Special Spectacle frames are made to fit Divator, Spiromatic and Sari masks; thus catering to a wide spectrum of mask users in applications as diverse as paint spraying to diving.
The frames have shortened temple arms, designed to fit in the mask by means of clips, attached to the lugs, moulded to the inside mask surface.
This means that the mask seal is not broached, whilst; when used; the spectacles stay in place, in the correct position for parallax free vision.
For those who regularly need to use a face-mask, this system is a boon - maintaining good 'face-fit', best safety and clear vision.
We provide the service for your glasses. All we need is a copy of your current prescription, provided by your optician. You will be contacted if your prescription falls outside the usual range of scripts provided in our standard pricing, or if your script is not available in Polycarbonate, if that is the lens material you chose.
We will post your spectacles to you about ten days after confirming the details with you. There is no need for the frames to be fitted by a dispensing optician.
