How much do regular resin sunglasses cost

Ranging from tens to hundreds of dollars.

I'm buying one for 100 this year. Don't bargain, the above said 10 yuan, what kind of eyes is that,

People in the 30s are not necessarily generational, outdated,!

The bad ones are a few dozen yuan, and the good ones are hundreds to thousands.

Nowadays, there are merchants who make at least half of the price.

This is too general, there are many kinds of plastic lenses, many brands, and different functions. **Of course, there are a lot of differences, from tens of yuan to tens of thousands! The general resin and coated lenses cost more than 100 yuan a pair! If you have any questions, you can contact us.

Why are the lenses fluffy after only wearing a pair of hundreds or thousands of dollars for a pair of plastic lenses? Experts point out that cleaning plastic lenses should be washed rather than wiped.

Spectacle lenses are generally nothing more than glass lenses and optical plastic lenses. The former has high hardness and good wear resistance, and the general quality and various parameters will not change over time, but glass lenses are slightly inferior to plastic lenses in terms of impact resistance and weight. The latter is thin and lightweight, and the impact resistance is better than that of glass sheets, but the surface hardness is lower and it is more susceptible to abrasions.

In order to expand the market of plastic lenses, some manufacturers and sales manufacturers have successively launched resin lenses with coating, hardening, and ultra-slippery processes in recent years, but they still cannot fundamentally change the "delicate" characteristics of the texture of resin lenses. Therefore, to prevent the resin lenses from prematurely becoming hairy due to "scars", the key is one sentence - "should be washed but not wiped".

Connoisseurs warn consumers that they should be careful not to allow the mirror to come into direct contact with hard objects on any occasion. Even if you use the softest wiping paper or flannel, even if you use "high-grade suede", fine dust particles, especially those that are difficult to detect with the naked eye, may scratch and tarnish the plastic lenses, even the most expensive plastic lenses cannot overcome this defect.

Correct cleaning method: It is best to wash with clean water (or add a small amount of dish soap) first, and then use a special cloth or high-quality cotton paper to blot the water droplets on the spectacle lenses (note: it is blotting, not wiping).

A better solution is to prepare a cylindrical plastic jar, the diameter and height of which can only fit a pair of glasses, or a glass; Then dilute it with dish soap and water and pour it into a jar (you can submerge the whole pair of glasses); Soak your glasses for at least 5 minutes before washing your face and brushing your teeth every day, rinse off the foam with tap water, and then dry the water droplets on the lenses. Insisting on doing so every once in a while is undoubtedly better than any "panacea" for the maintenance of plastic lenses.

Around 600, the thickness of a resin lens is usually determined by the material and refractive index of the lens. For lenses with the same refractive index, the glass material is thinner than the resin, and the high refractive index is thinner than the low refractive index. Resin aspheric lenses with a greater refractive index can be selected, which are thinner relative to the lens thickness.

Of course, the higher the refractive index, the more expensive the lens is. In addition, the chosen frame should not be too large, otherwise the edges of the lens will be thicker.

Whether the plastic lens is transparent or yellow, the two lenses need to be of the same color, and the second is that it is slightly pale yellow and transparent from the side.

1 The glass lens of sunglasses has better optical performance than that of lenses made of other materials. The surface of the glass lens has a very high hardness, the chance of scratching and wearing it is relatively small, and it is not easy to deform, and it has a very strong gloss and texture, which is visually superior to plastic lenses.

2. The plastic lens of sunglasses is the most used type of all lens materials at present, and it contains a chemical component of a plant. Plastic lenses are lightweight, and they are more impact-resistant, and they have a good UV protection from the sun, making them more comfortable and healthy to wear than glass lenses.

3 Sunglasses glass lenses: Sunglasses glass lenses have high hardness, and its heat resistance is also very good, it can be heated to more than 300 degrees, but sunglasses glass lenses are easy to break, and it is also relatively heavy.

Sunglasses resin lenses: The heat resistance of sunglasses resin lenses is not as good as glass lenses, it can only be heated to about 80 degrees, and it is not wear-resistant, and it is easy to be scratched by foreign objects. However, it has good drop resistance and its texture is lightweight, but it is easier to process than glass lenses.

Sunglasses glass lenses: The glass lenses of sunglasses do not have UV protection.

Sunglasses plastic lenses: The plastic lenses of sunglasses can block the sun's ultraviolet rays, which can prevent the eyes from being damaged by various harmful rays, and its light transmittance is stronger than that of glass lenses.

41.Improper wearing of sunglasses is easy to cause eye diseases, so it is best not to wear sunglasses in cloudy days, indoor and other dark conditions.

2.People with glaucoma should not wear sunglasses. After wearing sunglasses, the visible light entering the eyes is reduced, and the pupils will naturally open for a long time, which is easy to induce an acute attack of angle-closure glaucoma, with symptoms such as eye redness, eye pain, and sharp vision loss.

Children under the age of the age should not wear sunglasses for long periods of time. Because his visual function is not fully developed, wearing sunglasses for a long time may cause amblyopia.

The advantages of glass spectacle lenses are that they are wear-resistant, can be wiped with a cloth, and are easy to care for. The disadvantages are heavier, easy to break, and accidental eye injury.

