Night lenses

Wearing night lenses gives you sharp vision during the day without having to wear glasses or contact lenses. Night lenses are a great alternative if you don’t want to wear glasses or lenses during the day and don’t want to opt for radical laser treatment.

Information on the fitting

How night lenses work

The principle is simple: while you sleep, the lenses correct your eyes without you noticing. Their special shape ensures that the front of the cornea flattens slightly, which improves your vision. Depending on the stiffness of the cornea, this provides sharp vision for 1 to 2 days, while your eyes get complete rest during the daytime. Visser works with night lenses from the FreeView programme, which consists of expert advice and intensive guidance, including regular follow-up checks.

Children and contact lenses

We only measure night lenses for children in a strongly protocolled research setting, with the aim of collecting data on myopia control (reducing the deterioration of the eyes). The child’s eye is closely checked every three months and the lenses are replaced annually. Unless it concerns myopia control in a research setting, we do not measure night lenses for people under 18.


  • Good daytime vision without glasses or contact lenses
  • Optimal results after one week
  • No final surgery


  • When stopped, it takes time for the cornea to return to its normal shape
  • During that time, the strength of the eye varies considerably
  • This strength change must be absorbed by wearing daily contact lenses
  • Regular check-ups are necessary when stopping

Frequently asked questions

  • A new fitting of night lenses costs € 122,- and a readjustment costs € 82,-. After the adjustment process, a subscription can be taken out and from that moment on these costs are included in the subscription.

    Night lenses are offered as standard in a subscription form. You can wear night lenses in a subscription from €35,95 per month. If  you are under 22, you will receive a € 5,- discount on the monthly amount. The amount includes check-ups (every three months) and new lenses every year.

    For FreeView lenses there is a deposit of € 75,- per lens. You will get this deposit back after returning the lenses (in whatever condition), provided that they are returned within three months after you cancel the subscription.

  • Orthokeratology lenses exert corrective pressure during the night on (the epithelial cells of) the central cornea, which is thereby flattened (to the extent necessary). During the day, when the lenses aren’t worn, the cornea only retracts very slowly, allowing the wearer to see clearly without the use of aids.

  • Because orthokeratology lenses are worn during the night, less moisture reaches the eye. This can make the eye quite dry. In the past, it was thought that this would lead to more infections. However, studies have shown that ortho-k lenses do not lead to a significantly higher number of infections. Since the very start, Visser Contactlenzen has only prescribed night lenses under strict protocols. The fact remains that the risk of infection with night lenses is by definition higher than with soft myopia-inhibiting lenses. If your child’s myopia can be slowed down using soft myopia-inhibiting lenses, this option is always preferable to ortho-k lenses.
