Blue Light Lens Colour Guide - old
WHICH COLOUR BLUE LIGHT LENS DO I NEED?
When it comes to blue light glasses, there are so many different colour lenses to choose from. Knowing exactly what each lens colour type does and what applications they are designed for is essential when selecting a pair of blue light glasses. Also, knowing what exact specifications to look for in each of these different colours is paramount to ensure what you're buying is going to actually work and be effective.
BlockBlueLight has extensively researched and developed a wide range of different lens colours that have been optimised to be the most effective for different applications and situations. Unlike most other blue light glasses available, we have developed superior lens technology by infusing our lenses with proprietary light filtering pigments that are produced in an optical lab to ensure superior clarity and blue blocking properties.
The list below gives you a full detailed overview of which colour you need and the specifications of each colour to look for when choosing your blue light glasses.
Clear Lenses

Daytime Clear lenses are part of our ScreenTime Computer Glasses range. These blue light filter glasses are designed to be used during the daytime when a person is exposed to artificial blue light coming from computer screens, phones, tablets, LED, and fluorescent lighting. Our unique ClearBlue lens technology provides crystal clear vision with minimal colour distortion. The transparency of the clear lens allows the beneficial blue light through, which is responsible for alertness, motivation, and positive mood, whilst filtering down the damaging blue light wavelengths that cause headaches, migraines, digital eye strain, and even eye damage, such as macular degeneration.
The ScreenTime Blue Light Computer Glasses filter blue light by 50% across the entire blue light spectrum (400nm-500nm). More specifically, they filter blue light by 50% at 455nm. This is an extremely important feature you should ensure is included in your computer glasses, as the peak wavelength of blue light being emitted by digital devices is 455nm. In other words, for computer glasses to be effective, they need to be filtering this exact wavelength of blue light.
Sadly, not all computer glasses are created equal; most clear lens computer glasses on the market only mainly filter violet light and a small amount blue light up to 430nm. This means they aren't providing any blue light protection where it's needed the most. Make sure you opt for a brand whose computer glasses provide a full breakdown of the specification of their lenses to ensure they filter blue light across the entire blue light spectrum and focus on filtering 50% of blue light at 455nm.

Daytime Yellow lenses are part of our DayMax Blue Light Glasses range. These glasses provide maximum protection against blue light during the daytime and can often be described as light sensitivity glasses. The DayMax yellow lens block 100% of the lower part of the blue light spectrum which is responsible for light sensitivity issues such as anxiety, depression, migraines, eye strain, and dry eyes.
The DayMax light yellow lenses are ideal for people who are light sensitive, regularly suffer from migraines and eye strain, or are prone to anxiety, depression or low mood. These symptoms indicate the need more protection against blue light than our ScreenTime computer glasses are able to provide. If you also work in an office with large amounts of LED and Fluorescent lighting, or with no natural light, then DayMax Glasses are for you.
The light yellow DayMax lenses use propriety filtering technology to specifically target and to block 100% of blue light in the lower range of 400 - 455 nanometers; this is the most energetic and damaging light emitted from screens and lighting. More importantly they still allow all the beneficial blue light through still which is in the later part of the blue light spectrum from 455-500nm, this is the blue light that is essential during the day for optimal hormone production, energy, positive mood, and motivation.

Night-time Amber Lenses make up our SunDown Blue Blocking Glasses Range. These amber blue light glasses block 100% of blue light. The SunDown Blue Light Blocking Glasses are designed for evening use to increase melatonin levels and sleep quality. The amber lens is an ideal option for people still wanting a high quality premium 100% blue blocking lens, but prefer a lighter amber tint over the red lens to allow more colour perception in the evening hours.
Once the sun sets in the evening, we typically turn on LED lights in our home, watch TV, and look at phones and computer screens, and all of these are very high sources of blue light. Any amount of exposure to blue light in the evening sends a strong signal to our brain that it's still daytime. The brain responds to this by suppressing our sleep hormone, melatonin, and increasing the production of our stress hormone, cortisol. This keeps us feeling awake and alert when we are supposed to be winding down and feeling relaxed. The biggest symptoms of blue light exposure at night are difficulties falling asleep and staying asleep. This is why it’s extremely important to block 100% of blue light at night to ensure you are getting deep and restful sleep.
Not all amber blue blocking glasses are the same. When looking to buy a set of blue light glasses for night-time, ensure the company can provide a lens testing report showing and verifying 100% of blue light is being blocked by their glasses, as even a small amount of blue light after sunset will send these daytime signals to your brain, which will significantly lower sleep quality.
The Amber Lenses are offered in the following different models:
- Our SunDown Stylish models are made with a high-quality acetate frame with spring hinges in the arms. These are a good option for when you are going out and socialising or someone wanting something a more stylish & fashionable.
- The SunDown Amber Lens is also available in our very cost effective Original and FitOver Original range of blue light glasses. The Original range is great for someone on a budget who still wants a quality pair of blue blocking glasses that block all blue light and have the same lens technology as many of the other more expensive brands.

Night-time red lens are used in our NightFall Blue Blocking Glasses range. These red lenses block 100% of blue light and 100% of green light up to 550nm. This makes them hands down the most powerful and effective blue and green light blocking lenses available.
So why block green light? Isn’t blocking blue light enough? Well, academic studies show it’s not just blue light that’s the problem; green is right next to blue in the colour spectrum, and the science clearly shows the melatonin disruption range also extends into the green light spectrum up to 550nm. This means blocking both blue and green light has a more powerful effect and ensures your getting the maximum benefits from mitigating artificial light.
Sure, if you wear one of our SunDown Amber glasses you'll dramatically improve your melatonin levels and sleep quality, but the Nightfall Red glasses boosts the effect even further. If you're serious about your sleep, performance, and health, these are the glasses for you.
The NightFall Red Lenses are offered in the following different models:
- Our NightFall Premium model is designed with a full wrap-around fit with a full coverage foam barrier border. This eliminates any "light leakage" and light still getting in from the sides and top of the glasses.
- Our NightFall Stylish models are made with a high-quality acetate frame with spring hinges in the arms. They are stylish enough to wear out in public but designed with optimal function to ensure maximum protection—the best of both worlds!
- Our NightFall Kids Glasses are made for children between 3-10 years old and feature the same blue and green light filtering technology.
- Lastly, we have our NightFall FitOver Glasses, which allow you to combine them with prescription or reading glasses and still get maximum protection.
