All lenses we use is optical mid-index what means it is more slim (thinner) than regular ones. In our lenses highest possible visual clarity and optical quality is prioritized. All lenses are made especially to to work with screens and and contains 100% UV light protection and blue-light protection filters. Both filters block high energy light and protects from eye tissue damage.

Our frames are made from high quality acetate. Frames are selected to provide both comfort and style. Manufacturers are selected based on our knowledge and long-term expierence. Each detail of the frame is high-end and shows great quality and durability.

It is important to understand you need blue light glasses with or without optical power. There are 3 main factors which determine the necessity for optical power: 1. distance vision quality (undisturbed or disturbed), 2. age (until or over 40), 3. working distance (classic reading or screen on arm length). Keep in mind that our production is made especially for screen users, so we have created optical power guide according to age and working distance (if distance vision is undisturbed).

Naturally blue light comes from sunlight, but most digital screens (phones, tablets, TV’s, computers) emit blue light, too. Blue light exposure from screens is a lot smaller than from sunlight. And nowadays we spend around 8 hours/ per day with different type of screens. Our eye structures naturally absorb the blue light, it means that retina have to be protected. It is done by crystalline lens which is 1 of 2 main optical structures in human eye (cornea is another one). We have to keep in mind that filtering increases with age- younger eyes have very clear crystalline lens (blue light reaches the retina), but in adults or older age lens becomes more yellow (more blue light is blocked). With this prolonged screen time we often can feel digital eye strain what usually contains contains dry eyes, headaches and blurry vision. We have to understand that this is mainly due to different factors- reduced blinking, glare and prolonged focus.

High energy visible light (HEV) contents blue and violet light. Wavelength range is from 380 to 480nm, where relative energy (from visible spectrum by human eye) is the highest. The main effects of HEV light are: 1. Digital eye strain. 2. Eye fatigue. 3. Dry eyes. 4. Headaches. 5. Glare sensitivity or reduced contrast. Prolonged periods of HEV (high energy visible light) exposure often cause eye strain. The HEV light with shorter wavelengths contents high relative energy. HEV light scatters more easily and image on screens appears lower in contrast. It forces the eyes to focus harder what often result as eye strain and even headaches.

Blue light suppresses melatonin secretion. Melatonin is the hormone which controls your sleep-wake cycle (circadian rhythm). It rises at night and falls in the morning. Too much blue light ,especially on the evening or night, significantly disrupt your body’s circadian rhythm, what means difficulties to fall asleep or stay asleep.

1. Screen setup. Keep screens at arm’s length distance and slightly below eye level. 2. Lightning optimization. Match screen brightness to your room lightning (don’t use screens in comletely dark room). No window behind you = no direct daylight reach the screen. 3. 20-20-20 rule. Every 20 minutes look at something 20 feet away for at least 20 seconds. It helps to relax eye’s natural “zoom”. 4. Blink more. When using screens blinking drops signifficantly (around 50%). 5. Sleep enough. Around 8 hour sleep helps to protect against dry eyes and irritation. 6. Optical factors. Use the right prescription! Use the blue-light glasses when working with screens, especially in the evening.
