Make sunglasses. How to choose glasses that are perfect for your face type. Don't skimp on sunglasses
There are not many things in the world that have remained virtually unchanged since their invention. Glasses are one such item.
Glasses were apparently invented in Italy in the 13th century. The estimated year of invention is 1284, and Salvino D’Armate (Italian) is considered to be the creator of the first glasses, although there is no documentary evidence for this data. Since then, glasses have become a part of many people's lives. The production of glasses has changed significantly. So I began to wonder how they make glasses for vision now. For permission to film the production process, I turned to the management of the Chameleon company, who agreed to meet me and gave the go-ahead for filming...
Just as any theater begins with a hanger, so any production begins with a warehouse.
This is exactly what blanks for lenses look like, which after processing will take up space in the frame
Previously, mostly glass was used for lenses (in the first glasses they used quartz and crystal because they could not yet obtain high-quality glass), now high-quality plastic is increasingly used. Plastic is lighter, cheaper and has more processing capabilities
Now the choice of lenses is very large - there are tinted and gradient lenses, coated lenses, etc. and so on. For every taste and color
But let's return to the production chain. After you have chosen the frame for the lenses and the lenses themselves. The manufacturing process begins
The Dioptrimeter comes into play first.
Lensmeter Tomey TL-100 (Japan) allows you to measure any lens; the device records the refractive power of the glass and expresses it quantitatively - in diopters
In the process of high-precision scanning of the frame, absolutely all parameters are determined: shape, base curvature, as well as the profile of the bevel groove in the frame, which, in the end, is a decisive factor in calculating the size of the finished lens. Using the high-precision frame scanning feature, the finished lens after processing will perfectly fit the frame, without any additional “fitting”.
After scanning the frame, the master places the lens blank into the centering chamber, where it is completely automatic. The system will determine the optical center of the lens, its refraction, cylinder axis, progressive lens marking or bifocal segment. .
The outline of the scanned frame and the lens in the centering chamber are clearly visible on the monitor
After receiving all the necessary data, the lens is placed in a processing (turning) machine, which operates on the basis of an EAS cycle.
Thanks to this cycle, the machine automatically selects the clamping force of the lens and the force of its pressure on the wheels during the entire processing cycle.
Processing time is no more than 1 minute
and we receive a finished lens, machined to the size of the frame.
This is how glasses are made literally in 10-20 minutes. Most of the time is spent on choosing suitable frames and lenses because... The choice of these products is very, very large...
Have sharp eyesight.
Thank you for your attention. I hope you enjoyed it. I express my gratitude to the management of the Chameleon Optical Salons Chain company for the opportunity to conduct the shooting.
Glasses are not only a decoration, but also a necessity for many people with vision problems. Their most fragile parts are the arms, which often break. We present to your attention a method through which you can now easily make glasses at home.
Necessary materials
Dark veneer for frame (2 pieces 50x30)
Light veneer for interlayer (3 pieces 50x30)
Wooden block (approximately 50x30 cm)
Epoxy resin
Vise
Sandpaper
Spring clips (2 pieces)
Jigsaw
Varnish
If you look closely at the frame of the glasses, you will see that it is slightly curved. To make the frame look like this, you need to draw a slightly curved straight line on a wooden block and carefully divide it into two parts along the line using a saw. You will get two bars: one concave on one side, and the other convex. All these parts are well sanded and sealed with tape.
Make a frame from veneer. To do this, 3 light pieces of veneer are laid together one on top of the other, and dark ones on top and bottom.
All parts are well glued with epoxy resin.
Thus, the future frame will be layered.
To prevent the layered veneer from coming apart, you should place it in a bag and wrap it tightly with tape. Then lay the veneer in parts of the timber and clamp it in a vice. Allow to dry completely.
Excess glue should be removed and sanded sandpaper from all sides.
Place the old glasses frame against the veneer and secure with spring clips. It is necessary to trace all the contours of the glasses with a pencil.
