FAQ
Can I become dizzy when wearing glasses?
That can only happen at first. Afterwards, the natural habituation to glasses ends this.
Can I use any type of contact lens?
No. Only rigid lenses are recommended. And usually the time of adaptation of the patient and his vision to these lenses is somewhat prolonged.
