When RGP lenses for medical use do not offer the right solution, the BYO Premium KC lens is an excellent alternative. The soft silicone hydrogel material guarantees optimal oxygen permeability. This makes the lens particularly suitable for medical use.

You’ll love these features of BYO Premium KC:

  • Stable vision
  • Easy fit thanks to Flex Zones
  • Optimal thickness distribution

The BYO Premium KC soft custom lens is designed for people with irregular corneas. When the cornea is deformed or damaged, traditional contact lenses and eyeglasses are often unable to improve visual acuity. BYO Premium KC has so-called Flex Zones in the periphery that make the lens easy to adjust on the irregular cornea.

BYO Premium KC can be worn daily for a period of three months. We recommend replacing the lens every three months.

Before using your soft lenses, always read the package insert that is provided by your contact lens specialist.

Unica Sensitive or Ever Clean Plus are a good choice for intensive cleaning, disinfection, storage, rinsing and insertion of your BYO Premium KC lenses.

Unica Sensitive is an all-in-one liquid ideally suited to sensitive eyes due to the addition of hyaluronic acid, a substance that occurs naturally in the body. The lens fluid has a minimal concentration of preservatives and acts as a lubricant between the contact lens, cornea and eyelid.

The Ever Clean system is suitable for all lens types and is free of preservatives. It consists of a disinfectant based on 3% hydrogen peroxide combined with an innovative dual-focus effervescent tablet that provides thorough lens cleaning, disinfection, neutralization and moistening in just 2 hours. Unlike the standard Ever Clean liquid, povidone and lipase have been added to Ever Clean Plus. Povidone is an effective and long-acting humectant that contributes to the stability of the tear film. The enzyme lipase is effective against lipids that adhere both centrally and at the edges of the lens surface, contributing to thorough lipid cleaning.

Frequently Asked Questions

  • Which contact lens is best for my eyes?

    It depends entirely on you and your eyes. During an eye exam an eye care specialist assesses your eyes and looks at the strength and shape of your eye, among other things. You personal situation is also evaluated: When do you want to use them? How often? In what work environment? Based on all the measurements, you can choose the best lenses together with the specialist. Visit your nearest optician for an eye exam or consultation.
  • How do I clean my lenses?

    It is important to clean your contact lenses daily. The moment you remove your lenses, it is important to clean, rinse and disinfect them with the recommended lens solution as prescribed or advised by your contact lens specialist. Contact lens cases should also be emptied, cleaned and rinsed daily, as they can be a source of bacterial growth. Importantly, lenses, lens cases and other lens-related products should not come into contact with (tap) water because of the increased risk of microbial keratitis.
  • What should I look for in lenses for my child?

    Children can wear lenses as young as 8 years old on average. (1) Before a child can start wearing lenses, the eye care specialist explains what it means to wear the lenses and the responsibilities involved for the child, such as in the area of hygiene.