Using a jigsaw, cut out a new frame along the pencil lines.
The holes into which the glasses will be inserted should be sanded.
The temples of the glasses can be made from any small wooden block, 1-1.5 cm thick. To do this, you need to trace the old temples with a pencil and cut along the contours with an electric jigsaw.
By personal fitting, determine the angle of inclination of the arms in relation to the frame of the glasses. Then mark with a pencil, draw a line and cut with a jigsaw.
It is necessary to make locks that will connect the temples and frame of the glasses. To do this, draw the convex parts of the lock on the arms and the holes for them on the frame. Using a hacksaw, carefully cut.
Then connect the arms to the frame.
Coat all wooden parts with varnish.
Sunglasses is not only a stylish accessory, but also an important wardrobe item that will save your eyes from UV rays. What qualities should such glasses have?
The first thing you need to pay attention to when purchasing is protection from UVA (wavelengths 320-400 nm) and UVB (wavelengths 290-320 nm). This information must be indicated on the glasses label. Two options are allowed: “UVA and UVB protection” or “UVA 400 protection”.
Do not buy glasses from unverified places. The sellers there will not be able to guarantee you protection. But don't rush to overpay for glasses popular brands: Even the most budget accessories have UVA and UVB protection.
The color of the lenses is of particular importance. The darkness must be at least 75%. It is best to choose yellow and orange lenses. Blue and purple are a dubious option. According to ophthalmologists, lenses of this color provide less protection. But it is worth noting that the fluctuations in indicators are not that great. Therefore, if you absolutely do not like warm glass sunny shades, feel free to take a different color.
By the way, if you wear contact lenses, then we can please you: most of them already include UVA and UVB filters.
Here are some more tips that will help you when choosing glasses.
- For driving, buy glasses with plastic lenses. In the event of an accident, they are less dangerous.
- Photochromic accessories are a great option for those who wear corrective glasses all the time. The lenses darken when exposed to sunlight. Therefore, in your room regular glasses, and in the sun - sun protection.
- Buy a special cloth for cleaning glass - do not use the edge of a T-shirt for this.

How to choose the right one sunglasses? The principle of http://site/ here is the same as when choosing any new thing you need - you should like glasses, be of high quality, be comfortable, have an adequate price, and make you even more attractive.
Depending on some factors (scarcity of funds, indifference to things, lack of taste...) these four criteria may be placed in a different order, or even decreased by a couple of units. However, the fourth point - “to make you even more attractive” should remain unchanged, or even move to first place. In the end, you can save up money, put up with small flaws in terms of comfort (well, you can’t sleep in them!), but you simply have to look 100% better in new sunglasses!
To make you understand that buying glasses is not a waste matter, I’ll tell you a story. , I urgently needed to buy myself sunglasses, because I drowned mine while swimming in the lake. Somehow I didn’t manage to get to the store, and so I had to look for glasses on sale, inexpensive ones, of course, since the hawker trade is focused on middle-class and lower-class goods.
As a seller, I liked a long and thin, like a pole, black man, who for some reason had the fewest buyers. Deciding to support his feeble trade, I quickly bargained for international language gestures quite nice glasses slightly elongated top edge forms that can turn any face into a dragonfly muzzle. Which is what ultimately happened.
For some reason, the fashionable dragonfly glasses that season looked on my thin and slightly elongated face like a saddle on a cow, and like a big saddle on a small cow. The first one I took with the new glasses reminded me of photographs of survivors plastic surgery women whose entire top part faces. You could just as easily buy ski goggles– these also left only the tip of the nose and lips free. But, unlike the ski ones, they also kept sliding down every minute, squeezing the nostrils, as in synchronized swimming.
This lesson cost me only a few dollars, but I remember it for a long time. You can’t make purchases on the run unless you plan to throw them in the first trash bin you come across. Smart people it's been run in for a long time necessary recommendations– what type of face is suitable for what glasses.
