Make your own sunglasses. Removable sun protection pad for glasses. Turning regular glasses into cat eyes
Summer is ahead. Sun, beach. Need to know how to choose Sunglasses .Although the beach season is still far away, the sun is already breaking through the thick clouds with its first timid, but nevertheless bright rays. And no matter what anyone says, you need to protect your eyes from the sun. Stop! Don't look for protection in the subway or market tent. That is, of course, you can hide from the sun there, but finding normal glasses that protect from harmful radiation is unlikely. There is a scientific explanation for this.
Everyone knows that glass (even transparent window glass) does not transmit ultraviolet radiation. With plastic the situation is completely different. Until recently, it was believed that it provides almost no protection to the eyes. That’s exactly how it was. But science did not stand still and a special coating was invented. As a result, light, comfortable, almost unbreakable glasses have become useful.
Unfortunately, it is completely in vain to look for this miracle in markets or metro stations. What hawkers offer us, as a rule, cannot truly protect against ultraviolet radiation. However, I'm wrong. Cute multi-colored pseudo-glasses save you from bright light... an electric light bulb. So, if you are fascinated by the sight of a red-hot tungsten coil, please take advantage of it. But no, no, no going outside.
Reducing the brightness of light, darkened plastic does not at all interfere with the passage of hard ultraviolet radiation. The deceived pupils dilate and let in much more dangerous rays than if you were without glasses at all. Therefore, it is much safer to buy eye clothing in optical stores. There, by the way, there should also be special equipment to check the protective ability of the lenses.
The right glasses also vary. According to their purpose, they are divided into three groups: comfortable, protective and special.
Comfortable ones are those that are needed for every day. It is best if the lenses are made of CR-39 plastic. Shading should not exceed 50%. Can be used photochromic lenses, popularly nicknamed “chameleons”. They change the degree of their shading depending on the weather and time of day. Gradient colored ones are also suitable: transparent at the bottom and dark at the top. As for colors, it is better to rely on tradition. Dark grey, brown or greenish glass is just what you need. Pinks and golden yellows are good for a cloudy day. But wearing blue or light blue is generally undesirable. These colors help dilate the pupils and make the lenses vulnerable.
As summer approaches, the question of purchasing sunglasses. This small accessory can not only provide you with protection from ultraviolet rays, but also add originality and sophistication to your style. And that’s why it’s better to choose glasses not at the counter, where you’re simply lost in their variety. We will try to tell you more about sunglasses, about what you may not have known until now.
Sunglasses Material
Material should be the primary criterion when choosing sunglasses because... health where more important than style or image. Glasses not only help protect your eyes from bright sunlight, but also block ultraviolet radiation (glasses with glass lenses only).
I would like to say right away that it is too small glasses(whether glass or plastic), although they will look stylish, will be a poor assistant in sun protection.
Traditionally, glass lenses are considered better: they not only provide good protection from ultraviolet radiation, but also the world will be less distorted than in plastic ones. In addition, glass is more scratch resistant. But here's the downside glass glasses, of course, their fragility remains, and they are heavier than plastic ones. Such glasses are not recommended for athletes, and especially children. There is a possibility that the glass will break and, if the circumstances go wrong, can damage your eyes.
High-quality plastic can be a good alternative for your glasses. To protect against harmful radiation during manufacturing, special additives are introduced into the plastic composition, and special coatings are applied to the finished lenses. Sunglasses made from this material are lighter and more practical. An unpleasant moment There may only be distortion of objects, but you can evaluate this quality directly by trying on glasses: straight lines should remain that way.
When choosing glasses (with glass lenses), you should pay attention to the markings of the glasses. “UV-A” and “UV-B” (ultraviolet) show, as a percentage, the degree of protection against ultraviolet rays, with type “B” being considered the most harmful. You can also see the designation “400 nm”, which indicates the maximum wavelength from which the glasses protect. If the number is less than four hundred, it means that some of the rays are still missed.
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 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.

