Preventing fogging of spectacles whilst wearing a
protective face-mask
M.J. REED
Department of Accident and Emergency, Royal Infirmary of
Edinburgh, Scotland, U.K.
Sir: The wearing of protective face-masks and visors in the operating theatre, and during the resuscitation of trauma victims is an established practice in modern day medicine. The problem of fogging of vision corrective spectacles when wearing a surgical face-mask or visor is well known to all those who are unfortunate enough to need to wear them.
The simple and effective method of fitting a face-mask described below eradicates the problem of fogging and requires no alterations to existing standard face-masks and visors.
The face-mask is donned in the usual way. However, care is taken to make sure that the upper part of the mask (with the contained metal strip) that is in contact with the nose and cheek, is well fitted. The upper lateral 3cm on both sides of the mask (at the outer edge of the cheeks) are then turned forwards to form a shallow curve (Figure 1).
The mask-ties are then secured in the usual way, taking care not to pull the lateral wings backwards when tying the upper tie.
