Blue light is a wavelength that falls in the visible light spectrum, with a range of 380-500 nanometers (nm). These wavelengths are very short and therefore produce a high amount of energy.   

Blue light is made out of two components: 

1. Blue-Turquoise Light - 450-500nm 
2. Blue-Violet Light - 380-440nm  

Blue-turquoise light is beneficial, natural light, which plays an important role in regulating our internal body clock — also known as the circadian rhythm — which comes naturally from the sun and helps control our sleep cycle. 

Blue-turquoise light has been shown to improve brain activity, improving memory, mood and mental performance. 

Therefore, you should not block out all blue light. It is important to expose ourselves to natural blue light to gain all of the perks mentioned above and to block the artificial blue light that is emitted by our digital devices. 

Blue-Violet Light 

Due to the short wavelengths and high energy it produces, blue-violet light scatters more easily than other visible light, which makes it more difficult for the eye to focus on and therefore has a greater chance to cause eye strain. This is the harmful blue light, which can be found in artificial lighting, such as digital devices.  

Overtime, exposure to this type of light has the potential to induce photochemical damage to the retina, increasing eye strain, dry eyes and reduced energy levels. 

Blue light glasses are designed to help reduce exposure to blue light emitted from screens. While they are not a medical device, many experts agree they can support visual comfort during screen use by reducing glare and helping ease digital eye strain symptoms like tired eyes and headaches.

They are best used as part of healthy screen habits, including regular breaks and limiting screen time where possible.

Children are spending more time on screens for learning and play. Extended screen use can contribute to digital eye strain, which may include:

• Tired or sore eyes
  
• Headaches
  
• Blurred vision
  
• Difficulty concentrating
  

Blue light exposure in the evening may also impact sleep patterns, as it can interfere with the body’s natural wind-down process.

Blue light can significantly disrupt the natural release of the hormone melatonin, which regulates our sleep-wake cycles, therefore impacting our circadian rhythms. This is extremely important for children and teenagers, whose circadian rhythms are shifting naturally. The blue light emitted by our digital devices sends signals to the brain that lead it to believe that it is still daytime, therefore causing us to be more awake later at night. This may result in sleep deprivation or low-quality deep sleep. Some side effects may include: 

• Lack of concentration when learning and working; 
• Adverse health effects; and 
• Impact on mental health and wellbeing. 

Dream Eyewear Australia products have a specific lens that enables sufficient protection from harmful blue light while also providing excellent clarity. The blue light coating on the lens filters up to 50% of the highest energy wavelengths associated with digital eye strain.
