Tempered glass screen protector purchase advices: Because short-wavelength, high energy blue light scatters more easily than other visible light, it is not as easily focused. When you’re looking at computer screens and other digital devices that emit significant amounts of blue light, this unfocused visual “noise” reduces contrast and can contribute to digital eye strain. Research has shown that lenses that block blue light with wavelengths less than 450 nm (blue-violet light) increase contrast significantly. Therefore, computer glasses with yellow-tinted lenses may increase comfort when you’re viewing digital devices for extended periods of time. The lens in the adult human eye blocks nearly 100 percent of the sun’s UV rays. As part of the normal aging process, the eye’s natural lens eventually blocks some short-wavelength blue light as well — the type of blue light most likely to cause damage to the retina and lead to macular degeneration and vision loss.

How to install a screen protector perfectly without bubbles and alignment tool ? Warm Tips: Before the installation,please make sure the doors and windows are closed.Try to keep the invironment clean and avoid the occurrence of dust or lint. Take out the new screen protector, wipe it with a cleaning cloth, make sure there is no dust on the outside, then grab the top of the backboard and then tear off the screen protector. Put the upper part on the phone screen, first align the upper part of the screen protectoe with the upper part of phone screen, and compact it slightly. See additional info at how to install screen protector.

Allow distance. Being too close to your screen is also a factor in how your eyes can be negatively affected—they have to work harder to see things that are closer. If possible, keep your monitor or screen about 25 inches away, or about an arm’s length away. Make sure to position the screen so your eye gaze is directed slightly downward. Adjust the brightness. When a screen is much brighter than the surrounding light, eyes have to work harder. If you can, adjust your room lighting and try increasing the contrast on your screen.

We can also expect to see new phone releases later this year that integrate blue light-reduction dye, and the Consumer Electronics Show in January 2019 will show off commercial grade products which incorporate these features. Product designers should help accelerate this change by working with companies to integrate HEV-blockers right into the screens of the products they create. Also consider indicator colors on connected electronic devices; a warm orange will always be more welcome than a bright blue. Until the tech industry fully addresses the problems caused by blue light, there’s a number of steps we can take — in our household, and in our civic halls.

Visible light is much more complex than you might think. Stepping outdoors into sunlight; flipping on a wall switch indoors; turning on your computer, phone or other digital device — all of these things result in your eyes being exposed to a variety of visible (and sometimes invisible) light rays that can have a range of effects.

Blue light filter: But too much exposure to UV causes a painful sunburn — and even worse, can lead to skin cancer. These rays also can cause sunburned eyes — a condition called photokeratitis or snow blindness. But ultraviolet radiation, in moderation, also has beneficial effects, such as helping the body manufacture adequate amounts of vitamin D.

Anything above 380 nanometers is not visible to the human eye and cannot be seen. While invisible, these frequencies can still be useful. Some epoxies used in dental work use ultraviolet light to accelerate the chemical process of fixing teeth. Tanning beds use these frequencies to artificially increase tan color (though of course you wouldn’t want to be bathed in it for hours, or you could develop significant health problems).

PERFECTSIGHT MacBook Pro 16 Screen Protector Warm Tips: To help cut the glare, reflection, blue light and UV ray from Apple MacBook, this screen protector has a slightly “frosted” look – matte. But if you’re looking for a crystal clear optical screen (and the eyestrain that goes with it), you might want to be aware of this before you buy. If you care about the future health of your eyes and it will aid helping further deterioration. I know it’s somewhat costly, but it’s nothing compared to the cost of your eyes. Discover a few more info on MacBook Pro 16 screen protector.

Eye tip: This one should come as no surprise – the food we put in our bodies plays a vital role in our health. You want to be sure you’re eating foods with plenty of nutrients including omega-3 fatty acids, Zinc, Vitamins A, C, & E. Here are some of the foods that contain these vision-enhancing nutrients: Omega-3 Fatty Acids, which can help to reduce the symptoms of dry eye, can be found in several natural food sources including salmon, mackerel, tuna, walnuts, chia seeds and tofu.

The amount of HEV light these devices emit is only a fraction of that emitted by the sun. But the amount of time people spend using these devices and the proximity of these screens to the user’s face have many eye doctors and other health care professionals concerned about possible long-term effects of blue light on eye health. The short-wavelength, high-energy light rays on the blue end of the visible light spectrum scatter more easily than other visible light rays when they strike air and water molecules in the atmosphere. The higher degree of scattering of these rays is what makes a cloudless sky look blue.

Best printers of 2020, which one is the most efficient? Since the printing technology introduced its popularity and importance have increased year over year. Now it has become the most common device for each business. It depends on the business type which printer to use. Printing technology can save our lot of time by not wasting time making official reports manually. So the importance of a printer cannot be overstated. Today we are going to discuss the importance of printing technology in various fields. To get the importance of the printer, you have to study its usage. The printer can be used for various tasks in various industries or businesses. The below-given statement can prove the importance of this fantastic technology.