Glasses are not only the main summer accessory, they protect our eyes from harmful radiation, reduce fatigue and harmoniously complement the image. If, of course, you choose them correctly.
website I decided to figure out how to choose glasses specifically for your face shape and how to distinguish good lenses from the bad ones. And at the end there is a bonus for you.
How to determine your face type
Take a washable marker, lipstick, soap or pencil. Stand in front of a mirror at arm's length. Without deviating, outline the contour of the face, starting from the chin and ending with the hairline. Take a step back and look at the resulting shape.
The goal is to visually lengthen the face, so choose dark-colored frames. They narrow the face and bring it closer to an oval. To balance your facial proportions, choose frames that are wider than they are tall.
Suitable for round shape faces:
- Pointed, rectangular, square glasses.
- "Cat" frames.
- Butterfly glasses.
- Glasses with a narrow bridge of the nose.
- "Aviators".
- "Wayfarers".
Not suitable for round face shape:
- Round glasses.
- Narrow frames.
- Glasses with sharply defined corners.
- Glasses in the form of geometric shapes.
- Color contact lenses.
- Eyebrow-covering glasses.
The main task is not to violate harmonious proportions faces, so avoid too massive glasses. It is better if the width of the frame is equal to the width of the face or slightly wider. Make sure that the top of the frame coincides with the eyebrow line.
Suitable for oval face shape:
- Frames of smooth shape: rectangular, oval, round.
- Butterfly glasses
- "Aviators".
- "Cat" frames.
Not suitable for oval face shape:
- Frames with sharp angles.
- Frames are too massive.
- Frames too wide.
- Narrow frames.
Rectangular or square sharp shapes will overload the face. Rounded frames will help visually balance and soften the proportions of the face.
Suitable for square shape faces:
- Big glasses.
- Glasses with frame widths equal to the width of your face.
- Glasses with colored frames.
- Oval, round, drop-shaped frames.
- Rimless glasses.
- "Cat" frames.
- "Aviators".
Not suitable for square face shape:
- Square frames with sharp corners.
- Small, narrow and petite.
- Glasses with frames wider than the face.
You should visually expand your face. Choose large, chunky glasses. Transparent glasses- with thin frames to match your skin tone.
Suitable for rectangular shape faces:
- Large frames.
- "Aviators" (with large frames).
- Round frames.
Not suitable for rectangular face shape:
- Narrow frames.
- Small frames.
- Bright colored frames.
The task is to balance top part face, making the lower one heavier. Massive ones will make the top even heavier, we don’t need that. Choose glasses whose width is equal to the width of your face, preferably teardrop-shaped. Aviators are perfect.
Suitable for heart-shaped faces:
- Rounded, round glasses.
- Small frames with a narrow bridge.
- Low set temples.
- "Aviators".
- "Wayfarers".
- Rimless glasses.
- Light and neutral color of glasses.
Not suitable for heart-shaped faces:
- Heavy and large frames.
- Acute forms.
- Eyebrow-covering glasses.
- Butterfly glasses, drop glasses.
- "Cat" frames.
- Frames with bright colors.
The main task is to expand the upper part of the face and divert attention from the lower part. Choose glasses with large frames and wide top part. The bottom of the glasses should not be square, sharp or have a clear line.
Suitable for triangular shape faces:
- Round glasses without bright decorations.
- "Aviators".
- “Cat” frames with light glass.
- Rimless glasses.
Not suitable for triangular face shape:
- “Cat” frames with dark glass.
- Square, rectangular frames.
- Narrow and small frames.
- Glasses with a square or pointed bottom.
Bonus: checking glasses for UV protection
Take a UV flashlight and shine it through the lens of your glasses at any fluorescent object. This could be a pen cap, headphones, a felt-tip pen or stickers. How better glasses filter out ultraviolet radiation, the less the object will glow.
Checking glasses for polarization
Polarized lenses filter out reflected light, reduce glare and reduce eye fatigue. It is very easy to identify glasses with a polarizing filter. Look at the surface with reflections. If the glasses have a filter, the glare will disappear.
If you turn the glasses, at a certain angle the glare will disappear and appear again.
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 who, for obvious reasons, cover the entire upper part of their face with a dark rectangle. 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.
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.
