After a series of processes, although the scrap rate was quite high, six pairs of lenses were successfully made, according to Professor Liu's request: after leaving one pair in the laboratory, Wang Zhengguo left with the remaining lenses.

After the two finished working overtime, it was already one o'clock in the morning when they returned to the dormitory, and they lay down and slept for a few hours, and got up early in the morning to go out with the lenses.

Carefully wrap the lenses, after saying hello, go out and ride a bicycle to Lao Zhang's shop, even before breakfast has time to eat, the road is also galloping, and with the bicycle flow of Shudu office workers, rolling forward.

In the 80s, although the road surface of Shudu was not as spacious as it was 30 years later, because there was no private car ownership in the country 30 years later, and there were not even a few cars on the road, it was easy to have a traffic jam, and the smooth traffic made Wang Zhengguo's cycling speed not much slower than that of driving in the city 30 years later.

Riding the car to the door of Shudu to store it, Wang Zhengguo was a little hungry, but there was no breakfast shop that could be seen everywhere after 30 years, at this time people had not let go of their courage, Wang Zhengguo naturally had no choice, so he could only go to Lao Zhang's shop hungry helplessly.

It's quite early to open the door, the old people generally get up very early after they get old, sleep lazy or something, this only exists in the young group, as long as the elderly do not lose sleep, it is a blessing.

As soon as I packed up my things and opened the shop, I saw that Wang Zhengguo had come. This early in the morning came in a hurry, and smiling, there must be something good, and then I didn't follow anyone else behind me, so obviously I didn't come to send an apprenticeship to myself, so I don't have to guess to know that it was to send lenses.

Thinking of this, Lao Zhang also temporarily put down the broom in his hand, quickly packed the operating table, put on glasses and gloves, and stood up and waved to Wang Zhengguo.

"Comrade Xiao Wang, you came to me so early this morning, you must have brought good things, then take them out quickly, I will also see what the quality of the lenses you said, in our country, it is the first time I have heard of the production of sunglasses. ”

I heard Lao Zhang say that he wanted to take out the lenses quickly, and then he found that although this Lao Zhang was a little old, his brain was quite bright, and he could see at a glance what he brought today.

After entering the shop, I dragged the bench next to me to the console, sat down, and then took the satchel off my neck, placed it firmly on the table, and opened it.

The lenses brought out from the optical laboratory are still somewhat packaged, so after taking out a cardboard box from the satchel, there are ten lenses neatly placed inside, each wrapped in cotton cloth, and also matched with the corresponding number, so that it will never be confused.

Take out a small package, carefully peel the lenses out of it, and after confirming that there is no problem, then push it in front of Lao Zhang together with the flannel cloth that wraps the lenses.

"This is the lens I brought today, you can see how it is, as long as you think there is no problem, I can go back and continue to optimize the process design, and strive to be put into mass production as soon as possible, which is also the highest technical level I can do at present, and then further want to make real polarized sunglasses, it may take a certain amount of time and technical accumulation." ”

Lao Zhang had seen the effect of the toad mirror before, and he would definitely be able to see the difference between the lenses at a glance later, so it was better to put the problems out first, so as not to say that the technical level of the lenses he brought was poor, how embarrassing it sounded, so it was better to talk about it here first.

Regarding the question of whether the lenses are good or not, Wang Zhengguo probably mentioned it, but it is still up to Lao Zhang to judge it himself, he took the lens in his hand and roughly weighed it, and the whole person came to the spirit at once, the weight of this thing is too light and weird, it shouldn't be!

I didn't have time to pay attention to the others, immediately took out the toad mirror in the cabinet, and compared the weight with each other, this gap was reflected at once, compared to the heavy feeling of the toad mirror, the weight of this lens is almost negligible, this lens is simply divine!

He put down the toad mirror in his left hand, held the lens with both hands and studied it carefully, at this time he had long forgotten that there was someone next to him, and looked at this piece of floating light red lens, I can only say that this thing is really exquisite, and it can still make the lens so light.

Feeling the various differences of this lens, and as if I had discovered something new, after carefully putting down the lens, I quickly took off my gloves and touched the lens directly with my hand, and immediately found that this touch gap is too big, and it is definitely a subversive new material!

After feeling it for a long time, he carefully put down the lens in his hand, and then looked at Wang Zhengguo, who was sitting next to him and had not spoken, he now has a lot of questions, and he must get answers from here: "This Xidong is very different, compared with ordinary lenses, it is not made of the same material at all." ”

To say that Lao Zhang will have such a strange expression and action, in fact, it is not surprising, PMMA resin lenses are in the sixties and seventies in foreign large-scale investment in the consumer glasses market, at that time Lao Zhang has been living in seclusion here, may know that foreign countries have used new lens materials, plus the domestic glasses industry has not made any achievements in this regard, now after seeing the shock, it is very normal.

In fact, not to mention that Lao Zhang will be shocked when he sees it, as long as he takes this lens to any optical store in China now, there will be at least eight stores out of ten stores that will not recognize the origin of this lens, which is caused by the current domestic environment, and no one is to blame.

"That's right, it's made of a resin-based material, and to put it bluntly, it's made of plastic, so when you pick it up, you don't feel like it's fluffy when you pick it up, and it doesn't have the cold feeling of traditional silicate lenses. ”

Wang Zhengguo, who was sitting on the side, briefly introduced the situation of PMMA lenses, and also made a series of answers to Lao Zhang's reaction just now.

This answer is already very straightforward, and it also makes Lao Zhang even more shocked, he can see the extraordinary nature of this lens material, but he never expected that it is actually made of plastic, to say that this plastic can be used to make lenses? and can be made so transparent, smooth, it really subverts his inherent impression of plastic.

Although he still couldn't digest the news of making lenses from plastic for a while, it didn't stop him from continuing to judge this lens and make it from new materials, which made him more concerned about the performance of the lens in all aspects.

Picking up the lenses again, this time I had a little bottom in my heart, and with a strong sense of curiosity, I began to comprehensively check all aspects. His first reaction was to see how the light transmission effect was, and he held the lens in front of his eyes, and saw a faint red color in front of his eyes, which was not surprising, and he knew that this was a deliberate effect of the lens.
