Fogging Gas Permeables

I tried wearing gas lenses ten years ago, but after wearing them for only ten minutes, they fogged up. I tried different cleaning solutions, but nothing helped. What would be the reason for this?

Fogging is normally caused when your tears cannot form a stable film over the lens.

The tear film breaks up rapidly and causes a fogging effect.

The causes can be varied. It could be as simple as the lens not being cleaned well prior to insertion, grease can easily cause the tear film to break up, as can protein on the lens. Alternatively, it could be that your tears are of a poor consistency and so do not wet the lens well.

Gas Permeable Materials have also advanced tremendously over the last 10 years, so that patients that once could not be fitted with lenses very often can be fitted with the new generation materials.

It would be worth trying again with your practitioner
