+25.00 D up to -25.00 D
6 months

Contact lenses perfectly matched to your eyes. Sharp image, even at higher strengths. The unique design of the BYO AB guarantees superb comfort and uniform movement. The front of the lens contains so-called aberration-free optics (AB technology), which gives you razor-sharp vision even at higher strengths whether you’re looking through the center or through the edge of your lenses.

Features of BYO AB:

  • Stable vision
  • Doesn’t take long to get used to
  • Customization

BYO AB contact lenses are for every lens wearer who has demanding requirements for sharp vision. This soft contact lens lasts as long as six months, even with longer wear times and when working in dry environments. The lenses are particularly suitable for people with higher strengths, as well as higher cylinder strengths.

BYO AB custom lenses last as long as six months. We recommend replacing the lenses after six months. 

Wearing contact lenses carries a potential risk of infection. Therefore, you should always follow the advice of the specialist and handle lenses correctly. For example, never clean lenses with water or put them in if your eyes are irritated. See the manual for all information on how to properly clean, store and use lenses. The manual can be obtained from your eye care specialist. The specialist works according to a protocol and makes sure you are properly informed and your eyes are checked regularly. To confirm that both parties will follow the safety instructions, the specialist will ask you to sign a lens agreement.

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

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.
