We often see blue light protection film on digital cameras and cell phones – but do you actually need blue light protection for your computer? NO. In reality, blue light protection glasses protect your eyes from all the harmful effects of blue light, which are basically the same kind of light that is emitted by many electronic items, such as laptops, phones and tablets. The blue light protection film works by blocking out blue light – which is just the same as turning off your computer’s monitor and TV in order to prevent glare and eyestrain.
How much protection is needed is determined by how vulnerable your human eye is to UVA rays. Ultra-violet rays can penetrate the skin of the human eye and cause severe damage. One study showed that even a small amount of ultra-violet radiation can cause cataracts or loss of vision. So, it is important to have adequate blue light protection.
There are two kinds of blue light: visible light and high-energy blue light. Visible light has been known to cause serious damage over time. However, the human eye itself is not sensitive to blue light. If exposed to visible light over an extended period, blue light macular degeneration may occur – this can lead to age-related blindness and can eventually lead to blindness due to UVA exposure.
High-energy blue light is emitted by UV rays from the sun. Long-term exposure can also cause cataracts and loss of vision. It is important to use protective shades and other methods to avoid prolonged exposure. Some manufacturers even provide blue light reduction technology that reduces the amount of time that you are exposed to blue rays. However, while reducing the amount of ultra-violet rays emitted by the sun, these devices do not help block UVB rays. They only reduce the amount of blue light.
Another way to prevent damage to your computer is to have a high energy visible light screen protector. These products are often referred to cocoons blue light computer screens. When using computers and working with blue light – cocoons blue light computer screens can actually decrease how long you are exposed to the harmful rays. Some manufacturers recommend using these screens for no more than 20 hours a day to increase the possibility of reduced exposure to harmful UV rays.
Many people are unaware of the fact that they are exposed to high-energy visible blue light every time they use their smartphones, tablets, laptops and other portable devices. Their eyes are constantly exposed to these ultra-violet rays. In order to increase their chances of avoiding blue light damage, you should try to avoid sitting close to windowsills, stands, TV sets and other sources of natural sunlight. If you must use a table lamp, make sure you place it so that it does not shine directly into your eyes or onto the computer screen. Sunlight can be reflected away from your screen and can potentially cause damage to your device.
If you need to use your smartphone, tablet or laptop in direct sunlight, turn it off when you leave the room and/or purchase a case that has some type of UV or HEV protection. There are several types of pediatric eye care available. Some are offered as an add-on to existing covers. If you frequently use your smartphone, iPad or laptop outdoors, you should look into purchasing one of these protective cases to keep yourself and your device safe.
These harmful UV rays are especially dangerous to younger children who have poor eyesight. Studies show that children who spend a lot of time indoors, such as doing homework, watching television and playing video games, may be at higher risk of developing eye fatigue. When their eyes to become fatigued, they may find it difficult to focus. In addition to this, if their parents spend a lot of time outside, the child will also be exposed to increased amounts of ultraviolet rays. Preventative measures, such as wearing sunglasses or goggles, can help protect against eye fatigue, allowing kids to play safely as well as see better.
