Night vision devices are not used in daily life. The exploration of night vision goggles in the movies and video games have developed an interest in the people to see the things in the darkness. Night vision devices (NVDs) are being used for some special purposes including military, hunting, security, and exploration missions.
Many people have a question their mind when they start researching about the NVDs that whether night vision devices can damage your eyes or it is safe to handle. The answer to this question is that night vision is safe for your eyes if you have well collimated and calibrated device in your hand. After the teenage, only physical activity can damage your eye or make you a permanent blind. The weakness of the eyesight is another prospect which is related to the misuse of certain things. However, the night vision devices are safe for your eyes and there is no harm associated with their usage.
Special usage of the NVDs
NVDs are used for some special purposes and under special circumstances. You are not going to wear a night vision goggle 24/7. So, there is a rare chance that the night vision would damage your eye. Some people have an obsession with the green light and they may find it hard to handle the night vision goggles. It is their own drawback and it does not have any link with the impact of night vision on your eyes. The lesser time to be spent with the night vision devices makes them unharmed for the kids and other users. Many people associate their permanent and previous eyes issues with the night vision devices. Night vision is not a reason behind the damage of the eyes, according to research.
Impacts of extended use of the NVDs
A study has been conducted by the experts of the Army Research Laboratory and it found that the extended use of the night vision devices did not impact badly on the comfort level of the participants. The participants felt muscular pain due to the extended use of NVDs. The pain occurred as they lifted the goggles for a longer period of time. The study proved that the night vision devices did not have any negative impact on the eyes. The study found that the extended use of NVDs caused headaches and eye strain. I would like to recommend you to use the night vision devices when it becomes necessary to use them. These are the side-effects of the extended use of the night vision devices. Still, they are safe to use when they are needed to be used.
The green color is safe for the eyes
The green color is the most appropriate color for the night vision goggles and other devices. Many people ask a question that can night vision goggles blind you. The answer to their question is no. The green color is less intensified color and it is safe for the human eyes. The night vision devices cannot damage the eyes in any way. The US Army marines use night vision goggles during the operations and they wear them for several hours at night. According to the research of the Army Research Laboratory, the US marines do not have any negative effect on their eyes during the operations. Some side-effects were noticed during the research but the night vision did not damage the eyes. Moreover, the green color of the night vision devices is due to the use of phosphor. The green color is safe for the eyes and it does not have any negative effects.
Does Night Vision hurt your Eyes?
Many people have a question in their mind that does night vision hurt your eyes? Let us discuss the working principle of the night vision devices before getting to the answer to this question. Night vision devices work on the principle of capturing the infrared rays emitted by the bodies in the form of heat. Thermal imaging technology is used in this regard. Infrared rays are dangerous for human eyes in an intensified form but the night vision devices capture appropriate amount of the infrared rays with the aid of thermal imaging technology. So, the amount of infrared rays captured by the night vision goggles is safe for the human eyes.
Can Night Vision Goggles Blind you?
The answer to this question is no as the night vision is completely safe for the human eyes. The permanent blindness occurs only due to the physical injuries to the eyes after the teenage. The night vision goggles and other devices are used mostly by the people above the adult age. The working principle of the night vision goggles makes them safe as well. The green color is the most appropriate color to be viewed by our eye that is why it is used in the night vision. There are no chances of being blind due to the use of the night vision goggles.
Some side effects of the Night Vision
The night vision devices are safe for the eyes as no case have been reported so far in which the eyes were damaged. There are some side-effects of the extensive use of the night vision goggles including:-
- Limited field of view
- Temporary blindness due to the weight of the night vision devices
In some cases, a loss of dark adaptation was reported. The technologists worked hard to mitigate this issue. The use of the optical filters helped them to overcome the issue of the loss of night adaptation. The issue occurred due to the high output of the NVDs.
Night vision is based on a safety working principle. There is no harm in the use of night vision devices. The infrared rays, thermal imaging technology, and green visual spectrum are safe for the human eyes. The scientists are working hard to minimize the side effects of the use of night vision goggles in the military and hunting practices. If you have the concerns related to the use of night vision devices then you need to put them out of your mind. The use of the optical filters is recommended for the airmen, aviators, and commanders for getting better results from the NVDs and protecting them from the loss of dark adaptation.
