Seconds big eyes mixed girl! About the pure dry goods tutorial

At present, there are too many rumors about the beauty, what is the black workshop recycling and reselling, what is the eye that will grow parasites, will accidentally move to the back of the eye to make the eyes inflamed, and the beautiful baby will want to become bigger eyes. Also afraid of hurting the window of the soul, they all expressed the need for someone to come to the name of the United States~

What is beauty?

Beauty, that is, colored contact lenses, contact lenses, also known as contact lenses, are soft glasses that are worn on the cornea of ​​the eye to correct vision. Beauty lenses are contact lenses that can change the color of the pupil.

Everyone should know that the cornea is awkward? It is very very important for people. Many eye diseases are caused by corneal lesions, so Teacher Bu reminds everyone that you must protect it.

Therefore, the choice of the United States is the need to do a good job, here are a few parameters to buy when you must look carefully! They are water content, diameter, base curve, and type.

PS: I suddenly gave you some basic knowledge about the beauty before I thought about it. It may take a long time. We don’t remember it. Now, there are some incomplete reviews. Let’s review + add focus today~

degree

It is the degree of myopia in the eye. My sister's paper knows how much myopia is.

The general beauty can not correct astigmatism, wearing a clear view, but there will be divergent aperture around the object, the lens that wants to correct the astigmatism needs to be customized, the price will definitely be paralyzed.

The choice of the degree of beauty is different from ordinary glasses. The degree below 400 degrees can be consistent with the degree of glasses. 400 degrees - 500 degrees minus 25 degrees, that is to say, if the public is about 425 degrees of myopia, it is necessary to choose 400 degrees. And so on, 500 degrees - 700 degrees minus 50 degrees, 700 degrees - 1000 degrees minus 75 degrees.

If you don't have the degree you need, you can choose a bit lower than the degree of myopia. Attach the glasses degree and the invisible eye degree conversion table:

Water content

The water content will affect the softness and hardness of the lens. The lens with high water content is soft and comfortable to wear in the eyes, but it is also easy to deform and break, and the lens is easy to lose moisture.

Lenses with low water content have higher hardness and are less prone to deformation. Relatively speaking, it is not easy to dehydrate, but the wearing feeling may be more comfortable without the lens with high water content.

The water content is generally divided as follows:

Less than 38% is called a low water lens, 42% - 60% is a medium water content lens, and more than 60% is called a high water lens.

However, the higher the water content, the better. The high water content lens will continuously absorb the moisture in the eyes, causing the eyes to dry up, and the lenses are easily broken. Therefore, the baby who is easy to dry eyes suggests choosing a low water-containing lens~

diameter

The diameter is also the diameter of the lens, which determines the effect of the beauty in the eyes.

The diameter of the enamel is generally calculated according to the diameter of the tiling, that is, the enamel is flattened by measuring the diameter of the color portion of the belt. The average diameter of the cornea of ​​the Chinese is about 11.5-12mm, so the choice of lenses is preferably around 14mm.

The diameter is not the bigger, the better, especially the eye itself is not a very big sister paper. If you choose a large diameter beauty, it will look too big and super black, very terrible... The brain fills the horror film. The female ghost of the black eye, you will know ~

Base arc

Isn't the beauty bowled? The base arc refers to the curvature of the curved part of the bowl. The arc is always known.

It is best to go to the hospital to measure it. It is not suitable for the beauty of the eye base. It will feel very uncomfortable to wear, have a foreign body sensation, or it will slide (that is, it does not fit the eyeball and slides to the white part of the eye). Generally, the base arc is 8.4-8.6mm.

Discard type

In general, it is recommended that you choose the daily throw or the annual throwing beauty, the daily throwing is convenient, the annual cost-effective, perfect to meet the demand.

Daily throw

Advantages: it is easy to wear when worn out, comfortable to wear, no need for care products, easy to use;

Disadvantages: The price is not beautiful, when you use it, you will lose a little pain...

This public move generally chooses the daily throw type, because I need to face the computer for a long time, the beauty is only worn when the makeup is worn, the cost of the daily throw is more suitable for me~

Annual throw

Advantages: good formability and low price;

Disadvantages: Wearing too long, easy to breed bacteria.

Before I knew about the beauty, I always chose to throw it. After that, I found that I can only wear it for a half year at most, and I don’t remember cleaning when I don’t wear it. As a result, many of them are thrown away without the shelf life. It feels too uneconomical~

Two-week throw (half-month throw)

Advantages: moderate length of use, comfortable wearing and cost-effective;

Disadvantages: It is easy to forget to wear time, sometimes it is not timely.

I have bought a half-month-old beauty, she said that it is also very easy to use, I feel that the daily throw is too expensive, the sisters who can not be hygienic in the year can choose this ~~