The size of glasses should also be measured against your build, since very large glasses are small face They look pretty awkward. However, the same as the other way around - small glasses on a wide face. Under no circumstances should they slide onto the tip of the nose or squeeze the bridge of the nose, leaving furrows that do not disappear for two hours.
I will not write a scientific treatise on this matter, and you do not need to study this problem as such. Just look at the pictures carefully and try to get the gist. This will be quite enough.
If this season you have not yet managed to purchase new sunglasses or managed to drown, lose or sit on them - take a look at the showcase of fashionable sunglasses. Surely, you can choose something suitable here.
Greetings, reader!
I present to your attention a review of the universal sun protection pad for glasses.
Life myopic person Siberia is full of insidious surprises and surprises.
It's summer, so let's look at summer tricks.
Actually, the problem is basically one... 
Often, while driving, neither a sun visor nor… a sun visor can help. Having inquired about the cost of optics sun lenses with diopters, I'm a little depressed. 
The price tag was quite high.
Of course, as an option, you can wear regular sunglasses (as I sometimes do) in combination with lenses. But it is not always convenient and accessible. Besides, I don't really like lenses, to be honest.
So I noticed this overlay on regular glasses. I remember once, in the early nineties, my father had similar ones. I ordered a couple for myself, classic and aviator. The classic arrived faster, so I’ll write about it. The parcel arrived for almost a month. Ordered 06/10/15, received in Barnaul 07/09/15
Needle in the egg, egg in the duck, duck in the hare, THE HARE IS SHOCKED!
In a bubble bag there is a plastic bag containing a case containing the subject.
No one is interested in a yellow bubble bag. He was almost instantly swallowed up by the urn. The plastic bag is also not something to admire.
The case for the subject looks like this. 
And here is the pad itself, I’ll call it for convenience, device
more types 
The mounting device for this device has a slightly monstrous appearance, rising above the bridge of the nose.
But
We don't chase style, functionality is important to us
This is what my glasses look like 
Let's try the device on glasses o_o
op 
A couple more types
Here you can see that part of the lens is not blocked from below. But this is an insignificant point. 
Trying on me
Standard view 
I need your clothes and motorcycle 
If you need to improve your visibility, for example in a dark room, you don’t have to remove the device from your glasses. You can, for example, bend them at an angle of 90 degrees, like a visor. The view is funny... 
... or even bend it 180 degrees 
For what? The devil knows, there’s probably no need, but there’s such a possibility!
The device passed the simplest polarization test. When you look through it at the smartphone screen, the colors are distorted; when you turn the device 90 degrees, the picture on the smartphone completely fades.
The device was purchased at affordable price, "for testing." Overall, everything is fine. The “aviators” coming to me have fastening devices that are much more aesthetically pleasing and do not stick out so high.
Thank you for your attention!
PS: Dear readers. Thanks for the advice and warnings, but...
As I indicated above, I have contact lenses (on different cases life). I have normal sunglasses.
I don't suffer or suffer. Buying this device is conscious choice, based on a combination of factors present to one degree or another in my life.
I don't intend to do laser correction vision, for a number of reasons that are of no interest to anyone but me.
I performed the only currently available test for the presence of polarization in front of the monitor, the pad showed the same effect as ordinary sunglasses. I can’t tell you for sure about UV400, please tell me how to check? I will be grateful.
The price for lenses for glasses with a darkening effect, or simply dark lenses combined with all their parameters (astigmatics and other differences) has made them inaccessible to me for now. I have good lenses with everyday glasses, this is enough.
The device does not create additional load on the bridge of the nose. He is almost weightless.
The second device ordered has much more modest mounting hardware and larger size, covering the entire lens regular glasses. If I like it more, I’ll order more yellow ones for evening and night driving. Gov Gore-xenon, headlights that are not adjusted according to regulations and agro-tuning of fog lights/dRLs shining in all directions is sometimes very annoying when driving in dark time days.
