about protective goggles

June 16th, 2015

Protective goggles are form of protective eyewear that usually enclose or protect the area surrounding the eye in order to prevent particulates, water or chemicals from striking the eyes. They are used in chemistry laboratories and in woodworking. They are often used in snow sports as well, in cycling and in swimming. Goggles are often worn when using power tools such as drills or chainsaws to prevent flying particles from damaging the eyes. Many types of goggles are available as prescription goggles for those with vision problems, such as driving goggles, swimming goggles, ski goggles and so on. Take swimming goggles for example, it must be watertight to prevent water, such as salt water when swimming in the ocean or chlorinated water when swimming in a pool, from irritating the eyes or blurring vision. Allows swimmers to see clearly underwater. They will not be usable more than a few feet underwater, because the water pressure will press them tightly against the face.

The history of swimming goggles dates back at least to the 14th Century, when writers described Persian pearl divers using goggles with windows made of the polished layer of tortoise shells. That these goggles were possibly imported to Mediterranean countries can be deduced from the 16th Century illustration of Venetian coral divers using goggles. Goggles mysteriously disappeared from use, possibly because enslaved American Indian and African divers, who did most of the world’s commercial diving from the 16th Century onward, did not use goggles. Polynesian skin divers were known to use bamboo or goggles carved of wood. Originally, these wooden goggles had no lenses, but trapped air when the face was down, forming an air bubble over the eye that enabled the divers to see clearly when submerged. With the introduction of glass, the Polynesians added lenses.

If you are a novice, choosing the best swimming goggles for your needs can be a frustrating experience if you do not know what to look for at the sports store. It is advisable that you try on the swim goggles you are interested in, ideally the exact pair that you’ll be buying. Nothing is more frustrating than having bought a new pair of goggles that is uncomfortable or useless because it leaks. Now push the lenses some more against the eye sockets, then release them. The goggles should stick on your face a few seconds thanks to the suction, even if the straps are off. If this isn’t the case and the swim goggles fall off, they will leak water and be useless. If the goggles pass the first two tests, put the straps on and see if the goggles are still comfortable. Check if the lenses don’t suck too much on the eyes or that the straps must not be tightened too fast.

Four Aspects You Should Notice When Choosing Swimming Goggles

April 13th, 2011

Swimming goggles can not only protect your eyes from being damaged by the substance in water but also provide you a good visual field under water, enabling you to swim freely. However, improper choose or incorrect use of swimming goggles cannot protect but damage your eyes. So it is necessary to take all aspects into consideration while selecting swimming goggles.

1.      Optical performance and medical standard

As the refractive index of water is different from that of air, if the surface of the swimming goggles is uneven it is like wearing convex lens or concave lens, which will cause damages to your eyes over time, thus affects your vision. A pair of high quality lenses should meet the optical and medical standards, namely the lens degree above water is the same as that under water, the object seeing through them does not distort and the visual field is wide.

2.      Comfort

The swimming goggles shall be designed to conform to the principles of Ergonomics. Small swimming goggles are suitable for westerners as their eye sockets are sunken and the goggles are right embodied in their eyes. Big framed swimming goggles are the better choice for easterners because their faces are usually flatter.

3. Antifogging performance

The water around the swimming goggle is colder, so the air inside the swimming goggles is likely to condense into water on its inner wall, thus fogging which will prevent you from seeing things clearly. For this reason, it is significant for the swimming goggles to have the antifogging performance.

3.      Appearance and package

With the upgrading of people’s taste and the spring up of personal style, the swimming goggles are not used only for protecting eyes any more but for meeting the requirements of fashion and beauty. Different people should wear different styles of swimming goggles in different occasions. The shape of swimming goggle should be designed according to the fluid mechanics so as to reduce the resistance in water. In addition, stylish appearance should also be integrated properly. As for colors, black, blue, silver and yellow are better.

If you want to choose a proper pair of swimming goggles you should take the above four aspects into consideration while selecting. Have you remembered them?

Generations of night vision goggles

May 6th, 2010

Night vision goggles are the collective name for the optical devices in the form of wearable glasses, goggles, binoculars as well as telescopes, for the purpose of seeing objects in the darkness. Night vision goggles are widely used by armed forces, rescue teams, property security, local law-enforcement and even for fun by hobbyists.

Night vision goggles can be categorized as active and passive systems. The active night vision goggles cast infrared light to an area enabling the wearer see the objects in that area at night. The passive night vision goggles gathers the very dim light from nearby and amplify the image signals via electronic systems so that the viewers can identify things from the screen.

It is believed that there are 4 generations of night vision goggle till now. The first generation is called generation 0, which are the active infrared goggles. These night vision goggles were first used by US Army in WWII. Later Germany developed the same night vision goggles which were outfitted in Nazi forces. As these active night vision goggles can be easily seen by enemies, they were gradually phased out in the Vietnam War.

Gen 1 is the first ever passive type of night vision goggle, which were first used in the battle field of Vietnam War. By adapting old technology and using new intensifier with light amplification of 1000x. Gen 1 gets rid of the active infrared, but still need pretty strong moonlight to aid to see the objects. Gen 2 night vision goggle further use new technology such as micro-channel plate to achieve much clearer image resolution even in pitch darkness. The light amplification reached 20000x. Gen3 even further increase the visibility, image resolution and image reliability, and achieved 30000-50000x light amplification.

One sub-model from Gen 3 worth mentioning is Omnibus-VII. Night vision goggles in Omnibus-VII use the new out-gating technology enabling the night vision goggle change as fast as light changes, and can retain the stable visibility even when being exposed to very bright light at a sudden.

How were night goggles invented?

December 16th, 2009

Night goggles are the optical instruments enabling people to see in the darkness. Before inventing night goggles, people knew that some creatures living and hunting at night can capture more light and see better than human does. People knew these animals have different eye structures, but physiologically scientists could not arm human with the same eye system as animals’, so scientists started to think about electricity.

Electricity is easy to be amplified. When the lenses of night goggles capture the light from vicinity, the electronic system in the night goggles turn the dim light into electronic signals, then amplify the signals to much greater scale, and finally turn the boosted signals into light image. This new clearer image can be seen by the user of night goggles on the small screen of the night goggle.

The principium of changing the dim light entering the lenses of night goggles to electronic signals is pretty similar to the principium of solar panel, but the for former is more precise and more sensitive.

The image we see finally on the night goggles screen is of green color. Actually when the light image is boosted in the night goggle, the colors are in black and white. The green color is intentionally added to the new image as human eyes are more sensitive to the green light, so viewers can see better in green. Also looking at green images makes viewers feel easier for extended long time viewing.

Night goggle is now used in military forces and civilian areas, people finally realized the dream of seeing objects even in the pitch darkness.
