Lenses allowing for safe and comfortable work in front of computer screens. We can distinguish here lenses supporting accommodation, i.e. relaxation lenses and lenses with a special coating that reduces the amount of blue light reaching the eyes.
Excess blue light has a negative impact not only on our eyes (burning, redness or blurring of the image), but also on our entire body - the excess of blue light emitted inhibits the secretion of melatonin, a hormone responsible for our daily rhythm (e.g. sleeping and waking). The negative effect of working in front of the computer for too long without proper eye protection is insomnia. Lenses with a filter limiting the amount of blue light reaching our eyes are recommended not only for people with visual impairments, but also for people who do not need to wear glasses, but work all day in front of monitors.
