BIONAUT™ was founded by opticians with more than 30 years of experience. We make our blue light glasses ourselves, right down to your own prescription. Not an off-the-shelf product from a box, but glasses of which we know every component.
It starts with the right light
Light is the most important time signal for your biological clock (your circadian rhythm). That is why we make two pairs of glasses, for two moments:
- SLEEP UV 550 filters 100% of blue and green light up to 550 nanometers. For the evening after sunset, with screens and artificial light.
- WORK UV 480 is a balanced filter up to 480 nanometers that preserves contrast and color. For daytime and the early evening, with screen work and office lighting. Permitted in traffic.
We deliberately do not sell transparent lenses with a filter up to ±420 nm. They filter only a small part of the blue spectrum and have no demonstrable effect on your sleep or biorhythm.
Lenses built up from layers
Good blue light glasses are more than a tinted lens. Our lenses consist of several layers, each with its own job:
- High-quality optical plastic lens (CR39) with the SLEEP UV 550 or WORK UV 480 filter, freeform ground for a pure image without distortion.
- Thermally hardened, so the layers stay firmly in place and the lens withstands daily use.
- Multi-layer super anti-reflective coating. Several ultra-thin layers that stop distracting reflections.
- Anti-static layer, so the lens attracts less dust.
- Hydrophobic, super-smooth top coat. Water and grease do not stick and your glasses are easy to clean.
Why anti-reflective coating matters
Without an anti-reflective coating, part of the light bounces back off the lens. You see lamps and screens reflected in your glasses, and your eyes have to work harder. With our multi-layer coating, more light actually passes through the lens. The result is a clear, calm image, even under artificial light and on a screen. Other people also see your eyes better, without reflections in your lenses.
Also with prescription, without compromise
Your own prescription and the right filter in one pair of glasses. We make lenses from +10 to -10, with cylinder and prism, single vision, multifocal or as screen glasses (computer reading glasses). Do you have a high prescription? Then choose extra thin lenses (index 1.6 or 1.67), so your glasses stay attractive and light. You can find the prices on our prices page.
Frames you will love to wear
You wear blue light glasses for hours each day, often in the evening or under artificial light. That is why we pay as much attention to the frame as to the lens: it has to sit comfortably, be kind to your skin and look good.
Hypoallergenic materials: acetate and titanium
We choose two materials that rarely cause irritation, even on sensitive skin:
- Acetate is made from natural, renewable raw materials such as wood pulp and cotton fibers. It has a deep gloss, is hypoallergenic and offers endless possibilities in color and shape. Read all about acetate.
- Titanium is light, strong and biocompatible, and does not rust or corrode. Our titanium frames weigh from just 9 grams, so you hardly feel them after a long day. Read all about titanium.
Beautiful frame colors
From classic black to warm tortoise and havana tones, from transparent grey and lemonade to toffee. Our titanium frames come in gold, silver, rose gold and black, among others. That way you find glasses that suit your style, and your skin and hair color.
Evergreen classics
No fleeting trends, but shapes that last for years: aviator, panto, rectangular, wayfarer, oval, round and cat-eye. You wear your glasses every day, so choose a shape you will still love in a few years.
An ergonomic fit
Glasses that fit well are glasses you actually wear. Our frames come in different sizes, with different lens and nose bridge widths, and we list the measurements for every frame. A light frame does not press on your nose and ears and can be worn all day. For children we have kids' frames, some with a spring hinge. Unsure about your size or shape? Read how to choose the right frame.
Riveted hinges
You can see quality in the details. In our frames the hinges are riveted, a sturdy connection built into the frame itself. Our logo is on the temples, a sign that these glasses were made and checked by us.
