Qualis® silicone hydrogel contact lenses

Eye problems frequently caused by long wearing hours


Hydrogel contacts limit less oxygen to pass through the lens to the cornea, and will cause a number of problems such as red eyes.


A nonwetting lens lacks the normal lubrication provided by the tear film and can create mechanical irritation.


Eye fatigue is caused when we spend more time staring at digital screens with uncomfortable lens. The tired eye feeling may start to hurt or not seem as clear.

Does any of the above problem bother you?
Now, you have a new choice!


With Qualis ® HDK, contact lenses enter the new world of Linofilcon

Produced with new material and advanced technology, your eyes deserve the best


Soft silicone hydrogel lens material set new standards for comfort and fitting¹.


Qualis 38HDK enables the product to combine the moisturizing factor by itself. The moisture lens surface effectively avoid dry eyes².


Oxygen delivered to the eye is more than it can breathe and helps keep your eyes healthy³.

1 Flexible low modulus lens:0.45Mpa
2 With coating technology and edge design, it keeps tear movement and effectively prolongs the tear film break up time, the higher hydrophilicity of the surface leads to better wearing comfort. (Patent No. : US011194077B2)
3 The new generation of material – Linofilcon A contains high oxygen permeability (DK/t 125).

About us

Our value

“The eye is the lamp of the body. So, if your eye is healthy, your whole body will be full of light; but if your eye is unhealthy, your whole body will be full of darkness.”____Matthew 6:22-24

We care your vision, we care your eyes. We do our best to meet the patients’ needs and wellness. It’s the reason we provide the premium and affordable Qualis ® HDk. In latin, Qualis means “Quality”, and we urged ourselves to develop high quality silicone hydrogel contact lenses for everyone, everyday and everywhere.

Our technology

The new launched high oxygen permeability hydrogel contact lenses are produced by our advanced R&D team which has accumulated decades of development experience in the field of contact lenses.

We create a new generation of material – Linofilcon A. Combined with the surface modification technology of high-end medical materials, it breaks the product myth of “the higher the oxygen permeability, the harder the material”. With special polymer design, the product is no longer hard. The unique design of the formula enables the product to combine the moisturizing factor by itself. We also refresh the new manufacturing process to achieve excellent wettability.

All of the technologies aim to provide YOU the unforgettable and wonderful wearing experience!


What is the difference between the silicone hydrogel material and traditional hydrogel material?

The biggest difference between these two materials is the oxygen permeability (Dk/t), the oxygen permeability (Dk/t) of the water gel contact lenses is about 20~30 on average, however, the oxygen permeability of the new high oxygen permeability silicone hydrogel contact lenses (DK/t) is above 100(QualisR is 125). Its high oxygen permeability allows the eyes to maintain health under long-term wear.

Is there an adaptation period for silicone hydrogel products?

Silicone hydrogel contact lenses contain silicone, which has the characteristics of high oxygen permeability. Compared with traditional hydrogel materials, it is slightly harder. Very few people (about 1%) may experience some adaptation symptoms and need to adapt to the initial stage of wearing. It varies from person to person and the average adaptation takes about 1 to 3 days.

How are Qualis® contact lenses so comfortable?

Unlike ordinary silicone hydrogel contact lenses, Qualis® contact lenses are produced by advanced coating technology and edged design, the flexible low modulus leads to soft fitting and the excellent wettability allows long wearing hours. They are so easy to wear, you’ll love them.

Who are Qualis® contact lenses for?

Qualis® contact lenses are designed for people who want to experience healthy daily disposable contact lenses that feel like nothing. Try it now!
