    UV is actually what we often call ultraviolet rays. Have you found that sunglasses are marked with such words as UV400 and UV300? This is because this pair of sunglasses can prevent wavelengths below 400nm or 300nm from being filtered out. Generally, good sunglasses lenses will add anti-UV particles to further absorb ultraviolet rays, to prevent ultraviolet rays from entering the pupil, ultraviolet rays are the external factors leading to cataract.


    With the progress of technology, contact lenses have also increased the technology of anti-UV, so wearing contact lenses can also be anti-UV. So how about UV resistance of contact lenses?

    We recommend pharnorcia silicone hydrogel contact lenses, a contact lens that can resist UV. Our lenses are made of new silicone hydrogel developed by pharnorcia scientists for several years, and are processed by the advanced CNC lathe through the molding method, which increases the oxygen permeability and comfort of the lenses. Moreover, the lens is added with anti-UV ingredients developed by pharnorcia, which can block ultraviolet rays to a certain extent, reduce the damage to the eyes caused by the accumulation of ultraviolet rays, and improve the wearing comfort.

   The pharnorcia soft hydrophilic contact lens is made of the third generation hydrophilic silicone hydrogel polymer composite material with independent intellectual property rights. The third generation material has a strong ability to resist dirt and protein precipitation, and does not require the surface treatment technology of the first generation. It also has excellent moisture retention, and does not require the addition of moisturizing factors in the material like the second generation. The material has high oxygen permeability, excellent surface wettability, excellent water content, high softness of the lens, lightness and insensitivity, and is suitable for wearers with different corneal base arcs.

    New silicone hydrogel contact lenses with high oxygen permeability and excellent water content are introduced by pharnorcia. Breathing pharnorcia soft hydrophilic silicone hydrogel contact lenses refuse to be bound by plastic, allowing the eyes to breathe freely, so that the lenses float above the eyes like "clouds". The unique high ratio of oxygen permeability and water content can maintain the stability of tears and the continuous circulation of oxygen, so that the lens is suspended above the cornea.
