We were only able to find a single problem with this particular screen protector. Unfortunately, it does have a lot of glare.

If you were to sit in an area where a light could reflect off it, then you would be able to see your own reflection. This could be a problem for some people who cannot move their monitor, but a lot of people would just make sure that they are angled away from the light.

These Blue Light Blocking Computer Glasses can be used by people who wear contact lenses, but they should not be worn by people who should be wearing prescription glasses.

Unfortunately, you cannot have your own prescription applied to these glasses, but there are some alternatives that will let you. We would advise that you speak to your optician if you do have to wear prescription glasses about what they can offer you.

4. Lighting Science Sleep Promoting LED Light

Lighting Science is a company who specialize in producing products that will enable you to have a perfect sleep. They manufacture a range of different bulbs, some of which have been designed specifically for nurseries.

If you are looking for a bulb that will help you sleep, then we would recommend that you try a few before settling with one. You might find that one works better for you than another.

Product Highlights

This Lighting Science Sleep Promoting LED Light is something that could help everyone get a good sleep, even people who usually struggle to sleep. Sleep bulbs like this one work by emitting less blue light than other bulbs do, this enables you to settle down and sleep when you need to.

One of the main problems with blue light and sleep is that our circadian rhythm is quite literally controlled by blue light. We are awake when the sun is up, then we sleep when it goes down. The lack of blue light when the sun goes down leads to our brains producing the hormone melatonin, a natural sleep aid.

Unfortunately, in the modern world blue light is still being emitted by all of our electronics, preventing our brains from producing as much melatonin as they otherwise would.

Lighting Science FG-02263 Goodnight Sleep Bulb
  • Good Night Biological LED sleep light that helps to improve sleep
  • This sleep aid light supports your body's natural melatonin production (a hormone necessary for a good night sleep)

  • Helps to promote a healthy circadian rhythm to sleep naturally by assisting you in falling asleep faster and staying asleep longer
  • Specifications: 8.5 watts energy used; 22.8 years of average life; 600 lumens of brightness

What's to like about the Lighting Science Sleep Promoting LED Light

This bulb works because of science and human biology. By stopping yourself from being exposed to the sort of blue light that is usually emitted by bulbs, you can make sure that your brain starts producing melatonin early enough at night. That melatonin will help you get a peaceful and relaxing sleep. It will also help you to get to sleep quicker than you usually do.

Lighting Science have also made sure that you will not be exposed to any unnecessary blue light. This bulb is capable of eliminating up to 95% of the blue light portion of the electromagnetic spectrum. You simply have to make sure that you have this bulb in the room that you would usually spend the last portion of your day awake in.

What's not to like about the Lighting Science Sleep Promoting LED Light

While the Lighting Science Sleep Promoting LED Light is capable of enabling you to get a better sleep, it does not factor in a few other things. For example, if you were to have this bulb in one room and then walk into another brightly lit room, then that would be enough to completely negate any of the positive effects that you could have experienced.

You also have to consider the fact that there are other items that emit blue light. For example, your mobile phone, your television and any other digital devices that you might have lying around your house.

PROS

  • check
    Helps the body produce melatonin
  • check
    Enables you to sleep better
  • check

BLUE LIGHT FILTER BUYER'S GUIDE

When it comes to products that can be used to protect your eyes from blue light, you have to know the ins and outs of what you are purchasing. You have to know how the product works, why it works and whether or not it will work well. Our buyer?s guide will discuss everything that you need to know.

Blue Light Filter Types

There are different blue light filters that you can purchase. There are physical screen protectors that can be attached to monitors or stuck onto the screens of phones, glasses that are able to block out blue light and devices that have been developed to simply emit less blue light in the first place.

Most of these products work by using warm tints. For example, most blue light filtering glasses have orange or yellow lenses. Orange lenses are better at filtering out blue light, but yellow lenses provide the user with slightly less color distortion.

