How sunglasses are made. Sunglasses, how to make the right choice. Suitable for oval face shape
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...

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.
I became concerned about protecting my eyes from harsh high-altitude ultraviolet radiation in the Himalayas back in the spring. The problem is that I wear prescription glasses all the time. I had to read a bunch of thematic forums before I finally made my choice. And there was plenty to choose from. I tried to collect all the options for eye protection from the sun for people with glasses.
1. Contact lenses and regular lenses Sunglasses
Pros:
- You feel more comfortable with lenses than with glasses. And you can buy any UV400 glasses, even the most inexpensive ones (500-700 rubles). You can buy a set of ephemera for 1,500 rubles and not have to worry about liquids. I put it on in the morning and threw it away in the evening. 30 pieces is enough for a month.
- If you have never worn lenses before (like me), then they can become a bit of a problem.
- Eyes in lenses dry out, especially on high altitudes- You need to have eye drops with you.
- The liquid in which the lenses are located can freeze at sub-zero temperatures and therefore they should always be kept close to the body.
2. Your glasses and ski mask on top
Pros:
Minuses:- Finding a special mask for people with glasses is not so easy.
- In any case, the mask will touch the glasses and cause inconvenience, pulling them off the right place On the nose.
- The glasses under the mask may start to sweat.
True, there is also an option with diopter inserts in the mask and it seems to me quite successful.
3. Your own glasses and regular sunglasses on top
Pros:
- Just as you were wearing your favorite glasses, you will remain wearing them.
- A pyramid of glasses on your nose is another pleasure.
- In any case, sunglasses will not fit tightly to your face and there is a risk of “exposing” your eyes to side rays and rays reflected from the snow.
4. Ordinary sunglasses with custom-made diopter lenses with UV coating or photochromes (“chameleon”) inserted into the optics.
Pros:
- It would be the coolest option, if not for the minus.
- One and the most important is the difficulty of making special sports lenses.
| Fig.1. Regular glasses. | Fig.2. Sports glasses. |
If you insert regular lenses into a sports frame, you will not be able to wear such glasses for a long time - you will feel that you cannot put your eyes together. In general, not a single optician in Ulyanovsk agreed to make such glasses for me.
5. “Straight” sunglasses with leather curtains
A cool option that is actively discussed on the forums. Standard: numerous models of the company Julbo.
There is only one minus: the price. For the glasses themselves without diopters you will pay from 6,000 rubles, plus about 4,000 rubles for inserting lenses with diopters. But, if you plan to use them more than once, this is a worthy option.
6. Welder glasses
The option of inexpensive welder's glasses with inserted photochromic diopter lenses is often discussed on forums.
Pros:
- They run tightly around their face, closing their eyes from rays from any direction.
- Have ventilation, preventing glass fogging
The disadvantages of this option surfaced when receiving points. Because of the flexible bridge, the glasses bent and caught the effect that I described in paragraph 4. It was impossible to look at the world for a long time in such glasses. I had to be smart to minimize the angle of curvature of the frames by placing a piece of foam rubber where they adjoin the temples. Now it seems to be tolerable. Let's see.
7. Clip-ons for glasses
Almost a week before this post, I learned about “clip-ons” - special overlays for regular glasses. The clip-on is attached to the glasses using a clip and allows the dark glasses to tilt up if necessary.
Pros:
- Ease of use and versatility
- Low price (500 rubles)
- Glasses still do not protect against side rays.
I ordered clip-ons so that I would have an option for the hot tropical climate of Nepal. It would be unwise to start a route wearing welding glasses in 30-degree heat. Besides, I won't scare many people on the track by wearing them.
These clip-ons have a polarizing effect and I will be happy to use them in ordinary life. For example, driving a car.
Sunglasses are 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. That's why you wear regular glasses indoors and sunglasses in the sun.
- Buy a special cloth for cleaning glass - do not use the edge of a T-shirt for this.

It's hard to find a person who doesn't have a pair of glasses at home, at least dark ones. Many of them gather dust in drawers and are not worn by their owners due to the purchase of new models. Don’t rush to throw away your “old” friends, because even ordinary glasses can be decorated using the simplest and most inexpensive tools and materials. In this way, you can update a worn-out frame that has served you faithfully for several years, or (an option for the brave) make the glasses you just bought unique.
So, we present to you 10 ideas for decorating glasses!
Regular glasses + two-color polish
You will need:
Nail polish in two colors;
- narrow masking tape;
1. Use a strip of masking tape to separate the half of the glasses that will be painted a different color.
2. Apply varnish to one half of the first color. Leave for 20 minutes.
3. Remove a strip of masking tape and varnish the other half of the glasses.
Turning regular glasses into cat eyes
Or you can make glasses like JLo by gluing silver sparkling “ears”:
Beaded glasses
You will need:
Beads;
- glue.
Glasses decorated with beads
You will need:
Half beads (you can buy them in stores that sell everything for creativity);
- glue.
"Friday" glasses with sparkles
You will need:
Sequins (creativity stores will tell you what they are) and sparkles;
- glue;
- parchment for baking;
- pencil.
1. Draw the shape of the frame on baking paper. Apply glue generously and sprinkle with glitter. Leave it for a while.
2. Cut out a glitter frame from baking paper.
3. Glue the paper frame onto the regular one.
Happy Friday!
Glasses with buttons
You will need:
- glue;
- buttons.
Carefully glue the buttons different sizes on the frame.
Glasses decorated with flowers
You will need:
Glue;
- paper or fabric flowers.
Glue flowers into the corner of the frame, just don’t overdo it with the number of flowers. These glasses will be a great addition to a light summer dress.
Glamor glasses
You will need:
Glasses with removable lenses;
- lace;
- a thread of sequins;
- glue;
- golden ceramic paint (can be replaced with nail polish).
1. Cover the temples of the glasses with a thread of sequins. It is better to take glue that does not harden instantly. Otherwise, the slightest mistake can ruin your glasses.
2. We cut out a square of lace that will be slightly larger than the lens, so that there is fabric left for the hem.
3. We take the glass out of the frame and apply glue along its contour. Glue the lace, tucking it inward. We insert the glass into the frame and trim the lace from the inside.
4. Apply stripes and dots to the frame with gold paint.
Glasses with bright temples
You will need:
Self-adhesive or regular colored paper;
- glue (if the paper is regular);
- scissors.
Draw the frame of the glasses on paper and cut it out. Carefully place it on the temple of the glasses, trim if necessary, and glue.
Using this method, you can not only decorate your glasses, but also hide some frame defects.
Spiked glasses
These glasses look very cool, and the cost of making them is minimal.
You will need:
Glue;
- tips from ordinary ballpoint pens;
- rhinestones (optional).
Carefully glue the pen tips onto the frame. You can additionally decorate your glasses with rhinestones in the corners of the glasses.
