Is it bad to wear blue light glasses? Though blue light glasses aren't effective at preventing digital eye strain, there is no harm in wearing them. “It is not harmful to wear them all day,” says Dr. Bajic.
Cons of Blue Light Glasses
The blue cut lenses alter the colour of everything you see in the yellow hue. Another blue cut lenses disadvantage is that they are unable to protect skin that also contains melanopsin, a photoreceptor that tells your body whether it is day or night.
Cheap blue light glasses do not filter the complete range of harmful wavelengths. Research has proven that the peak wavelength from artificial light is at 455 nanometres. None of the cheap pairs target this wavelength.
The fact is, the coatings do not block blue light from the entire blue light spectrum or the part of the spectrum the matters the most. Many blue light filter glasses claim to block a large percentage of blue light. However, the range of blue light they filter matters greatly.
Yes, it is okay to wear blue light glasses all day. Whether you're wearing blue blocking glasses without a prescription or a special blue filter on your regular glasses, your eyes will not suffer any negative effects from wearing them all the time.
As The College of Optometrists states: 'The best scientific evidence currently available does not support the use of blue-blocking spectacle lenses in the general population to improve visual performance, alleviate the symptoms of eye fatigue or visual discomfort, improve sleep quality or conserve macula health. '
Look at a Spectrum Report
Most companies that sell blue light glasses will have a spectrum report on hand that shows how much blue light the glasses actually filter. This is the only way to know for sure whether or not your glasses are actually blue light blocking glasses.
Most of the pairs have UV protection and adjustable nose pads and, for some pairs, you can get the lens replaced with a prescription from a different provider if necessary. With price tags between $68 and $835, you can find a pair that works for your budget.
Blue Light Glasses keep the eyes relaxed and help improve your sleep cycle. Anti-Glare, on the other hand, makes the eye comfy and the eyesight clear. Blue Light Glasses are advised for individuals who operate with LED light sources, while Anti-Glare Glasses are indicated for those who drive late at night.
Blue Light Filters
You don't have to worry about the filter changing the display or color because these protectors do not heavily distort the viewing experience.
No. Blue light blocking glasses don't damage your eyes. In fact, blue light glasses shield your eyes from the damaging effects of blue light, which is the type of light that's emitted from electronic devices, like tablets, smartphones and laptops.
The simple answer is no; not all blue light glasses are created equal. According to Vision Monday, eyeglasses that filter the “dangerous levels” of blue light (400-500 nanometers) are the glasses that actually protect your eyes.
It is as easy as it sounds. Just wait for a clear day and hold your glasses towards the blue sky. During normal wear, the lenses look clear, but they actually have a slight yellow tint if filtering the recommended 30% of blue light.
Some people have reported headaches from blue-light blocking glasses, but there haven't been any reliable studies to support or explain these reports. It is not uncommon to have headaches when you first wear new glasses or your prescription has changed.
Constant exposure to blue light over time could damage retinal cells and cause vision problems such as age-related macular degeneration. It can also contribute to cataracts, eye cancer and growths on the clear covering over the white part of the eye.
Yellow tinted glasses are designed to filter out a higher level of blue light that is emitted from your screen. Yellow lenses are often recommended for gamers and are also a good option for anyone using a screen throughout the evening.
Blue light fools the brain into thinking it's daytime. When that happens, the body stops releasing a sleep hormone called melatonin. Melatonin is nature's way of helping us wind down and prepare for bed. The body starts releasing it a couple of hours before bedtime.
There is no credible scientific evidence to show that blue light damages the eyes or can cause other health issues. There is also no evidence that blue light glasses help reduce symptoms associated with increased exposure to screens.
Blue light blocking lenses should be worn anytime you are using a screen or device that emits blue light. Keep your eyes healthy and reduce digital eye strain with a great pair of blue light blocking lenses.
The simple answer is no; not all blue light glasses are created equal. According to Vision Monday, eyeglasses that filter the “dangerous levels” of blue light (400-500 nanometers) are the glasses that actually protect your eyes.
The percentage amount of blue light blocked is the first thing to take note of. Aim for a pair blocking over 95% of blue light. Also, consider the lens color, if they are FDA approved, have UV rated anti-glare coating, the sturdiness of the hinges and if prescription lenses are available.

Final Takeaway! To summarise, transparent blue light filter glasses reflect less blue light and do not alter color perception. They are perfect for wearing during the day since they allow you to get natural blue light.
