If you are a first-time wearer or have sensitive eyes, and only intend to wear them for short-term social occasions, we highly recommend choosing colored contact made of HEMA NVP composite hydrogel material, which offer higher wearing comfort and better adaptability.
F1：What materials are used for colored contact lenses?
F2：What is the difference between them?Which one should I choose?
Silicone hydrogel is currently the contact lens material with the best oxygen permeability,Its oxygen transmission mechanism involves introducing “silicone” as independent oxygen channel, enabling dual-channel oxygen transmission and no longer relying entirely on water. Its oxygen permeability is generally above 100, far exceeding that of hydrogel. it does not depend on water for oxygen transmission, its water content is very low (around 38% to 45%),Due to its low water content, the lenses not absorb moisture from the eyes, making them highly suitable for people with dry eye syndrome or those who wear lenses for long periods (over 8 hours).However, because it contains, the lens material is relatively harder, and people with sensitive eyes may feel a slightly stronger foreign body sensation.
In contrast, hydrogel is the material used for all contact lenses and lenses. Its oxygen transmission mechanism relies on water to transport oxygen, so its oxygen permeability is relatively low (usually between 20 and 30). However, its water content ranges from 55% to 69%. Although its oxygen permeability is limited and its water content is high, the lenses will absorb moisture from the eyes during wear, which easily lead to dry eyes when worn for long periods (over 4-6 hours). Nevertheless, its lenses are very soft, easy to adapt to for first-time wearers and cause almost no foreign body sensation. Furthermore, silicone hydrogel material is not easy to print with complex and exquisite patterns, which is why most colored lenses on the market are made hydrogel material.
Therefore, if you are a first-time wearer or have highly sensitive eyes, and primarily wear them for short-term social occasions, it is strongly recommended that choose hydrogel colored contact lenses.
F3：Are there any recommended products? What are its advantages?
Of course, Yilala is a good choice. It uses HEMA NVP composite material, which is also a type of hydrogel. H materials are more prone to adsorbing impurities, but after copolymerizing with NVP, the wearing experience is significantly improved. This is because NVP neutralizes the slight negative surface of HEMA lenses, thereby effectively resisting the deposition of proteins and lipids. For colored contact lenses, this ensures that the complex colored patterns remain clear and sharp throughout the day, prevents lenses from becoming blurry and yellowed, and significantly reduces the risk of eye infections or allergic reactions (such as giant papillary conjunctivitis). However, its structure is relatively soft and easily or damaged, especially for monthly and yearly lenses. But there is no need to worry too much, as Yilala can be purchased for only RM9.90, making more cost-effective in the market.
