Can you wear blue light glasses all day?

The biggest trend in eye health and wellness in the past few years has to be blue light glasses. Especially for people who spend a lot of time in front of screens, whether for work or leisure. But can you wear them all day as regular glasses?

But first, let us try and understand what these glasses do. 

The bane of blue

Blue light is the high energy, short wavelength part of the visible spectrum of light. They make a cloudless sky look blue! The sun is the biggest source of these rays, and like UV rays, they have both benefits and harmful effects. Other sources of these rays include digital devices like smartphones, laptops, tablets, TV, etc. Their close proximity to our eyes and overexposure is a cause of concern for some experts.

Our eyes are not very good at blocking these rays, which can penetrate the front portions to reach our retina. While studies are still going on, there can be a risk that it leads to a lot of problems like macular degeneration and cataracts, apart from digital eye strain, headache, lack of sleep etc. Blue light has amazing benefits as well – it helps to boost alertness and memory. It also helps in regulating our circadian rhythm, the natural sleeping and waking up cycle. You must be wondering how!

When our eyes are exposed to blue light, it signals our brain that it is daytime. That is why it is not advised to use screens late into the night, since it can mislead our body into thinking that it is daytime and disrupting our sleep schedule.

Blue light glasses

Blue light glasses are a great piece of functional accessory. A lot of people think that getting glasses with anti-reflective coating and anti-UV sunglasses will help do the trick. But blue light is something else entirely, and you may need separate protection for it. But how does it work?

These glasses have a special coating that blocks or absorbs most of the blue light from reaching your eyes. Since they block only these harmful rays, they don’t impede your vision in any way. If you wear Transitions (leading type of photochromic lenses that develop a dark tint when you step out into the sun), you might not need separate blue light coating.

3 signs you need them

You spend most of the day looking at a digital screen – If you spend more than 9 hours in a day in front of a screen, you might need blue light glasses. It could be for work, study, playing games, watching a movie, etc. In this day and age, most professions and colleges involve working on laptops, phones and tablets. Even kids spend a lot of time on digital devices.

Your eyes feel strained or tired – If you have been feeling eye strain, blurred vision, headache, watery eyes or similar problems, it might be time to get a pair of blue light eyeglasses. Do consult an eye care professional in such a case.

But since exposure to blue light can have a direct effect on our sleep schedule, it might be wise to invest in a pair of blue light glasses. As mentioned before, it can disrupt your sleep cycle by suppressing melatonin (the hormone that regulates sleep wake cycle) and affecting Rapid Eye Movement sleep. Even if you buy cheap prescription glasses online, make sure that they’ve an anti-blue light coating.
