Wearing glasses for a long time, it will inevitably fall on the dust, not to mention the autumn and winter smog-prone cities. Most people are probably a reaction to the Ha breath glasses, glasses cloth or even lift out the sleeves began to wipe. But you know what, optical shop not send glasses cloth used to wipe glasses.
Glasses cloth can not wipe glasses? So many white wipe
Why can not wipe glasses cloth glasses?
Glasses cloth - we are talking about the kind of general store glasses gift, not rubbing cloth SLR camera - low cost, the main role is merely cushion wrapped glasses, glasses case and prevent friction to prevent the collision of hard or sharp scratch material damage. (A talking!) Is used to package the glasses.
Cheap glasses fiber cloth gap larger over time will harbors many a lot of dust. Bristol case higher surface hardness dust (for example, fine sand ah, quartz hardness of 7) will scratch the lens, so the use of such glasses cloth wiping glasses would be counterproductive, the more friction the more blurred. Moreover, had regularly wash cloth, too much trouble.
Glasses before the general use of optical glass lenses, wear resistance. But now the vast majority of spectacle lenses are resin lenses, poor abrasion resistance, prone to scratches. Media experiment that under the microscope, scratch the lens surface is divided into two kinds, one is due to scratches gravel produced, shallow and small, the wearer is not easy to the other is designated by the larger gravel generated marks, deep and rough periphery, at the center of the area will affect the vision.
Dirty glasses, how do?
The most convenient way is this:
Ha ha ha, say down to business.
Rinse - Do not use hot water. Water can wash away the dust in general.
But for the oil adhered to the surface of the plated layer, fingerprint stains, we need to use glasses cleaning agent. The detergent for washing dishes and other non-delicate of items, some of which contained the chemical composition of the coating layer has a strong corrosive effect, over time, will penetrate into the interior of the reflective film, will lead plated layer part shampoo, shower gel will leave a layer of grease, wash clean. So usually with water or a special cleaning fluid cleaning glasses glasses better.
After the lens is cleaned and then washed away with a calm water. What, there are drops of water ah? I focus on do not say! (I am a Virgo you bite me ah) vertical lens (you sense what ah), and let the water flow from the lens evenly over both sides of the slow movement of the lens, the lens and almost parallel to the water column, "scanning" rinse lenses. Using this technique, the lens is generally not any residual water droplets or fingerprints, so it will not dry when the secondary pollution in the lens, just after cleaning in the vicinity of the frame to erase the remaining water droplets. Probably the whole 20-30 seconds.
No successful students like him to try several times, learn to control the size of the water!
Current optical shops generally provide free cleaning services. But the store wash water usually pay only a few change, even only once a day it may not be enough health, depending on how seriously each store conditional, then you can buy a small ultrasonic cleaning machine. After all, a good lens to a few hundred pieces. Prices of ultrasonic cleaning machine more than one hundred to several hundred dollars, are sold on a treasure, I do not advertise it. Specific instructions can read the instructions, but I want to remind you, man-made crystal mosaic frames can not use ultrasonic cleaning, more often may cause fall off. The surface paint as much as possible not to use, so as not to speed up the peeling paint.
If going out is not convenient, it recommends a one-time, special paper to wipe the lens. Monolithic installation, easy to carry, do not wear lenses, camera lenses can also be used. You can still ask for a universal treasure, Keywords: glasses paper. No difference, about fifty cents a.
To be so good, I myself have been moved.
