Laser eye protection is to protect the eyesand attack, in short, the laser is able to prevent or reduce the laser damageto the eye of a special glasses. Laser is an efficient safety goggles, suitablefor a variety of lasers, laser pen, a series of optical safety glasses, wearingcomfortable, beautiful, safe and reliable. Below small make up with us to talkabout the eyes for us is more important, not only to see the light, mottled withthe world can give you a different visual effect.
Eye shape to spherical, called the eye. Theeye has many of the forms: some 1, the eye wall, 2, fiber membrane, 3, 4, 5cornea, sclera, and vascular membrane, 6, 7, iris, lens, 8, 9, choroid, retina,10, (11 eyes), blind spots, iris, ciliary body, 12 Part 13, 14, and 15,membranous thread head, contents, 16, 17, aqueous humor, lens, vitreous body,18 eye wall is a layer arrangement surrounded by eyeball, composed of sclera,choroid and retina. The external wall of the eyeball can be divided into threelayers: the fibrous membrane, the pigment film and the retina.
The fibrous membrane is formed by thearrangement of fibers, hard, tough and resilient, having an effect on the eye,and keeping the shape of the eye, as in the case of an egg shell. Fibrousmembrane can be divided into the cornea, the scleral, the angle and the scleralrim. Pigment film is also called the grape film, has the effect of nutrientintraocular arrangements and shading, from the front and back can be dividedinto the iris, ciliary body, the clue film three some. Iris base has pupil.
Intraocular containing water, lens andvitreous body. These three are some of the outer layers of the cornea, itconstitutes a refractive index system. The real water is colorless andtransparent liquid, with anterior chamber, after the room is about 0.15 ~0.3ml, it has the effect of nutrients and maintain intraocular pressure. Theiris is located behind the front lens, vitreous body, and with the suspensoryligament of the ciliary body contact is a flexible arrangement with lit.Vitreous body was colorless and transparent jelly, full of cavity behind thelens, with the refraction of light, the fixed effect of retina. Vitreous bodyand lens water, cornea and so on together constitute the eye's refractivestroma, but also on the retina and eye wall support effect, so that the retinaand the thread of the film. In trauma or surgery, once the seizure of vitreousloss, it is easy to form retinal detachment.
Refers to the bottom of the fundus as eyes,that is the most eyes inside the arrangement. It consists of the retina, theoptic nerve papilla, and the retinal vessels of the retina. If there is adisease in the eye, it will have a great impact on vision. Performance forreduced vision, visual distortion, discoloration, as large and small.
People's eyes inaddition to the eye wall and eye content, there are some attached to thedevice, they are the eyelids, conjunctiva, lacrimal device, eye muscles andeyes.
From the opticalpoint of view, the eyes can be seen as two systems: the cornea and the crystal.The base of each surface is located on the common axis, which is located on theoptical axis. The optic axis is generally in the retina at the base of thenasal cavity and slightly above the nasal side, uniform view of the skew, inthe horizontal direction of 4~5 degrees (a), and the straight direction of theskew is slightly greater than 1 degrees.
General in the eye (such as insectarthropod animal) that generally has a lot of simple facet, and attack animpression (more general impression is not imagined).
In manyvertebrates and some soft bodied animals, both eyes are projected onto thelight sensitive retinal imaging, where light is subjected to and converted intosignals and transmitted through the optic nerve to the brain. Both eyes arespherical, with lit sideways gelatinous substance, there is an aggregation withthe lens, and a general can control how much light into the eyes of the iris.
First,the word, it is a target and limit (province) constitute the word. We know thatour eyes have a distance constraint, too far or too close to see. With the eyesare the windows of the soul, and the passions of the people demonstrating,likes and dislikes, borrow to make up the meaning of speech sound. Besides, inorbit, park, two cross that has two eyes, there is a non sexual. Ancient mo (bydefault), which indicates that the binocular vision. That is: the eye issilent, can not speak, but a look to know. After the use of no (MU) sound, thatthe eyes are constantly blinking, when the time is not. Eyes is a single body,is the evolution of the image, but also can not completely express the meaningof the function of the eyes, there is no performance of the sight distance isbound, so made this fit word. Refer to the "Chinese character pass".Text is also with the times, as we know the nature of the deepening, willcontinue to attack the new Chinese characters, Chinese characters are the eraof.
I believe we all know how our eyesstructure is messy, so when in the use of our eyes to work, we must maintain asafe security function of eyes, optical laser eye protection glasses completelymeet the GJB1762-93 laser safety glasses, reflective absorption type, all-roundprotection of specific band the laser and light. For a variety of laserequipment. The visible light transmittance of more than 70%. The opticaldensity is above 5, (OD+5, OD+6), so I want to buy an eye protection when boundto understand its function
