With weather getting warm, plans for vocation in early spring should be placed on agenda. Then a pair of polarized sunglasses must be a necessary accessory, and if you have myopia or hyperopia, prescription polarized sunglasses of different colors are strongly recommended.

The so called prescription polarized sunglass is a great combination of prescription glass, polarized glass and sunglass, which can be easily observed from the name. It indicates that, wearing prescription polarized sunglasses, without contact lenses, you could get a clear vision and at the same time keep your eyes from both harmful sun rays and reflections from water and mirror, etc.. Isn’t is a good way to kill more two birds with one stone?

Then, when choosing prescription polarized sunglasses by color, you must feel dizzy, for there are really a great many kinds of colors. Which kind should you choose?

The first principle people notice when choosing the color of sunglasses should probably be whether it matches with their skin colors or not. However, apart from this principle, for the goodness to your eyes, you should choose the color of sunglasses according to the function each has.

As for the color depths, they can be divided into that of 15%, 34%, 50% and 70%. The darker the lenses are, the more visible light will be absorbed, but the color depths are irrelevant to the capacity to block ultraviolet radiation, which is merely related to materials of the lenses.

The functions vary from one color to another. Gray lenses can absorb any kind of color spectrum, therefore, no aberration will be produced. Vision for gray sunglass wearers will merely get darker. Coffee lenses are able to eliminate a great many of blue light which could improve the sharpness of vision, so sunglasses with coffee lenses are suitable to be worn in environment where air pollution is severe. Green lenses, similar to gray lenses, are capable to increase the green light reaching to eyes, which would bring cool feeling to the wearers. Yellow lenses are also called night vision lenses. They are hardly able to increase visible light, but instead improve contrast ratio. Thus sunglasses with yellow lenses are strictly not included in sunglasses. They are more preferred to be referred as night vision glasses.

Then, with the above knowledge, facing prescription polarized sunglasses of different colors, you could choose the right color and depths of that suitable to your lives most. Just have a try.

What are toric lenses

May 8th, 2010 by Reza Hyver No comments »

Toric lenses are particularly for astigmatism. While spherical contact lenses correct nearsightedness or farsightedness, toric lenses are designed to correct astigmatism, a corneal astigmatism or lenticular astigmatism as well as a combination of them.

Astigmatic cornea is deeper in one direction and flatter in the other. In other words, the cornea may be more oval-shaped than spherical or round-shaped. Is this case, regular contact lenses can not correct all of your vision problems. Toric lenses are the right solution since they are designed to give your eyes more power in one direction and less in the opposite direction. Once you are comfortably fitted, toric lenses can correct your astigmatism.

Toric lenses are special in lens design. Unlike regular lenses, they have two powers, created with curvatures at different angles. One of them is for astigmatism and the other for myopia or hyperopia. So that toric lenses can correct both of them. In this design, toric lenses are truly the special products for people who are astigmatic and also need far vision help or near vision help.

Toric lenses have no difference in material with regular contact lenses. In the early days, people having astigmatism may be told that they were not suitable to wear soft contact lenses. It is not true today. Toric lenses are available in soft and rigid gas permeable (RGP) types. Soft toric lenses are more comfortable than RGP lenses. A small percentage of patients prefer RGP toric lenses over soft contact lenses, because RGPs maintain shape on the cornea better than soft ones.

May 7th, 2010 by William Krause No comments »

Glasses eyes can be made in full, like real natural ones. The glass eyes take the shape of a convex shell, and have the similar size of real ones. Of course, glasses eyes are made according to the characters of different individuals. For instance, the average size of the human eye is 1 inch overall diameter. But there is not accurate same size between different persons. What is more, the colors of individuals’ eyes are different. So glass eyes must be made in abundance of choices.

As people know, glasses eyes do not provide vision; someone with glasses eyes is totally blind on the affected side and has monocular vision which affects depth perception. So people will take the glass eyes in the condition that they have damaged eyes and have to take a surgery to remove the eye. One takes the glass eyes in the purposes of health and more natural looking. Commonly, the proper glasses eyes look real and nice. For people create glasses eyes with perfect iris and eye coloring to make glasses eyes look realistic.

In current days, glass eyes are extensively made by machine in a wider variety of size, shapes and colors and different modes. For example, Toys often have sewn-on glasses eyes, and machine-made glass eyes satisfy the properly purposes. In addition, the materials of machine eyes can be plastic. Many companies make eyes from a kind of polyglass, which is a combination of plastic and glass.

Generally, glass eyes make a great contribution as artificial eyes to people’s lives.

Generations of night vision goggles

May 6th, 2010 by Randa Fritch No comments »

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.
