Yes. Our acetate frames are plant-derived and we don't use any animal products in our lenses, cases, or packaging.

All glasses are available in one-size only. Check the individual product page for size options and measurements.

Each style page includes the frame dimensions and a fit guide. If you're unsure, email us before ordering and we'll point you in the right direction.

Use the included microfibre cloth and lens spray. Avoid paper towels, clothing fabric, or any dry cloth that hasn't been designed for lenses — these scratch the coating over time. Don't leave glasses in a hot car or direct sun for extended periods.

Every pair comes with a hard protective case and a microfibre cleaning cloth.

All sunglasses and blue light lenses provide UV400 protection, blocking 99–100% of UVA and UVB radiation.

Our casual range uses cellulose acetate — a plant-based, hypoallergenic material that holds its shape well and can be polished to a high finish. Metal frames are constructed from an alloy called Monel. Our sport frames use TR-90, a flexible, lightweight thermoplastic that can bend without breaking and holds securely under physical exertion.

Our lenses are made from CR-39 optical resin or polycarbonate, depending on the range. Blue light lenses use a multi-layer coating or tinted resin that absorbs specific wavelengths. Polarised lenses (casual and sport) use a TAC polarising film bonded within the lens to eliminate horizontal glare. All lenses are scratch-resistant coated.

Yes. Whether you're at a screen, outdoors, or winding down for sleep, there's a pair built for that moment. Many customers wear multiple pairs across the day depending on what they're doing.

Most eyewear is designed around aesthetics. everambr is designed around how light affects your body — your focus, your sleep, your recovery. Each range is built for a role in your day, not a look on a shelf.

Blue light is a high-energy visible (HEV) wavelength emitted by the sun, LED lighting, and digital screens. Your body uses it as a biological cue — particularly in the morning, it signals alertness and suppresses melatonin. The problem is that we're exposed to high levels of it from screens throughout the day, including in the evening hours when the body should be winding down.

Prolonged exposure can contribute to digital eye strain — symptoms include tired eyes, headaches, and difficulty focusing after extended screen time. Evening exposure is more disruptive: blue light in the hours before sleep delays melatonin production, making it harder to fall asleep and reducing sleep quality. everambr lenses are designed to manage that exposure at different points in the day.

The three lens tints filter different amounts of blue light. Clear lenses filter approximately 20–30% of blue light — close to transparent with a very slight tint, suitable for general screen use during the day when you want protection without any noticeable colour shift. Yellow lenses filter approximately 50–65% of blue light — the amber tint is visible but light, suited to heavy screen time, late afternoon work, and situations where you want stronger filtering without cutting off all blue light completely. Red lenses filter 95%+ of blue light in the wavelengths that affect melatonin — designed for the 1–2 hours before sleep.

Clear: everyday screen use, daytime hours, if you want protection that doesn't change how colours look on screen. Yellow: extended screen sessions, productivity work, late afternoon or early evening use. Red: evening wind-down, 60–90 minutes before bed. Many customers own two pairs — yellow for the workday and red for evenings.

Many customers report reduced eye strain and fewer screen-related headaches, particularly with the yellow lens during extended work sessions. Results vary depending on your screen habits, lighting conditions, and how much blue light exposure you were getting before. They work alongside good screen habits — the 20-20-20 rule (every 20 minutes, look at something 20 feet away for 20 seconds) remains useful regardless.

Clear lenses produce minimal colour shift. Yellow lenses warm your screen noticeably — most people adjust within a day. Red lenses produce a strong amber shift, which is intentional; they're not designed for colour-sensitive work.

Yes. Clear and yellow lenses are comfortable for all-day wear. Red lenses are designed for pre-sleep use only — wearing them during daylight hours will affect your perception of colour and brightness more than intended.

Yes. Even at 20–30% filtration, clear lenses reduce cumulative exposure meaningfully over an 8-hour workday. They're not the strongest option, but they're designed for people who need protection without any visible tint on their screen.

The deep red lenses block the blue and green wavelengths of light (roughly 480–550nm) that suppress melatonin production. Wearing them in the evening creates the optical equivalent of dimming the biological triggers for wakefulness, allowing your body to begin its sleep preparation on schedule even if you're still in a lit room or using a screen.

60 to 90 minutes is the recommended window. The earlier you put them on, the more time your body has to build up melatonin before you actually try to sleep.

Yes. The lenses block the harmful wavelengths while allowing enough visible light through that you can continue normal activities. Colours will look distinctly amber-toned, but screens are still fully viewable.

Some people notice improvements in how quickly they fall asleep within a few nights. Others take 1–2 weeks of consistent use to see a change. The most consistent results come from wearing them at the same time each evening rather than on an occasional basis.

The sleep glasses range is purpose-built for pre-sleep use, with lens geometry and frame design optimised for comfort when lying on a sofa or reading in bed. The red-lens blue light filter level is similar, but the form factor differs.

The frames are designed with a wraparound fit and grip-optimised nose pads and temple tips that keep the glasses in position during movement. There's no frame flex under standard running or training conditions. They're designed to stay where you put them without needing to push them back up mid-activity.

No. Polarised lenses are better suited to casual and driving use. For sport, non-polarised lenses give you better contrast and clarity across changing light conditions, and avoid the visual anomalies that polarised lenses can produce when looking at LCD screens or certain reflective surfaces (like a bike computer or running watch).

Running, cycling, hiking, and outdoor training. They're not designed for water sports or activities that require impact-rated lenses.

The frames are water-resistant and the nose and temple grip materials maintain traction when wet. They're not waterproof and shouldn't be submerged.

UV400 — full UVA and UVB protection.

Acetate is a plant-derived material made from cellulose fibres. It's heavier than plastic but holds its shape better over time, takes colour and pattern more richly, and sits more comfortably on the face. It's the standard material in higher-quality frames because of its durability and finish. It can also be adjusted slightly by an optician using heat if the fit needs tweaking.

Yes. Polarised lenses reduce glare from reflective surfaces — water, roads, glass — making them easier on the eyes in bright outdoor conditions. Colours appear more saturated and contrast improves.

UV400 — full UVA and UVB protection.

Yes. The acetate frame and polarised lens combination is suited for daily outdoor wear — commuting, driving, weekend use. They're not built for high-intensity sport.

At checkout, you'll be prompted to enter your prescription details manually or upload a photo of your prescription document. You'll need your sphere (SPH), cylinder (CYL), and axis values for each eye. If you have a prism correction, note that in the comments field and we'll confirm whether we can accommodate it.

We accommodate prescriptions from -8.00 to +6.00 sphere, with cylinder up to -4.00. If your prescription falls outside these ranges, contact us before ordering and we'll advise whether we can accommodate it through our lab partners.
