Now there are a lot of eyeglass online guide, the basic process is the offline optical shop/hospital ophthalmic optometry, with the computer optometry single directly to the eye city "big kill special kill" or directly Taobao, fight Xi Xi one. Focus on a reasonable consumption.

But friends listen to spring Yujun a advice, in this environment of consumption downgrade, glasses or to master four points! Today, Spring Yujun invited Liu Bing, chief ophthalmologist of Beijing University of Technology Hospital, to teach friends how to choose a suitable pair of glasses:

Four important points to know about opticians

Professional optometry

This need not be said more, we all know that professional optometry must first determine the monocular diopter, do fog red and green sense cross column mirror detection, and then balance the eyes, need to take into account the eye position, take care of the adjustment.

These are not a computer optometry single can solve, so only with a single optometry glasses, in fact, is not responsible for themselves. Through the corresponding detection means, according to the step detection, it takes about half an hour to complete an optometry. Some professional optometrists are required to charge for optometry.

Good lens

There are many kinds of lenses, the refractive index of the lens, Abbe coefficient, wear resistance, radiation resistance, anti-pollution ability, spherical and aspherical surface have many differences; Lens design, coating quality is also very different, according to the degree of refraction and personality requirements, make different choices.

Spectacle frame

Also need to pick, good product material, anti-oxidation, anti-allergy ability, deep hinge insertion, withstand the hinge test, solid frame, long use time, no deformation, frame and special function of the lens to match. These are the main points of our selection of frames, you can ask the staff of the optical shop about the above aspects.

Fit out

Whether the center of the lens can be aligned with the center of the pupil, whether the position of the lens and the eye is reasonable, and whether the edge is clear and floating also determine whether a pair of glasses is beautiful and comfortable.

Pay attention to the above four aspects, you know how to do, where to go, how to choose glasses.

Eyewear care Tips

Take off your glasses with both hands

Taking off the glasses with both hands can avoid the deformation of the glasses due to the uneven force of taking off the glasses with one hand. Secondly, wear glasses can not be too tight or too loose, the distance between the two legs of the glasses and the curvature of the legs should be appropriate, such as the bend of the glasses foot just on the ear, can not be too tight. Also pay attention to the appropriate lens eye distance (the distance between the cornea and the lens), not too close or too far. Generally, the eyelashes can not sweep the lens, as close to the eye as possible.

When not in use, it should be placed in the mirror box

Many people put their glasses randomly after taking them off, so that the glasses are often damaged, and should be put into the glasses box as far as possible to avoid squeezing. Place the lens face up to avoid wear and tear. Glasses should not be placed in a high temperature and humid environment for a long time, such as sauna, car windshield, bathroom, kitchen, so as not to accelerate the aging of the lens and the deformation of the frame.

First clean the dust and then wipe

The surface of the lens is easy to be covered by dust, water vapor, grease, etc., at this time, after wearing the glasses, you will feel that the vision is blurred, and the clarity is significantly reduced. Should be cleaned in time to maintain the height of the lens clear. When cleaning the mirror, the dust of the lens should be washed (gently brushed), and then cleaned with a neutral detergent such as dishwashing liquid. It should be reminded that when wiping glasses, it is best to use a special glasses cloth to avoid wearing the lens.

Frames and lenses should be noted

The mirror body and foot should not be pulled or twisted at will, should be replaced in time when broken, the nose support is loose, and the frame deformation should be handled and repaired in time, so as to avoid the deviation of the optical center or astigmatism axis of the glasses, causing visual fatigue. If the width and narrowness of the mirror leg are inconsistent and the height is unbalanced, it may lead to changes in the optical parameters of the mirror, causing discomfort and other conditions.
