1. Different advantages
The advantage of hydrogel is that the lens is soft, elastic and very moist. It is very comfortable as soon as you put it on, as if nothing had happened. . The advantages of silicone hydrogel are good oxygen permeability, relatively low protein deposition, the lens is not subject to water deficiency and the more you wear it, the more comfortable it becomes.
2. Different disadvantages
The disadvantage of hydrogel is that the oxygen permeability of contact lenses made of this type of material is relatively low and the eyes tend to feel dry and short of breath. The disadvantage of silicone hydrogel is that due to the silicon component added to the lens, the lens will be relatively hard and may feel like a foreign body when worn.
3. Different oxygen permeabilities
Silicone hydrogel contact lenses generally have oxygen permeabilityxygen 5 times higher than hydrogel contact lenses. Because the oxygen permeability of hydrogel contact lenses is closely related to their water content. Generally speaking, hydrogel products with high water content will have higher oxygen permeability and higher corneal metabolism permeability.

Advantages of silicone hydrogel
Advantage 1: ultra-high oxygen permeability
The new contact lenses use hydrogel silicone gel material with high oxygen permeability. The unique structure of silicone hydrogel contact lenses greatly increases oxygen permeability, allowing the cornea to breathe oxygen freely, fundamentally avoiding redness, swelling, inflammation and other problems caused by contact lenses. corneal hypoxiaand effectively improving corneal health.
Benefit 2: Excellent comfort
After wearing regular contact lenses for a whole day, the eyes often feel dry, but after wearing silicone hydrogel lenses, it does not There is no much lower discomfort. The unique dual-channel technology of silicone hydrogel lenses gives them a dual-channel structure of water ions and oxygen ions, which can effectively alleviate air dryness and hypoxia.
Traditional lenses rely on water to conduct oxygen. Therefore, after the water in the lens evaporates, oxygen cannot penetrate the cornea well, which will lead to permanent damage to the cornea in the long term. Even if the new silicone hydrogel lenses are worn for a long time, the eyes will remain white and clear, without redness or corneal damage. May there be no more constraints on watchfulnessr late and working overtime.
Benefit Three: Reduce Natural Precipitates
Protein deposits are a common problem with contact lenses, and research has proven that silicone hydrogel contact lenses can reduce these deposits. The unique innovative surface treatment technology of silicone hydrogel forms a protective film on the contact lens surface that is only one hundred thousandth the thickness of a human hair.
Because they are filled with charged ions and electrons, under the action of biological principles, the deposited proteins will undergo ionization and decomposition, thereby reducing protein precipitation. The lenses will stay clean and extremely durable for a long time. .Better comfort.
What knowledge do you need to know to use anti-fever patches?
The scorching heat of summer makes people more and more inseparableair conditioners. Even though air conditioning allows us to lower the ambient temperature, it pollutes the indoor air and increases the outdoor temperature. Air conditioning is therefore a new technology which is not environmentally friendly. To this end, scientists have invented new environmentally friendly cooling materials.
A number of Japanese companies are developing a new building material that can reduce the temperature of residential and office buildings. They will establish a joint venture to achieve mass production of new materials within three years. This new material contains a photocatalyst made of materials such as titanium oxide, which has the property of absorbing large amounts of water when exposed to sunlight. If you paint a material mixed with a photocatalyst on the exterior walls and roof of a building and then pour water on it, the eau will spread finely and evenly, just as the building is sprayed with water. As water evaporates, it removes heat, significantly reducing the surface temperature of the building. According to experiments carried out last summer by the University of Tokyo in schools and hospitals, the use of photocatalytic materials on roofs would reduce the temperature of building surfaces by around 9 degrees Celsius. The same results were obtained after using photocatalytic materials on the blinds.
Foreign researchers have also developed an environmentally friendly cooling coating in recent years. This coating is applied to the roof if the outside temperature reaches 36 degrees Celsius, the inside temperature can be reduced. at 28 degrees Celsius, saving 40% more air conditioning energy. It is reported that this environmentally friendly and energy-saving coatinguses nanotechnology to transform a variety of inorganic raw materials into dense glass bubble-shaped particles. The infrared reflectivity of this full hollow insulating layer reaches 80%, and the ultraviolet reflectivity reaches more than 90%. , thereby reducing the thermal energy of solar radiation. However, general coatings currently on the market can only reflect 10-30% of infrared and ultraviolet rays.
It's very hot when you're outside in the summer. It would be much more comfortable to put on a cooling vest. The cooling vest developed by Chinese researchers is made of a fabric with a cooling function and a thermal insulation gel. Put it in the refrigerator or in ice water for a while before using to keep it cold. You will feel fresh after wearing it and have a refreshing effect. This vest is non-toxic, breathablet, lightweight, easy to clean and also offers UV protection. The hottest thing in summer is the mind, which makes people dizzy and unable to work or study. That's why someone developed a cool ice cap specifically designed to "calm" the mind. It is understood that experts also invented the cooling ice cap, which uses the principle of water evaporation to absorb heat and cool down. It not only can provide sun protection, skin care and eye protection, but also has good cooling and relieving effects. Clean the brain and refresh the mind, and has the function of protecting against ultraviolet rays. Summer brings a cold feeling to people, and it can be called a "small portable air conditioner". The hydrogel in the ice sheet has a certain cold storage effect, so the effect will be more significant if the ice sheet is placea in the refrigerator freezer for a while before use.
