Blue light glasses can truly be for anybody. You don’t have to fall within a certain group of people to wear them, nor will blue light blocking glasses have a negative effect on you if you don’t consume much screen time.
If you’re still wondering do I need blue light glasses?, there are a few ways to determine if you would really benefit from a pair. Mainly, if you fall under one of more of these categories:
They spend a lot of time looking at a screen
Many people’s jobs require them to spend a lot of time in front of a computer screen — we’re talking 8 hours per day, 5 days per week. It’s also common for those people to scroll through their phones or watch TV when they’re not on the clock, adding more hours to their screen time.
While this may not seem like a big deal, excessive screen time can wreak havoc on your eyes. Wearing a pair of blue light glasses can lessen the amount of strain your eyes feel when gazing at a computer, phone, or television screen.
They have trouble falling or staying asleep
If you find yourself wide awake after scrolling through your phone in bed at night, there’s a reason why. Blue light emitted from screens lowers melatonin levels, the chemical in your brain that helps you sleep.
Exposure to blue light can throw people’s internal clock out of whack, leaving them feeling more alert when they’re supposed to be winding down. Wearing a pair of blue light glasses, even if just in the evenings, can help regulate your melatonin levels and restore your good night’s rest.
They experience symptoms of digital eye strain
You don’t have to sit in front of a screen all day or have trouble sleeping in order to be affected by blue light. Everybody is different. Some can sit in front of a screen for hours on end with no effects and others can only handle an hour or two of screen time before they begin to experience symptoms of digital eye strain.
Also called computer vision syndrome, this reaction to prolonged, uninterrupted screen exposure can present itself in a variety of ways at varying intensities. Symptoms of digital eye strain include:
- Blurred vision
- Dry eyes
- Sore, red or tired eyes
- Stiff neck and shoulders
While blue light glasses won’t solve every symptom of digital eye strain, it can significantly reduce the amount of stress put on your eyes.
Do I need a prescription for blue light glasses?
It’s natural for people to associate glasses with vision correction, so they often ask, do I need a prescription for blue light glasses?
Rest assured, fine-visioned friends; a prescription is not needed for a pair of blue light glasses. This makes blue light protection possible for those who don’t require eyesight correction, or for those who prefer to wear contacts, but want a layer of blue light defense.
If you do require a prescription, don’t worry — we’ve got you covered also.
Blue light blockers have a lightly-tinted coating on top of the lenses that filter the amount of blue light allowed into your eye. The coating accommodates any strength of prescription lens, shielding the eyes of whoever needs it.
Benefits of blue light glasses
The benefits of blue light glasses depend on how much blue light (ie. screen time) you consume.
For instance, if you only consume a few hours of blue light per day, you likely won’t experience any drastic benefits from blue light lenses. However, if the blue light you consume is near bedtime and affects your sleep, blue light glasses can help balance your circadian rhythm.
Another benefit offered by blue light glasses is less glare projected from bright screens. This results in less eye strain, fewer headaches and unbothered eyes.
Will blue light glasses prevent digital eye strain?
As mentioned earlier, everyone’s sensitivity level to blue light is different. Blue light glasses are meant to reduce the symptoms of digital eye strain, not completely eliminate it.
If you find blue light glasses aren’t doing the trick for you, it could be because you’re staring at a screen, without a break, for several hours at a time. Along with wearing blue light lenses, we recommend taking frequent breaks from your screen, where you focus on a distant object or close your eyes and allow them to rest for a moment.
It’s also possible that your eyes are straining because your vision prescription is out of date and needs to be renewed. If your prescription is incorrect, no amount of blue light filter will prevent eye strain.
So, what’s our verdict? There’s no harm in trying blue light lenses. They provide benefits and relief to many individuals who swear by them.
What’s more, the cost to add blue light blockers to our lenses starts at $19, so you don’t have to break the bank to give them a try. Check out our selection of blue light blocking glasses to get started on your blue light journey today.
