Blue Light Blockers

An evening lens, in deep red.

The last hour before bed shouldn't look like the middle of the day. A deep red lens, bonded through the material, filters the harsh end of the spectrum out of every screen in the room.

Blocks 99% of blue light, 400 to 500 nm. Wear from sundown.

Why the lens is red, not yellow

Tint depth is the whole product.

A clear or faintly yellow lens takes out a slice of the blue range. It is built for daytime screen glare. A deep red lens takes out effectively the entire range, which is why it looks the way it looks. There is no way to remove blue light and keep the lens clear. The colour is the evidence.

Simple test: if you can still see blue on the screen through the lens, the lens is not blocking blue. More on that in why blue light glasses are red.

When to wear them

From sundown, indoors, whenever a screen or an overhead light is on.

Not a daytime lens. Not a driving lens. A deep red tint changes how you see colour and how much light reaches you, so these are for the couch and the desk after dark, not the car. Longer answer: when to wear blue light glasses.

Questions people ask

Are these the same as normal blue light glasses?

No. Most blue light glasses sold in Australia are clear or faintly yellow and are made for daytime computer use. These are a deep red evening lens. Different tint, different time of day, different job. See the full red, amber and yellow comparison.

Why do things look red?

Because the blue and most of the green wavelengths are not getting through. Your eyes adjust within a few minutes and the effect stops being noticeable.

Can I wear them over prescription glasses?

No. These are a standalone frame, not a fit-over or a clip-on. If you wear glasses full time, you would need to swap.

Can I use a screen filter or night mode instead?

Night mode shifts the colour of one screen. It does nothing about the lamp above your head, the TV across the room, or the bathroom light. A lens covers everything you look at.

Do they work in the daytime?

They are not made for it. Daytime blue light is mostly sunlight, and a deep red lens is the wrong tool for a lit room in the middle of the day.

Do blue light glasses actually do anything?

Fair question, and we wrote an honest answer rather than a marketing one: what the evidence actually says, including what the 2023 Cochrane review tested and what it did not.

What is the return policy?

30 days, money back. If the fit is wrong or they are not for you, send them back.
