After finally surviving the high temperature of the autumn tiger, ushered in the days of cool autumn wind. When we step out of the room one after another, come to nature to breathe fresh air, and feel the "freshness of autumn", don't forget to bring a new refreshing experience to your eyes.

Pharnorcia silicone hydrogel contact lens is a contact lens product carefully developed by Pharnorcia's top expert team from Beijing Normal University, Peking University, Zhejiang University, and American Ivy League schools for several years. It can provide long-term wear for users who need to wear it for a long time. Moisturizing and excellent visual experience. The new third-generation silicon hydrogel material used in the product enables it to achieve high oxygen permeability, meet the oxygen demand of the cornea, and care for eye health.

Silicone hydrogel, as an organic polymer material, can be used to make contact lenses. It is currently recognized as a contact lens material with high oxygen permeability. Silicone hydrogel can combine the hydrophilicity and softness of traditional hydrogel materials, and at the same time fill in the lack of oxygen permeability, which can provide better protection for eye health.

Since the development of contact lenses, silicone hydrogel can be regarded as a huge breakthrough in material technology. In the past, hydrogel contact lenses have always occupied the mainstream of the market. The lenses are very hydrophilic and comfortable to wear in the eyes, but the disadvantages are also prominent. The oxygen required for corneal respiration is only transmitted by water, so the water content needs to be kept at a relatively low level. Higher levels, which means water evaporates faster and eyes can feel dry sooner. Silicone hydrogel combines silicon components on the basis of traditional hydrogels. Because the solubility of oxygen in silicon is very high, the oxygen permeability no longer depends solely on water content, which solves the problem of lens moisture evaporation. problem.

Pharnorcia silicone hydrogel contact lenses use a new type of hydrophilic silicone hydrogel polymer composite material with independent intellectual property rights. The material has a strong ability to resist dirt and protein precipitation, and does not require surface treatment technology like the first generation; and has very good Humidity, no need to add moisturizing factor to the material like the second generation. The lenses are highly soft, light and feel-free, and are more suitable for sensitive eyes.

Put on pharnorcia silicone hydrogel contact lenses to make your eyes feel "refreshing in autumn".
