Lenses with a blue-light filter
Computer glasses
Hours at the monitor, then the laptop and in the evening the phone. All day your eyes look at one distance, blink less than they should and receive a lot of light from screens. No wonder that by evening they burn, feel dry, the image blurs and sometimes a headache follows. At IMOOPTIK we have three proven solutions for you: Rodenstock Solitaire Balance coating and XiRON Optics XTREME CLEAN BLUE and XTREME CLEAN UV420 lenses. We make XiRON lenses while you wait at most of our opticians.

Three solutions for screen-tired eyes
Rodenstock Solitaire Balance
A premium coating that Rodenstock recommends for glasses for screen work. It reduces artificial blue light from monitors and phones to a natural level by reflecting it from the front surface of the lens, while colour perception remains natural. According to Rodenstock this helps maintain a balanced biorhythm and restful sleep. The reflex is slightly blue.
- Solitaire 2 technology: twice as scratch-resistant as a standard anti-reflective coating
- UV protection on the front and back of the lens, anti-static, repels water and dirt
- 36-month Rodenstock quality warranty on Solitaire Protect coatings
- also available as Solitaire LayR Balance X-tra Clean: up to 50 % fewer reflections and 70 % longer life than the previous generation
- in stock at the supplier or custom-made, delivery within 48 hours
XiRON XTREME CLEAN BLUE
Our premium anti-reflective coating with a blue-light filter. On the front of the lens it reflects about a fifth of blue light, precisely in the band where monitors, LED lights and phone displays shine most. Your eyes are calmer at the screen and the lens stays clear.
- the back has low reflection, so light from behind you is not reflected into your eyes
- hardened, anti-static, resistant to fingerprints and grease, easy to clean
- the reflex is slightly blue
- ideal for the office, home office and in the evening for your phone or TV
XiRON XTREME CLEAN UV420
Here protection is not just on the surface but in the lens material itself. UV420 material absorbs all UV radiation and blue-violet light up to 420 nm, from every direction. On the surface is our premium XTREME CLEAN coating with a green reflex, so the lens looks completely natural.
- protects at the screen and outdoors in the sun
- no blue reflex – nobody will notice you have a filter
- lets through blue-turquoise light, which we need for a good daily rhythm
- in indices 1.5 · 1.6 · 1.67 · 1.74, ideal for all-day wear
two ways to let less blue light into the eye
How it actually works
Rodenstock Solitaire Balance and XTREME CLEAN BLUE both work on the lens surface. Thin layers reflect part of the blue light from the screen before it reaches the eye – that is why the lens has a slightly blue reflex. Rodenstock describes this as reducing artificial blue light to a natural level to preserve the natural biorhythm and sleep, while colour perception does not change. XTREME CLEAN UV420 takes a different route: the protective substance is dissolved throughout the lens material, so the lens simply absorbs UV radiation and blue-violet light up to 420 nm, whichever side it comes from. A neutral coating with a green reflex is then enough on the surface. All three lenses are hardened, don’t attract dust, and water or grease wipe off easily.
blue for screens, green for all day
Blue or green reflex? It depends on where you wear your glasses
The colour of the reflex says nothing about the quality of the anti-reflective coating. It does, however, reveal what the lens is tuned for. A blue reflex (XTREME CLEAN BLUE, Rodenstock Balance) reflects exactly the band of blue light emitted by monitors and LED lighting, so it suits the office, home office or the phone in the evening. Outdoors the situation is different. The main source of blue light is the sun, many times stronger than any screen. The reflective layer then creates a strong blue sheen on the lens, visible to people and cameras, and does little for the eyes. A green reflex with UV420 lenses (XTREME CLEAN UV420) works differently: blue-violet light is absorbed by the whole lens, so it protects at the screen and in the sun, looks neutral and doesn’t change colours. Put simply: if you spend most of the day at a screen, choose XTREME CLEAN BLUE or Rodenstock Balance. If you wear glasses all day, indoors and out, choose XTREME CLEAN UV420. And if you want both at once, we will gladly prepare UV420 material with the BLUE coating to order.
protection on the surface or throughout the lens
What is the difference between UV420 and a lens with just a blue coating
An ordinary lens with a blue coating protects with a thin surface layer. It reflects part of the light hitting it from the front but has no effect on light from the side; its effect depends on the condition of the surface and the blue reflex is visible on the lens. A UV420 lens has protection throughout the material. It absorbs 100 % of UV radiation and blue-violet light up to 420 nm regardless of where it comes from, has no blue reflex and its effect does not change over time. That is why we recommend UV420 as the basis for anyone who wears glasses all day, and the blue coating for those who spend most of their working time at a screen.
blue coating vs. UV420 lens with XTREME CLEAN coating
Comparison in brief
Blue coating: protection in a thin surface layer, reflects part of the blue light from the front, has a visible blue reflex and is best indoors at screens. UV420 lens: protection throughout the material, absorbs UV and blue-violet light up to 420 nm from every direction, has a subtle green neutral reflex, its effect doesn’t change over time and it suits all day indoors and out. And if you want the best of both, we will prepare UV420 material with the XTREME CLEAN BLUE coating to order.

four small things that help your eyes as much as the right lenses
Tips for computer work
Place your monitor about an arm’s length away with its top edge slightly below eye level. Every 20 minutes look into the distance for at least 20 seconds – this simple 20-20-20 rule greatly relieves your eyes. Don’t forget to blink: according to Rodenstock, during focused work we blink up to 40 % less and our eyes dry out. In the evening dim your displays and switch on night mode – your eyes rest and you fall asleep more easily. If your eyes still burn or you get headaches, come to us for an eye examination. Often a small correction or the right computer lenses are enough.
