Abstract: "American things are so cheap!" It seems that people who say this must not buy glasses in the United States. You know after buy glasses here, things in America are not so cheap.

First of all, glasses in the United States must be optometry, or you have an optometry sheet, effective within 2 years. Generally, optometry is free in China's optical shops, but in the United States, optometry and matching are separated. There are optometrists in ophthalmic clinics and large optical industry, and the cost is generally about 40-60 dollars.

After optometry, we have to choose the frame and lens ourselves.The price depends on different glasses stores and brands. Of course, insurance is also very important. Some optician's insurance can cover part of it, which is more cost-effective. However, each optician's insurance is different, so it's still necessary to find out. Because there is no insurance, the price difference will be large.

If you want to choose the cheapest glasses, Costco is basically the first choice.

There are optometrists in every Costco, but this doctor is not a Costco employee. He just signed an agreement with Costco to open the outpatient service in Costco. Optometry technology also varies from store to store. You can also have optometry in other places, just take the doctor's prescription. Costco's glasses are basically brand names, such as Fendi, Armani, Burberry, and coach and guess. The price is basically between 50-150, most of which are about 90. Compared with other glasses stores, it's quite cheap. Costco receives VSP insurance. It can cover part of it, and often has discount. And it's said that a new one can be replaced free of charge if it's damaged within one year (the after-sales service is really good!). Costco can also be fitted with contact lenses. In addition, Walmart and target will also have cheaper glasses.

In addition to Costco, the glasses in many Chinese opticians are not too expensive.

We recommend fuliming glasses Co., Ltd.

Guangming glasses store

In addition, you can also buy glasses on the Internet, and there is muukal, a website that specializes in selling glasses. Of course, you also need an optometry sheet to buy glasses on the Internet.

If you don't have insurance, or you think the glasses here are too expensive, it's recommended to go back to China and find some better ones. The cost performance ratio may not be lower than that here.

Sunglasses are not only  cool , but also a must-have item. In the face of all kinds of sunglasses, are you tangled? Style, in fact, is only the last consideration. How to choose, there is some knowledge.

In summer, the sun is dazzling. Invisible ultraviolet light makes people have nowhere to hide. Most people know that excessive ultraviolet radiation can damage the skin. However, that many people didn't expect is that UV can also damage our eyes, and even cause cataracts, burns and even cancer in serious cases.

UV damage to eyes

According to the wavelength, UV can be roughly divided into UVA, UVB and UVC. Among them, UVC can only reach the ozone layer, and UVA and UVB can penetrate the ozone layer, directly to the eyes.

UVB can shine on the lens of the eye, but UBA can shine further to the retina of the eye.

The main damage to the eyes caused by excessive ultraviolet radiation is cataract, macular degeneration, skin lesions around the eyes and even cancer.

Cataracts

Cataracts are the main cause of vision loss or blindness in people over 40 years old. The crystal of normal eyes is clear. If the crystal becomes turbid (right side of the figure below), the light cannot be focused, resulting in blurred vision, or even completely invisible in serious cases.

About 20% of cataracts are caused by excessive ultraviolet radiation.

Here's what cataracts look like:

Macular degeneration

UVA is more penetrating and can reach the retina of the eye, causing damage. Macula is a place where light sensitive nerves gather to help transmit images seen by the eyes to the brain. As you age, there are some degenerative changes in the macula (right side of the image below), such as deformation and bleeding, which can be accelerated by excessive UV light.

Skin cancer

Excessive UV exposure also increases the risk of skin cancer, especially UVB.

Therefore, sunglasses are not only fashionable, but also necessary for eye health.

The first factors to consider when choosing sunglasses are:

How to protect our eyes as much as possible?

The ability to block ultraviolet light

Sunglasses with high shielding UVA and UVB are preferred

Although sunglasses, to some extent, can protect against ultraviolet rays, but to choose sunglasses that can shield most UVA and UVB ultraviolet rays, shield at least 99% UVB and UVA.

Be sure to look carefully at the UV shielding on the label. Those who don't indicate UV protection should not buy Sunglasses from reliable stores. Besides, a wide brimmed hat is a good choice

The color of lenses is exquisite

The color of the lens itself has nothing to do with its ability to protect against ultraviolet rays, not that the darker the lens, the better. However, the color of the lens will affect the contrast between the color we see and the background color. So, in different situations, for different people, the choice is not the same.

Gray lenses reduce light intensity and do not affect contrast or distorted color. Brown lenses block some blue light, enhance contrast, suitable for snow sports, also suitable for bright light and open background. Amber / yellow lenses enhance contrast, because they block most or all of the blue light, so they are popular in hunting. Hunters can easily see their targets in the sky, and they are good for snow sports. However, they are bad for any situation that requires color recognition, such as driving a car.

Patients with macular degeneration or diabetic retinopathy may consider amber or brown lenses. These colors enhance contrast and help patients see better.

Red / orange lenses are suitable for snow sports, but only for cloudy days. Violet lenses are suitable for clay targets on a green background. Bronze Sunglasses are more suitable for golf. Blue and green sunglasses are more suitable for tennis.

