What is blue light?
The sun is the main source of blue light (and also exposes us to UV light). Artificial light sources, such as digital screens and LED lights, also emit blue light.

The sun is the main source of blue light (and also exposes us to UV light). Artificial light sources, such as digital screens and LED lights, also emit blue light.
Engineered to filter out UV along with harmful blue light* from the sun and artificial light sources, while allowing beneficial light to pass through. Designed for protection during work-heavy days and exposure to sunrays.
Benefits of blue light glasses
You can wear blue light glasses pretty much all the time – they’ll protect your eyes from UV and harmful blue light* emitted from the sun and artificial light sources.
Prescription blue light glasses are great for dedicated periods of work, whether you're at your desk or on your feet. Filter out harmful blue light* while providing the vision correction you need.
The sun is the main source of our harmful blue light* exposure. If it's too dim to wear sunglasses, you can wear blue light glasses outdoors to protect your eyes from harmful blue light and UV rays.
Harmful blue light* can put your eyes at risk of retinal cell damage[1]. UV light can cause health issues, such as cataracts. Blue light glasses filter our harmful blue light and UV to support long-term eye health.
What to consider before getting blue light glasses
The blue light filtering technology of the lens sometimes creates a subtle blue reflection on the lens surface. It's not very noticeable, but others may see it when looking at you in certain lighting conditions.
May notice a slight yellow tint when lenses are placed against a white background. Can make colours appear warmer but won't greatly affect your vision, unless you require acute colour perception.
Our BlueReflect™ and BlueReflect Plus™ lenses are similar to clear lenses, but they have an additional benefit: to protect your eyes from UV and harmful blue light by filtering harmful light, both indoors and outdoors.
You may notice a very slight yellow tint in your BlueReflect™ lenses if placed against a white background — this is completely normal and comes from the embedded filter in the lenses. There will also be a slight blue reflection on the surface of the lens (which means the glasses are doing their job!).
BlueReflect Plus™ have an even stronger filter, and therefore a slightly more noticeable tint and blue reflection.
Our blue light filtering lenses can be worn pretty much any time you like, as they provide UV protection and harmful blue light filtration both indoors and outdoors.
However, you should wear sunglasses when outdoors in bright conditions to ensure visual comfort and optimum clarity. We also recommend using a secondary pair of clear lenses when driving at night and when your true colour perception can't be compromised, for the absolute best vision.
Yes – blue light filtering glasses help protect your eyes from harmful blue light* and UV. They help to reduce oxidative stress on retinal tissue, which helps to preserve retinal health over the long term.[1]
BlueReflect™ Standard filters out 90% of harmful blue light
BlueReflect Plus™ filters out 99.5% of harmful blue light
*Harmful blue light filtering measured at 410nm.
Blue light is sometimes called blue-violet light or violet light. It’s high-energy visible light in the wavelength of 400-500 nm (the light that humans can see), while ultraviolet (UV) light rays are higher-energy ‘invisible’ light in the shorter wavelength of 100-400nm that’s just beyond our perception.
Too much exposure to harmful blue light* can increase the risk of retinal cell damage.[1] Beneficial blue light helps us see better – it enhances clarity, contrast, and colour perception.
