Many of us spend hours each day in front of a digital screen. This has increased our exposure to the blue light that emanates from our devices, such as phones, laptops, and tablets. Blue light has been linked to eye strain and sleep problems which is why many people are now wearing blue light filter glasses. But are they effective? For many people, the answer is yes, although studies are still being carried out on how damaging blue light actually is. 

What Is Blue Light?

The human eye is susceptible to the visible light spectrum, which includes the blue light that emanates from the sun and the screens we use daily. While blue light is considered harmful, it does have its benefits. Scientists have concluded that blue light is helpful for boosting our cognitive functions and for regulating the sleep and wake cycles. 

However, there are negative side effects to blue light too. Researchers are still determining how damaging it can be but there have been suggestions that it could cause damage to the retina at the back of the eye. Blue light has also been associated with eye fatigue and other instance of eye discomfort. And as the blue light from our screens can affect our sleep-wake cycle, there is evidence to suggest that it can inhibit sleep if we use screens before bedtime. 

To counter the problem of blue light, blue light filter glasses (also known as blue lens glasses) have been created. While they are becoming increasingly popular, some consumers are asking if they really work. The answer is yes, blue light filter glasses do work, although how effective they depend on how much damage blue light does. If it is as damaging as some researchers suggest, then blue light filter glasses can be recommended.  

What Do Blue Light Filter Glasses Do?

Blue light filter glasses contain specially crafted lenses that reduce overexposure to blue light. The amount of blue light that is blocked can vary between glasses which is why you should speak to your optometrist before making a purchase. 

Blue light filter glasses generally have either clear or amber-tinted lenses. Clear lenses block between 20-40% of the blue light spectrum and this is enough for most people. Amber-tinted blue-light-blocking glasses can block much more than this and can be recommended for those who spend a lot of time looking at digital screens at night time. Both types of glasses can be recommended to those who are already experiencing digital eye strain and associated symptoms, such as headaches and dry and itchy eyes.

Should You Buy Blue Light Filter Glasses?

While the jury is still out on whether blue light can cause retinal damage, blue light filter glasses can still be recommended for those who need help to sleep better and who want to reduce eye discomfort. 

If you regularly use digital screens, especially of a night time, then you should certainly consider the option.
