Here we demonstrate the different colors and the wavelengths attributed to each one of them. Now, the longer the wavelength, the less health effects you’re actually gonna see on your eye. So red, green, above 550, you’re not gonna see as many health effects. Violet light, may have heard of a UV light. That’s when it starts getting dangerous, and blue light is right on that same hinge. But we also, wanna show you how the human eye works, so you can understand how you even see these different colors.

Right here, you have the human eye. There’s the optic nerve, cornea, pupil, lens, retina. Right here, when the light comes in, it goes through the eye, goes right here to the retina and then hits. These photo receptors are what allow you to see color. And there’s four types of these photo receptors. Three of them being cones. One of them being rods. The cones are red, green, and blue, and they allow you to see color in the daytime. Rods allow you to see at night without any color.

Let’s talk blue light and your health. The most evidence we have in the way that blue light affects your health is through our biological clock. Also known as our circadian rhythm. Blue light actually suppresses melatonin. That’s a hormone released in our brains to make us sleepy, to help us fall asleep at night, and stay asleep during the night. Now, if you’re exposing yourself to a lot of blue light at night, immediately before going to sleep, that can make you less sleepy. As you can imagine, that’s problematic.

All different types of light can actually suppress your melatonin hormone. That’s why in all my sleep videos, I recommend keeping it as dim as possible before bedtime. But that being said, Harvard actually studied it and compared blue light to green light, and they found blue light suppressed melatonin almost twice as much as green light, and shifted your circadian rhythm twice as much as compared to green light three hours to one and a half hours.

Now, that’s not all bad news. When you wake up in the morning. The first thing I tell you guys is to open up your shades. The reason is, the sunshine that has a lot of blue light in it, will actually suppress that melatonin hormone, making you less sleepy, more alert and resetting your circadian rhythm, so you can fall asleep easier for the following night. This actually brings up an interesting dilemma because as we’re moving to become more energy efficient, we’re using more LED lamps, more fluorescent lights, as opposed to the traditional incandescent light bulbs. And while that’s great for the environment, that may come at a personal health cost.

So how do we balance this moving forward? I think in the future, we’re gonna have lamps that release blue light, but perhaps the coverings of the lamps can actually filter some of that blue light out. Unless we have a major innovation in the next five to 10 years, which can also be a possibility.

Let’s talk about a couple of health conditions for your eyes where blue light is not necessarily the culprit.

Starting off with eyestrain. Digital eye strain, also known as computer vision syndrome. This happens when we’re staring at a computer, TV, cell phone screen. When you do that for a long period of time, people tend to develop this eye strain, this eye fatigue. The real reason this occurs, is from that intense focus that happens, leading to muscle fatigue around your eye. And also because when you’re that focused, you’re not blinking as much, and not blinking as much leads to more dryness, which leads to irritation, burning, stinging. And guess what? I have a few tips for you on how to battle that eyestrain.

1. You want to be at least two feet awayfrom your computer screen.
2. If you’re gonna bestaring at a computer screenfor a really long period of time, think about using eye lubricating drops.
3. This one is my all time favorite, 20/20/20 rule. Every 20 minutes, you want to stare at a point that’s 20 feet away for at least 20 seconds. This wall out your eyes to relax, the muscles to recover, and for your focus to regain. This is the most important step in preventing or treating digital eye strain.

Macular Degeneration. This is the center portion of your retina. And if you lose your macula, if you have degeneration, you actually lose the central part of your vision. There’s been some evidence linking UV and blue light exposure to the acceleration of age related macular degeneration. But here’s what we actually found. It takes an enormous amount of blue light to actually do damage to this part of your retina. So if you stare at the sun where there’s a tremendous amount of blue light, absolutely you can cause yourself some damage. But when we look at research and we see the amounts that you’re getting from your screens, it’s a lot less and probably not enough to the degree to cause significant damage. In fact, when you compare blue light exposure from electronics to aging, smoking, being overweight, cardiovascular disease, high blood pressure, the electronics are just a minimal risk and not something you should spend a lot of time thinking or worrying about.