Blocking Blue Light Capacity

The amount of blue light that can be successfully blocked out depends entirely on the individual product. Some blue light blocking products can block up to 65% of blue light, whereas others can block a staggering 98% of blue light from ever reaching your eyes. Make sure that you look closely at any information that the manufacturer has given you.

Compatible Model

Some blue light filters can only be used with certain models of certain devices. For example, you would not be able to use an iPhone 8 screen protector on a Motorola phone, or vice versa.

You have to make sure that the screen protector that you are purchasing is compatible for use with your digital device and that you won?t end up with a screen protector that is so large that it hangs off each side.

Blue Light Filter RGB Levelling

RGB means red, green and blue and it is a system that represents all of the colors that can be used on a computer display. When we take a look at blue light filters, we have to understand that they are literally trying to remove one of the electromagnetic waves that make up our visible color spectrum, meaning that the amount of blue is dramatically reduced.

Blue Light Screen Filter Color

The color of each individual blue light screen filter can vary dramatically. Some of them are clear, some are yellow, some are orange, and some are red. A lot of clear products are made for their practicality opposed to their functionality. For example, you would be more likely to wear a clear pair of glasses than you would be to wear a red pair.

Each color works slightly differently from the next. A yellow filter would enable you to see a lot of the natural colors underneath the filter, but it would not remove a lot of blue light. Whereas, an orange filter would stop you from seeing a lot of the natural colors underneath, but it would stop a huge amount of blue light from reaching your eyes.


BLUE LIGHT FILTERS FAQ

Do blue light filters work?

Yes. Blue light filters work in protecting your eyes from any blue light that is being emitted by a digital source. Some blue light filters leave your screen looking as though it has an orange tint while also blocking the blue light from traveling through it. Some clear blue light filters are available, but they are not as effective.

What does low blue light do?

Low blue light is something that everyone should think about. By removing a large chunk of the blue light that we are exposed to on a daily basis, we can make sure that our eyes remain healthy. Prolonged exposure to blue light can cause a lot of different problems, including eye strain, fatigue, a lack of motivation, degenerative eye conditions and even an inability to sleep.

What is the blue light filter on an Android?

The blue light filter on an Android device is usually referred to as ?night mode.? Night mode is important because it reduces the amount of blue light that is emitted by your Android smartphone. It is also important to understand why it is called night mode.

Blue light quite literally keeps us awake and stops us from producing a lot of melatonin, our sleep hormone; this disrupts our sleep and can make it incredibly difficult to get to sleep.

How do you filter blue light on a laptop?

The best way to filter blue light on a laptop would be to use a unique screen protector. Screen protectors that have been designed for blocking blue light usually clip onto the top of the screen and they are usually made out of acrylic.

This acrylic usually has special coatings on it, one of which ensures that it can stop any blue light that is being emitted by the laptop from reaching your eyes.

Does blue light filter save battery life?

Using a blue light filter on an Android smartphone or an Apple smartphone should not noticeably affect your battery life at all. It will reduce the brightness of the blue LEDs within your phone, but that shouldn?t affect your power enough to be noticeable.

It is also worth considering the fact that your phone battery will reduce as you are using your phone, something that is highly likely if you are remembering to turn on night mode.

Do orange glasses block blue light?

Glasses that have orange-tinted lenses are fully capable of blocking blue light from reaching your eyes and they perform much better than both yellow-tinted lenses and clear lenses do.

Blue light is emitted from a range of different devices, including monitors, tablets and phones so wearing a pair of glasses can be a rather simple solution when you compare it to having to put screen protectors on every one of your devices.

How do you test blue light filters?

Blue light filters are incredibly important because of the protective benefits that they can offer us. But, how do you know if your blue light filter actually works? There are a few retailers out there who would happily sell you a product that doesn?t.

There are bars of electromagnetic spectra that you can use online to make sure that your blue light filter is working perfectly, and we would advise that you check any blue light filtering product.