Do you want a polarizer?

First of all, polarizers and UV protection are totally different things. Although many sunglasses are polarized lenses, the polarizers themselves cannot shield the ultraviolet rays.

In short, all kinds of objects in nature will reflect sunlight. The working principle of polarizer is to reduce the direct light to the eyes from all angles by applying special chemicals on the lenses.

Advantages of polarized lenses include:

Clearer field of vision, especially when the light is bright, enhance contrast and reduce color distortion, reduce glare and reflection, and reduce eye fatigue

These advantages make polarized lenses very suitable for sunglasses, especially in outdoor activities.

Here's a comparison: no polarizer (left) and polarizer (right). Polarizer reduces glare caused by reflection from water surface and increases contrast.

Polarizing lenses also have some disadvantages and are not suitable for the following situations:

Look at the LCD screen. It is difficult to see LCD screen with polarizer. If you need to look at the instrument cluster or screen, the polarizer is not the best choice. Flying in low light or at night

How to know if your sunglasses are polarizers?

Just try. Choose a reflective plane, the polarizer will reduce the glare caused by the plane reflected light, increase the contrast, and see more clearly. Then, look at the LCD screen. The polarizer will make the screen dark and hard to see.

Face shape and sunglasses

Finally, we can talk about fashion. Let's take a look at some sunglasses. Various styles and styles are shown in the figure below.

Then, choose the right shape for your sunglasses based on your face shape. The following are recommended sunglasses for different face types:

Oval face: it can be called "perfect face shape" and can wear glasses of any style. Just avoid the frame being too thick or too thin.

Square face: this type of face has obvious edges and contours. You can choose round glasses to balance it and make sure the frame is not too thick. Try to choose wide sunglasses and avoid using rectangular glasses.

Round face: full cheeks, round chin. Choose a polygon or square Sunglasses with angle design to balance a little. Thicker frames can also be harnessed.

Long face: choose large lenses and polygonal frame to decorate. Consider the popular retro glasses and sports glasses.

Flat face: choose a darker lens and frame to highlight the face contour. Bright colors can also make expressions more vivid!

No matter which one you choose, make sure the sunglasses are suitable and comfortable to wear.

Make sure that the sides of the head are not pinched. The weight of the glasses should be evenly distributed between the ears and nose. Your eyelashes should not touch the frame or lenses. The glasses should be right on the bridge of the nose and the ears, without leaning to one side.

Driving Sunglasses

As we grow older, our pupils grow larger and more sensitive to light. Direct sunlight is often too harsh. In order to see better when driving, try to choose polarized lenses, which are most suitable for reducing glare. This is particularly important if you have had an operation, such as LASIK.

In addition, choose brown, gray, or yellow lenses to reduce color distortion.

Do children need sunglasses?

UVA and UVB radiation damage is cumulative over the course of a lifetime, the U.S. vision Commission warned, so let children know the importance of wearing sunglasses as early as possible. If you are outdoors for a long time, the six-month-old child will start to protect his eyes.

Prescription glasses

Prescription glasses, especially those with polycarbonate lenses, often have some built-in UV protection. Lenses that automatically darken when outdoors usually prevent UV and glare. In addition, optometrists can help us choose the right sunglasses.

Conclusion

It's important to protect your eyes. Sunglasses are essential. The first choice is to shield 99% of UVA and UVB functions, followed by color and style. Polarizers are a good choice for outdoor activities and driving. Children need it, too.

Choose a cool sunglasses, anti UV plus polarized light, enjoy the sun!

How to choose sunglasses and earrings with different face shapes?

Sunglasses and earrings are two ornaments that can greatly decorate the face, but it's a disaster if you choose them wrong. Today, let's see how to choose sunglasses and earrings for different face types!

Round face

Features: short face, round jaw angle.

Key point: because the face is more round, we should avoid round ornaments. (because the ornaments with round face will be more round)

Therefore, in the selection of sunglasses, the round face is suitable for the sunglasses with edges and corners. It can remove too much smoothness and modify the facial lines, such as Pilot Sunglasses and overage sunglasses.

As well as the line slants the sharp Cat Eye Sunglasses and the square glasses.

Earrings are said to avoid round ornaments, so the first demining is round earrings. The long strip earrings are recommended. The long strip earrings can lengthen the facial line, making the face look less round.

Geometric lines are also suitable for round faces.

And this smaller model.

Square face

Features: large jaw angle, clear water chestnut angle.

Key point: due to the sharp edges and corners of the face, it is necessary to avoid geometric categories, especially square ornaments.

Suitable sunglasses, of course, are more mellow styles. For example, the round frame mirror can well decorate the edges and corners of the face, making it softer.

There are also cat's Eye Sunglasses, because they are wide on the top and narrow on the bottom, which can move the center of gravity of the face upward, so they are also suitable for square faces.

Earrings

As a matter of fact, square face earrings are not suitable for angular geometry.

It is more suitable for circular, elliptical and so on.