So how do we protect ourselves from blue light affecting our ability to fall asleep and altering our biological clocks? My recommendations actually fall in line with Harvard Public School of Health.

• First, get rid of the screens at least two hours before bedtime, maybe even three hours if you can.
• Two, use dim lights before bedtime, ideally red dim lights. Red lights are less likely to shift your circadian rhythm and affect your sleep.
• Three, consider blue light blocking glasses if you have late shifts or have work to do at night. Glasses I’m wearing right now are actually filtering out blue light. And I wear them when I watch videos late at night on the computer. I’m a big fan of all the different styles that Jim Halo has.

Sunglasses and fashion are inseparable. Once you put on sunglasses, you would feel a kind of difference in seconds.

1. UV protection

Dark-colored sunglasses do not mean that they are UV protective, while light or colorless does not mean that they cannot anti UV rays.

If you are also wearing optical glasses, it usually has a UV protection function. It should be said that most of the optical lenses currently on the market have UV protection, and the sun protection index is not low.

The UV protective ability of the lens mainly depends on the UV value.

If the lens marks anti UV400, it means that it can block 99% of ultraviolet rays below 400nm, including UVA, UVB, and UVC.

2. Polarized lens

Some sunglasses use polarized lenses. What does this mean? Look at the picture below.

The bright and dazzling reflected light on the water surface in the picture is polarized light. If you are outdoors on a sunny day, there will be such diffusely reflected polarized light everywhere, which will stimulate our eyes and make us unable to see the real scenery.

What happens if we wear polarized lens sunglasses?

When wearing polarized lenses, you can find that your eyesight has improved and you can see more clearly.

Whether it is day or night, polarized lenses can filter out some strong reflected light, allowing you to see more clearly.

3. Color

The color of sunglasses has nothing to do with UV protective ability, but it relates to how much light is weakened, and the visual effects.

1) The gray lens can effectively reduce the intensity of the light without changing the color of the object. Visible light in bright sunlight is also harmful to the eyes, so weakening the light is a way to protect our eyes.

2) The brown lens can block some blue light, but the color of the object may seem to change a little. It is suitable for the occasions like snow, water, beaches, etc.

3) Yellow/amber blocks most of the blue light, but the color of the object may change significantly. This color lens is suitable for viewing mobile phones, computers, etc. (effectively filter blue light)

4. The bigger, the better

If you want to achieve the best UV protection effect, in addition to the sun protection index of the lens, there is a secret： The bigger the better.

OK, do you get your own ideas of choosing sunglasses now?

2. Round Shape Face

If you have a small chin, narrow forehead, and full cheeks, then you have a round face.

Apart from this suggestion, it’s better to choose dark color sunglasses for round shape face. Because bright colors will make your face look bigger. Those thick frames and angular sunglasses would be good choices for you. Our suggestion to improve your look is to choose a square shape or cat-eye sunglasses.

3. Oval Shape Face

If you have a long face and have cheekbones a little bit wider than your forehead, then you have an oval shape face. You can choose classic square sunglasses for a daily look. And you can also choose wraparound or oversized sunglasses to focus more on your chin and forehead.

4. Heart Shape Face

If you have a narrow chin but a broad forehead and wide cheekbones, then you have a heart shape face. So you’d better choose frames that do not look too small for the top half of the face. And avoid wearing oversized sunglasses because they may make your chin look so small. For heart shape faces, we recommend cat-eye sunglasses, round sunglasses, and also square sunglasses.

All of our wishes is overcome Covid-19 this year. But during the period, we have to wear a mask while in public to avoid spreading Covid-19. When going to the grocery stores, supermarkets, and restaurants, masks are must-have now.

We’ve made some simple tips to help those who wear glasses avoid glasses fogging up when wearing a mask.

-Be sure your mask is fitted your face well

When the air inside your mask escape, your glasses may easily fog up. For colder weather, the situation can be worse. Things can be better if you can get ahold of a pipe cleaner and make a DIY to add a piece to the top of the mask. Then the mask can be fitted well.