The inkjets, together with their pigment-based and dye inks are known to perform well when it comes to handling colour for specific photos and images that are most likely to involve the colour subtle shades. The nature of the ink means that it is straightforward to produce all the mixtures on the inkjet printers as it is to provide them on the laser printers. Photo printing is suitable for the laser printers. Even the laser printers are in a position of handling higher quality colours when it comes to photo printing that does need a specialized laser printer that makes it less convenient when it comes to using the standard paper on the inkjet. The laser printers are much-suited t text printing offering precise letterforms, offering crisp which can be matched by majority of the inkjets. In most cases, the inkjet printing will always bleed, and as print is legible, the letters will never be that sharp in their detail when they are checked at close range.



By using a 3D Canon printer, one can create a numberless model of any design, no matter how tough or complicated it is. One just has to create the blueprints in CAD software, and the machine will produce what you exactly want. The other conventional methods will take up to a few weeks to create an exact model of the object. But the 3D printer has the efficiency to produce digital models within a few hours or a couple of days. So that it increased the production level. It is costly to own or install a 3D printer. But it is also very affordable as compared with the maintenance, labour cost and manufacturing costs of other conventional methods. The value of manufacturing models with a 3D printer is equal to mass manufacturing.

Is the A4 format sheet similar to 8.5 x 11 inches? No, there is a difference in size. Only the American countries are using 8.5 X 11 inches sheets as the standard letter size. The rest of the world uses A4 format to print their office documents, letters, etc. Whenever we have to use a printer paper, the size matters a lot. We cannot print a big image on small paper or vice-versa. Hence, it is better to check the size or resolution of the document you are going to print. It is quite essential to use the appropriate size. Hence we have mentioned a few above. You can select from all the sizes that we have mentioned above. Many manufacturers in the market can help you to purchase the best product at an affordable rate. Therefore, it is better to research before buying a one for you.

What is a mono laser printer? Mono Laser printers refers to machines that are tasked with printing of images and texts from the computers using a laser beam that helps in controlling the area where a particular color will be applied to on the paper. The Mono laser printers are much faster when compared to other printer types and they are in a position of producing a huge number of white and black documents at a cheaper cost than on the other printers.

Space engineers and aerospace normally use 3D printing to make parts that perform well. They do have the ability to come up with an optimized topology. There is also the possibility of consolidating several parts into one big part which will be appealing. For example there is a company that specializes in offering micro antenna products for defense and aerospace applications. The company uses 3D metal printing to help in reducing the discrete pieces when tracking arrays on antenna from 100 to 1. There have been great benefits in the automotive industry from ease of customization and quick turnaround provided by 3D printing. In the past, Volkswagen did use CNC machining to help them come up with custom fixtures and jigs. CNC is known to have a longer production time and its cost of operation is also quite high. It is possible to print similar jigs and fixtures same night and have the tests done the next day. Operators’ feedback was put into place with immediate effect and there was a new jog that was ready for testing.

Are you an anime lover? We’ve got you covered. The Funimation NOW add-on is totally legal and has a great selection of anime to stream right now. This add-on is legal and also available from the official Kodi.tv repository. Ready to install? Easy Kodi Add-on Install Instructions. Discover additional details on Kodi addons.

Rather than installing Kodi add-ons individually, you can install a Kodi repository that contains multiple add-ons that could all be to your liking. With a repository, add-ons are continually updated once a newer or better version has been released. When you receive instructions to install a specific Kodi add-on, more than likely, those steps will involve installing a specific repository that will include other add-ons that you can install in addition to the one that you want. Kodi repositories are also installed like individual add-ons, through a .zip file within the Kodi settings panel.

We can break efficiency down into a few parts here. First, the server that you’re playing on still has to render the grunt of the work: the graphics. So there’s not much in the sense of energy savings here. But now there’s an added element: an EXTREME amount of data necessary to transfer over the internet. When I say extreme, I mean somewhere in the ballpark of 20-30MBPS of data (that’s a lot) continuously. This is all fine and dandy if you don’t plan on playing all the time since most internet providers have a data cap written somewhere in their contract (Typically around 1 terabyte of data per month). To put this into context, a 5MBPS connection is capable of over 1.5 terabytes of data per month if used constantly. Imagine how quickly you’ll eat through your data at upwards of 30MBPS. It doesn’t take long to see an issue here. Now, this only applies to people who have data caps. If you’re one of the lucky ones that have unmetered internet, then cloud gaming may make a lot of sense. Read even more information at Android Kodi and TV boxes.
