Blue Light Glasses
Blue light glasses have gained popularity over recent years due to the increasing usage of digital devices. Both adults and children spend more hours a day looking at monitors and smartphones. So, what are blue light blocking glasses and why are they beneficial?
What are blue light glasses?
Blue light blocking glasses have been specially designed with lenses to filter out and block the unwanted blue light given off from digital screens. Wearing blue light glasses can help reduce the effects of exposure to blue light. Blue light has the shortest wavelengths and highest frequencies. Therefore, the light gets scattered into other directions causing haze and blur on screens, making it difficult to focus. This can lead to digital eye strain and fatigue.
Do I need blue light filter glasses?
You might need blue light filter glasses if you are overly exposed to digital blue light. The primary source of blue light is emitted from the sun and by artificial sources such as digital screens and modern lighting. It’s the blue light from digital devices that can impact our eyes. So, if you spend a lot of time in front of your phone, tablet or computer screen, blue light glasses might be the answer to reduce eye strain and optimise your visual comfort.
Here are a few signs that you might need blue light glasses:
- You have headaches
- You have eye strain
- You have eye-fatigue
- You have trouble sleeping
- You spend hours in front of digital devices
Can you get prescription glasses with blue light filter?
Yes, you can get blue light blocking lenses for your prescription glasses. During the manufacturing process of your lenses, a special coating will be applied to block the blue light. All our frames at Feel Good Contacts can be customised with blue light blocking lenses. Our blue light blocking lenses are scratch-resistant with a special multi-layered glare coating applied. This will help reduce unwanted reflections and provide clear vision.
What are the benefits of blue light glasses?
These glasses are designed to block some of the blue light that emits from digital devices such as your mobile phone, tablet or laptop. Limiting this blue light in the evenings might help with easing digital eye strain and give you better quality sleep.
Wearing blue light glasses may reduce the effects of:
- Dry eyes
- Digital eye strain
- Sleep cycle disruption
- Macular degeneration
Do blue light glasses help with eye strain?
Yes, blue light glasses help minimise the digital eye strain put on by looking at screens all day.
Blue light reduces our production of melatonin (sleep hormone) which help us sleep at night. Inevitably, this causes us to stay awake longer at night and excessively stare at our screens. This will not only disrupt our sleep cycle but also lead to eye strain. For this reason, you will find blue light lenses help with both sleep and digital eye strain.
Can you wear blue light glasses all day?
You can wear them all day if you want to, blue light glasses are safe to wear. There’s a common misconception that the lenses cannot be worn all the time. However, this is not correct. Glasses wearers can get blue light lenses with their corrective prescription and wear all the time to help them see. We recommend taking regular breaks from digital devices if you spend most of your day in front of screens.

Can blue light glasses help me sleep better?
Yes, these glasses can help your sleep better by filtering blue light which can omit from your digital screens. In the evenings when we are exposed to the blue light from electronic devices, that light tricks our brains into thinking it’s daytime, and we should still be awake. By reducing our exposure to blue light in the evenings, our bodies can more easily feel sleepy and ready for bed.
Is blue light bad for you?
There is some benefit to having blue light exposure during the day, as it helps keep the brain alert. However, there is also some (but not definite) evidence to suggest that too much exposure to harmful blue light can cause long term damage such as macular degeneration and dry eyes. Other conditions/consequences can also include migraines, sore eyes and disrupted sleep. Protect your eyes with a pair of glasses that filters out the blue light.
Are gaming glasses the same as blue light glasses?
Although gaming glasses perform the same function as blue light glasses or computer glasses, they often have flatter/straight arms, so that they can comfortably sit against the head when worn with headphones. Oakley glasses are a great example of glasses that are well suited in design for gaming.
