The answer is yes but only when it falls directly into your eye. Otherwise, the reflective does not affect your so the chances of any damage or issue is almost nil. If a projector is used in the way it is intended and it is used adequately with its accessories like screen, then there is no chance that anyone will face eye damage. It is a general concern that circles every first timer’s mind who are about to buy a projector for home entertainment, primarily when it is used around children.
Most of the projectors, including professional ones, give out a lot of IR and UV light during projection, so if someone without a rational mind looks directly into them, then it would affect. Adults need to take care of kids and prevent them from looking directly into the lens as kids are unaware of the side effects.
The light source of most of the projector’s stays around 6Kw, which is entirely unsuitable for human’s eye. You should remember a certain glance won’t damage, but a prolonged stare would definitely cause issues. Moreover, if there is a difference in contrast, then it will not only cause discomfort but will also affect the eye to a certain extent.
However, these lights are almost filtered when they reach the screen, and they turn into visible light, so when you look at the screen, you won’t get any strain. When you use an excellent display screen and proper setup, then there is a minimal chance that striking light would damage your retina. This fact is also applicable for kids because your kids will be already habituated to the blink reflex to abnormal bright lights.
Do projectors emit blue light?
Unfortunately, the answer is yes. The emitted blue light may not seem strong, but due to shorter wavelength, they hold a lot of prowess.
So when your eye is directly exposed to the light, due to the high intensity, it will pass through the top layer and hit right into your retina, causing pain and sometimes severe damage. Prolonged exposure to blue light will also lead to eyestrain, fatigue, pain, and dry eye. Cumulatively these issues can cause damage to the retina cell, which causes degradation in vision.
Can Laser Projectors Damage Eye?
However, you can’t say the same if you are using Laser light projector as the chances of laser projector eye damage is zero. The main reason is that the laser projector mostly produces visible light, and they are low on power, so it makes them totally healthy for viewing.
Moreover, the laser light capacity used in projectors is below 5mW, so it doesn’t have any ability to do any harm the health of your eye. However, looking directly for some time might cause passing blindness, and you will gain vision within seconds.
So we can conclude,
“if you can use your projector wisely and avoid any direct eye contact with the emitting light, then a projector light won’t damage your eyes.”
Follow proper safety measures and enjoy quality entertainment time with your family and friends.
Before bidding goodbye, let’s take a quick look at certain crucial safety measures;
Safety Precautions for Your Eyes When You Are Looking at Projectors
- Prevent your kid and anyone to stare directly into the lens as it emits a large amount of light from the small area.
- Remember opening up the projector foolishly while it is working without proper eye gear can temporarily or permanently damage your retina. As the light is not filtered and there is always leakage of UV rays, it can cause eye burn followed by momentary blindness. So switch off the projector before commence on opening up the panels.
- Always use proper accessories like appropriate screens, good mounts, and other components to minimize any chance of exposure. Likewise, avoid sitting to close to the projector and maintain a preferable distance from it.
- It is always better to mount it in the ceiling or at a place so it can prevent maximum eye contact.
- While providing a presentation, maintain a distance from the light as it will prevent your eyes from getting affected by the harmful rays.
- You should follow 20-20-20 rules for eyes when you are playing games or watching movies on a projector for a long time. Not only for the projector, but it is also useful if you are seeing any kind of electronics devices for a long period of time.