There are many advantages of plastic lenses:

Lightweight: Plastic lenses weigh only half of glass lenses, reducing the heaviness of glasses;

Safety: Plastic lenses are not fragile and will not injure the wearer's eyes due to accidental lens breakage.

Clear: Plastic lenses have higher light transmittance than glass lenses, and vision is clearer. High-quality plastic lenses have less dispersion, can see more delicate and sharp, and correct vision better.

Health: Plastic lenses can be filmed to block up to 99% of the sun's ultraviolet rays and protect the eyes from ultraviolet rays. The disadvantage is that it is not wear-resistant, it is easy to scratch, and the lens care should be careful, and it is better to rinse with water rather than wipe with a cloth.

Based on these pros and cons comparison, I prefer resin sunglasses and sunglasses.

Yes, generally sunglasses are not resin, they are PC. Women rarely have glass, men's general glass is cheap, Lei Peng is good but very expensive to more than 1000. New, qualified lenses are not harmful to the eyes, you choose a thickened PC polarizer with a radian that is not too large (the arc may be dizzy), the polarizer is better than ordinary sunglasses, in addition to blocking sunlight, ultraviolet rays, but also filtering reflection, refracting sunlight.

It is especially suitable for outdoor sports such as fishing, driving, mountaineering, skiing, etc. There are more than 100 general brands and about 300 advertising brands. The lens of poor quality is about 50 thin.

Glass is better than plastic, and it is better to have branches, so as not to hurt the eyes.

Personally, I think it's better to choose plastic lenses, glass lenses are now slowly obsolete, let me tell you why1 is lightweight.

2.Less prone to breakage: If the lens is broken, it will not only have fewer fragments, but also be less sharp, which can minimize the occurrence of eye and face injuries, which is the main reason why the lens is advertised as a safety lens in the market.

3.Can be dyed: Plastic lenses are easy to dye, and can be moderately matched with clothing and fashion.

4.Can block ultraviolet rays: Almost completely blocks ultraviolet rays with a wavelength of less than 350mm, and the effect is far better than glass lenses.

5.Strong anti-fogging: Because the thermal conductivity of plastic lenses is lower than that of glass, it is not easy to be blurred due to steam and hot water, and even if blurring occurs, it will disappear quickly.

6.Anti-dent: Generally, high-heat and small-volume substances are easy to cause dents and spots on the glass sheet, but if it hits the plastic lens, it will automatically pop open and will not cause any marks on the surface of the lens.

7.The surface reflection of plastic lenses is lower than that of ordinary glass lenses, and they are less dazzling.

8.Plastic bifocal lenses do not have chromatic aberration, which is due to the fact that plastic bifocal lenses are constructed in one piece, so they are less *-shaped than fused glass bifocal lenses.

9.The light transmittance of plastic lenses is as high as 92%, which is more than 2% higher than that of ordinary glass lenses.

10.Plastic lenses are resistant to a wide range of chemicals and solvents, and almost all household solvents and chemicals will not affect or damage them.

It is recommended to use plastic lenses, because the frames of sunglasses are generally larger, and if they are equipped with glass lenses, they will be heavier than those of resin.

Resin will not break, once the glass has a heavy object hit the glasses, it is easy to cause the glass to break, and bad luck will hurt the eyeballs.

Glass is better than plastic, and it is better to have branches, so as not to hurt the eyes.

Clear: Plastic lenses have higher light transmittance than glass lenses, and vision is clearer.

I hope Nanfeng's answer can answer your questions, if you are satisfied with Nanfeng's service, I hope you can give Nanfeng an evaluation I wish you a happy life and good health Thank you!

For lenses for sunglasses, both nylon lenses and plastic lenses are common options. Nylon lenses have strong abrasion resistance, impact resistance and light weight, and are suitable for use in high-intensity activities such as sports and outdoors. Plastic lenses, on the other hand, are mainly thin and transparent, which is suitable for long-term wear due to their pros and cons.

Therefore, it doesn't matter which one is better, you need to choose which material to use for sunglasses lenses on a case-by-case basis.

If it is a high-intensity activity such as sports and outdoors, it is recommended to choose nylon lenses. Because it has good impact resistance and wear resistance, it can provide better protection against external forces such as sudden impact. In addition, the nylon material also has good flexibility, which is easy to process into different shapes of lenses and adapt to different frame designs.

If it is a casual wear in daily life, it is recommended to choose plastic lenses. Resin lenses are relatively thin and transparent, with good optical properties, as well as a certain degree of flexibility and abrasion resistance, so they are suitable for daily wear.

However, it is important to note that no matter what type of lens it is, it needs to have adequate quality assurance. If it is damaged during use or there is a quality problem with the lens, it will cause great damage to people's eyes. Therefore, when choosing sunglasses, you need to choose a brand with a good reputation, and choose a channel with a complete after-sales service system to buy.

Finally, for consumers who buy sunglasses for the first time, I hope to remind everyone that when choosing sunglasses, you should not only pay attention to the lens material, but also pay attention to the design, size, material quality and other dimensions of the frame. In this way, you can better choose sunglasses that suit you and provide better protection for your own eye health. The bridge <>
