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.
The Different Types of Screen Protectors, First: Tempered glass screen protector. Tempered glass also called toughened glass belongs to safety glass, which plays a good protective role for mobile phone safety. Its characteristics are explosion-proof, scratch-resistant, wear-resistant, and the hardness can reach to 9H (even stroked with a knife), prevent the rupture of the tempered glass caused by accidental impact of the mobile phone from harming the screen and the human body. Easy to paste, no bubbles, the screen transmittance is up to 93%. It can prevent the harm of electronic waves to the human body. Feels better when used with sensitive touch.Explore extra details on anti glare screen protector.
Understanding the physics of light and how it interacts with the human eye is the first step to understanding why too much of it can be bad for us. All light is waves, and different colors have different energies. Towards the beginning of the visible spectrum is red light, made up of low energy waves. This light is easier on our eyes, especially at night. As we get closer to the higher energy side of the spectrum, light becomes more tiresome for our eyes to process. Blue light occupies the highest energy portion of the visible spectrum. It penetrates all the way to the retina in the back of the eye.
Scheduling a yearly eye exam is one of the best things you can do for your overall health! Besides addressing the obvious (such as a change in vision), an eye exam can often lead to the diagnosis of more serious conditions including diabetes, high blood pressure, and even cancer. What’s more, an eye exam will allow the doctor to check for eye conditions that may go unnoticed by the patient. Often patients diagnosed with glaucoma only become aware of their condition after having already suffered permanent vision loss. Because there are no symptoms early on, it can easily go undetected without a routine eye exam. It is also important for young children to have routine eye exams, as their vision more strongly influences their ability to learn and comprehend the world around them.
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. Read more details at perfectsight.co.