The length of earrings must be longer than the mandibular angle, so as not to increase the visual width of the mandibular angle, otherwise it will appear wider face.

Long face

Features: the width of forehead, zygoma and mandible are the same, but the width of face is less than two-thirds of the length of face.

Suitable Sunglasses: in fact, the long face is not suitable for wearing sunglasses, but if you must wear them, you must choose the oversize type with large and wide lenses to widen the horizontal proportion of vision. For example, this kind of one piece sunglasses, as well as the oversize version of round frame sunglasses and Pilot Sunglasses.

Earrings

In the choice of earrings, of course, it is necessary to avoid the long earrings and the longer face

Which one is suitable? My answer is: horizontal design earrings and exaggerated earrings. Because the horizontal earrings can widen the horizontal distance of the face and make the face look shorter.

Because of its large size, exaggerated earrings also play an obvious role in extending the horizontal distance.

This year's Round Earrings with exaggerated pearls are particularly popular

Triangular face

Features: narrow upper and wide lower, pear shaped face, Sunken Temple.

This kind of face has a lot of bugs, which is narrow at the top and wide at the bottom, so it is easy to appear big and bulky.

Suitable sunglasses are: caring type, wide cat's eye type

Cat's eye type sunglasses, which are obviously wide at the top and narrow at the bottom, are just the opposite of pear shaped face, so they can well decorate the temple part.

Love type sunglasses are also wide at the top and narrow at the bottom. Although they are not very common, they are also made of pear shaped face paper.

Earrings / of course, it is also necessary to choose the inverted triangle type earrings, that is, the upper, lower and smaller types of earrings.

To avoid this small up and down heavy style, or it will appear that the lower part of the face is wider

Heart face & oval face

I don't need to say more about the face shape that God cares for. It's basically suitable.

Well, that's all for today's selection of sunglasses and earrings. The fairies will take their seats according to their face shape. I hope you can buy satisfactory sunglasses and Earrings!

Fashion clothes and glasses are always closely linked. Glasses have become one of the necessities of life today. So, how to match glasses with clothes?

1、 Harmonious type: glasses color and clothing color are unified in one tone. If the clothing is red tone, glasses will choose the color close to red: clothing is white tone, glasses will choose the color close to white, etc.

2、 Contrast type: the color of glasses and clothing form a strong contrast. If the color of clothing is cold, the color of glasses is warm, or both, such as clothing color

is red, the glasses are blue: if the dress is purple, the glasses are yellow, etc.

3、 Embellishment type: use eye-catching glasses color to embellish large area and large volume clothing color matching, playing the effect of a little red in the green cluster. In summer, because of the difficult heat often gives people the feeling of restlessness and fatigue, due to the psychological impact, if glasses are not properly worn, it is easy to give people redundant burden. Therefore, in summer, matching glasses should be eye-catching rather than dazzling.

For example, the pink and gray stripes, with the red novel  frame, add a volume of air while showing a relaxed temperament. In winter, with the contrast of warm red headscarf and dark hair, if you put on the  frame of the same color to match each other, you are the embodiment of popularity and personality.

Hi, this is muukaloptical!

Nowadays, wearing glasses is not only the need of myopic friends, but a must for a lot of fashionable people. However, do you really know what kind of glasses are suitable for you? Hopefully, with today's post, you can get some ideas.

Buy glasses to suit yourself, this depends on the face shape! Most tutorials on the Internet are divided into seven or eight types, not easy to distinguish, here, we will divide into three types, round face, square face and melon seed face, more image specific, easier to distinguish.

Small round face, wearing round glasses very cute. But if fat people wear, it will look a little bit oily, and not very suitable for toad glasses, or square glasses.

Men with square faces don't fit into a square, but rather round and aviator glasses. The melon seed face is more suitable for aviator glasses and square glasses.

So, let's take a look at how the male models match their glasses.

Seth Patrick

Patrick, a muscular male model with a melon seed face and a pilot, looks more masculine. The aviator's large lenses also match the size of the larger man, while his is a bit like a windshield, cool and stylish.

Of course, Patrick is also good for square glasses.

Gerard sabe

Sabe's face is square, so a pair of round glasses is perfect for him. Can increase the overall fall broad feeling.

Of course, a square face also works well with aviator glasses, which visually shorten the length of the face and are ideal for a rectangular shape.

Also round glasses, metal material more retro, and plastic material more fashion, trend.

Sometimes, we can also wear a hat matching glasses. The hat can change the shape of the face and can be matched with the glasses to create different styles.

Fisherman hat with black and white cat eye glasses, suitable for all kinds of skin, except square face, others can be so built, clothes and trousers can be  casual.

A baseball cap with round glasses works well with white and yellow skin, not black. Match like this, suit square face more.

Finally, for this group, a red knit cap with green square glasses is ideal for oval and round faces. A red hat can be worn with green glasses or a black one, and a black skin can be worn this way.

Of course, introduced to everybody so much, more still need more collocation, ability knows the design that suits oneself truly and color.