-Wash your glasses with soap before wearing it

Before wearing your glasses, you can wash them in soap water. And make sure to shake off all the soap water remaining.  After then, use the cleaning cloth to wipe it dry. It may do some help to reduce the fog possibility when wearing a mask.

-Adjust your glasses and mask in the proper position

You can make an adjustment of your mask a little lower to reduce the fog of your glasses. But if you have a high prescription, that might work since it may affect your eye vision. One thing please remember, do not touch your face, nose with dirty hands.

Once we mentioned winter, we may think about hats, scarves and gloves. They are no doubt basic necessities in winter. However, few of us think about sunglasses. Sunglasses are more like summer equipment, don’t they?  That’s in fact not right! As for everyone, protecting our eyes in winter is as important as in warm seasons, since ultraviolet radiation is so dangerous to our eyes, especially from November to March.

In summer, sunglasses are an essential part of your travel equipment. Not only because the sunglasses look fashionable, but also because they protect our eyes from strong light. However, many of us do not realize that harmful ultraviolet rays are much more dangerous in winter than in summer. In summer, the green environment reflects only about 6% of the light, while for snow, this number is close to 96%. Only sunglasses equipped with high-quality lenses can provide effective protection for our eyes and prevent eye inflammation or more serious conditions. This is because the sunlight contains high ultraviolet energy, which can cause retinal damage. All these indicate that high-quality sunglasses is a wise investment for all seasons.

Blue light glasses are gaining in popularity and as we wear them more and more they need to be clean to provide the best acuity possible. We will give you some expert cleaning tips for your computer glasses or blue light blocking glasses.

First of all, I’m going to tell you how to clean your computer glasses. Computer glasses are a type of blue light glasses that filter small amounts of blue light during the day. As their name suggests they are to be used while working on a computer and filter down on harmful blue light. These computer glasses typically do not have a tint applied to their lenses, instead, they have blue light filtering technology applied to them or impregnated into the lens itself.

The best way to clean these types of glasses is by two methods. One is our preferred method make a warm bowl of water and dip your blue lights computer glasses into them and rub the lenses with a clean dishcloth. We like to have warm water poured into a clean bowl for hygiene purposes then leave your glasses to dry for a few minutes and then drink gently, rub them dry with the blue blocks cleaning cloth provided. The second method actually works very well at cleaning computer glasses itself but I have the caveat this involves chemicals that we’re not too excited about. I personally don’t like to use them, but if you want to use them it’s totally up to you. Your optometrist will sell lens cleaning solutions that could be sprayed onto your blue light computer glass lenses and then gently rubbed clean with the blue blocks cleaning cloth that has been provided. This will probably give you a better result than option one.

Now let’s get on to how to clean your blue light glasses. Now, these will be either your summer glow yellow lenses from blue blocks or your red sleep Plus lenses from blue blocks chances. Are you already have a pair of the best polite glasses from blue blocks. But now you need to know how to clean those blue light glasses in order to properly care for them and allow them to last forever. Most blue light-blocking glasses have lenses that have been tinted. This tint must be cared for and maintained in order for your blue light glasses to last a long time. There are two ways again to clean your blue light glasses. NO.1, run the tap or to my American cousins the faucet on hot option until you see some light steam arise, place your blue light glasses near to the steam turning them around to ensure the lenses fog. Ah, don’t put them directly under the hot water, that would not be a good idea. Turn off the tap faucet and then gently clean your blue light glasses with the blue blocks cleaning cloth provided. Do not use boiling water just light steam is required. NO. 2, make a warm bowl of water and dip your blue light glasses into them and rub the lenses. Clean with the dishcloth like we did with the blue light computer glasses. We like to have our own warm water poured it into a clean bowl again the hygiene purposes you don’t want to be putting it in a bowl that has food in it. Then leave your glasses to dry again for a few minutes and drop gently rub them dry with the blue block cleaning cloth provided.

Either of the above methods works really well but for sterilization and hygiene purposes option one is always the preferred option. So in order to maintain the integrity of your blue light glasses from blue blocks and also your computer glasses from blue blocks. It’s best to know how to clean these glasses properly, this will ensure that they last a long time and continue to protect your health optimally from the dangers of blue and green light.
