial light sources?

Area of Influence	Potential risk
Sight	It can contribute to retinal damage and accelerate eye ageing.
Leather	It can negatively affect the condition of the skin by accelerating photo-ageing.
Environment	It causes fading and colour degradation of furniture, fabrics and also works of art.

What is flickering light (flicker) and how it affects the brain and eyes

Light flicker (flicker) is a very fast, cyclical change in light intensity, often so fast that it is invisible to the naked eye. Nevertheless, the human brain and nervous system register them. This forces our pupils and visual receptors to perform constant, microscopic adaptive work. This unconscious effort leads to a number of negative health effects.

What are the symptoms of fatigue caused by fibrillation?

TechnologyBlue Care, present in all EV Sun lamps (except fluorescent lamps), guarantees100% flicker-free. This provides a perfectly stable light output that eliminates the following problems and creates optimal conditions for working and relaxing.

Symptom	Description
Headaches and migraines	Tension caused by the pupils' constant adaptation to changes in light.
Eye fatigue and burning	Increased effort of the eye muscles trying to maintain a constant focus.
Decrease in productivity	Concentration problems due to the distracting effect.
General irritability	Subconscious, constant strain on the nervous system.
