How to put on screen protector: 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.
Then use the same method to pry the other three corners of the screen protector, and use a little more force when smashing, so that the four sides of the screen protector can be pulled up. After the four corners are picked up, grab the lower corner and pull up. Then the whole screen protector will start to loosen, and then pull up the four corners until it is removed. Congratulation: the task of removing the old screen protector is now completed. At this point, the screen protector will automatically stick to the screen and slowly expand to the surrounding area. Take out the squeeze card, press the edge from the top to the bottom, and drive the bubbles away. Discover even more details on how to apply tempered glass screen protector without bubbles.
Dry eye can result in a series of problems with your eyes apart from making your eyes irritated or itchy. Although dry eyes can be linked to your age, you can take measures to prevent it, like using eye drops or turning on the humidifier in your home or office to relieve the condition. If it persists, you can contact your optometrist for advice or treatment. You may have to stop diuretic medicine. If you walk in the sun often or the nature of your work requires spending a few hours in the sun, protect your eyes by wearing sunglasses to protect your eyes from the ultraviolet rays that come from the sun. The ultraviolet rays can damage your eyes. Why endangering your eyes when you can get a good pair of sunglasses for a few bucks?
Your glasses and contacts: Talk with your optometrist about purchasing eyeglasses or contact lenses with HEV filters already built in. It’s a good idea if you plan to use your devices all day, without many breaks. You can also wear special computer glasses. TrueDark is an eyewear company that sells blue-light blocker glasses that look just like regular glasses. The company just announced two clear-lens blue-light filter glasses that block around 40% of high energy visible light. TrueDark also produces special night-time glasses that filter out all high energy visible light that you can wear over your glasses to block out 100% of blue light caused by LED lights, devices, and streetlights an hour before bedtime for optimum sleep.
What is blue light? Sunlight contains red, orange, yellow, green and blue light rays and many shades of each of these colors, depending on the energy and wavelength of the individual rays (also called electromagnetic radiation). Combined, this spectrum of colored light rays creates what we call “white light” or sunlight. Explore extra info on www.perfectsight.co.