Some children's ice caps sold in pharmacies are now available. The heat patch has become a physical cooling item that many mothers prepare for feverish babies. Although this type of antipyretic patch is convenient, it is also intended for external use. It is specially designed to reduce fever in children and is patented by Sinopharm. It is conceivable that the effect on the baby will not be very significant. But some moms use these pediatric recuperatorsThere are still questions about thermal patches, so let's learn common sense about antipyretic patches for children.
Can adults use antipyretic patches?
Yes.
Although various brands of antipyretic patches are primarily aimed at reducing fever in infants and young children,antipyretic patches are physical cooling and are external products. They are equivalent to an ice pack and can maintain a cooling effect for 6 hours. It can also be used by adults without any side effects.
Is the antipyretic patch effective for adults?
The effect is not very good.
The principle of the antipyretic patch is very simple, it uses physical heat dissipation to achieve a cooling effect. Theoretically, any antipyretic patch that can be used by infants and young children can also be used by adults. However, due to the small size of infants and young children, the antipyretic patch contains fewer active substances, so its effect may not be obvious. when placed on adults.
How to use the antipyretic patch for adults
Adults can apply the antipyretic patchretic on their forehead, neck, temples or other areas requiring cooling or a cold compress in which they can be cut; corresponding sizes according to your needs. ; If you want to speed up the cooling, you can add multiple patches and place them simultaneously on large blood vessels such as the left and right axillary arteries and the left and right femoral arteries, which will help. reduce fever.
Can young children use adult antipyretic patches?
No.
Adult-specific antipyretic patches cannot be used on infants and young children. Since antipyretic patches for adults may contain many chemicals or allergens (such as alcohol, hydroxybenzoic acid), children are more likely to develop allergies when they are applied. Therefore, it is not recommendedto use adult antipyretic patches on infants and young children.
Notes:
Fever patches are sold for children, but many products are suitable for both children and adults. In addition, because children's skin is delicate, thin and rich in blood vessels, when they face fever, the effect of antipyretic patches is better than that of adults.
The antipyretic patch does not contain any other chemical agents and is based on the physical principle of water vaporization and heat absorption for cooling. Therefore, while using the antipyretic patch, you can also take other antipyretic medications, and they will not react with each other. Let's look at this in detail!
Can antipyretic patches and antipyretics be used together?
Yes.
The antipyretic patch does not contain any other chemical agents and is basedon the physical principle of water vaporization and heat absorption for cooling. Therefore, while using the antipyretic patch, you can also take other antipyretic medications, and they will not react with each other. If the child's body temperature still does not drop after using the antipyretic patch, parents should take the child to the hospital for treatment in time.
Can antipyretic patches and antipyretic suppositories be used at the same time
Yes.
The antipyretic patch is equivalent only to physical cooling and has an effect similar to applying a damp towel to the forehead. Antipyretic suppositories are antipyretic medications whose main ingredient is acetaminophen. They are administered rectally. There is no conflict between the two, so they can be used at the same time. However, the supAntipyretic medications have strong medicinal effects and are usually only used when the baby has a high fever and the body temperature exceeds 39 degrees. And it should be used under the guidance of a doctor.
Reduce feverIs it good to use the patch with antipyretics?
The antipyretic patch is equivalent to physical cooling, which is only partial cooling. It can be used as long as the body temperature rises. The antipyretic medicine is a pharmaceutical coolant and is generally used when the fever exceeds. 38.5 degrees. It is also used in conjunction with physical cooling to achieve better effect. Therefore, antipyretic patch and antipyretic medicine are used together to reduce fever from the inside out and act faster.
Under what circumstances can antipyretic patches be used simultaneouslyticks and antipyretics?
When the body temperature exceeds 38.5°C.
Generally speaking, antipyretics are necessary when the body temperature exceeds 38.5°C to avoid convulsions caused by too high a temperature. At present, the simultaneous use of the antipyretic patch can lower the local body temperature and relieve headache, dizziness and other discomfort caused by high fever. Using the two together can accelerate the drop in body temperature and promote recovery.
Can antipyretic patches and antipyretic medications be used continuously?
Antipyretic patches can be used, but antipyretic medications should not be used continuously.
The cooling of the antipyretic patch is based on the physical principle of water vaporization and heat absorption. It can be used in continu, and there is no need to pause for a while when the two coins are exchanged. .
Compared to antipyretics, since internal medicines contain certain chemicals, their continued use is harmful to the body, so you need to wait 6-8 hours between taking them.
I think the knowledge about antipyretic patches presented above can be a reference for everyone. Although antipyretic patches can be helpful when babies have a fever, people still make mistakes using them. However, if the antipyretic patch is used incorrectly and differently, it will worsen the baby's fever symptoms. Therefore, you should always follow the instructions when using the antipyretic patch for children.
