The mandatory use of face masks in indoor public spaces has created an added difficulty for those who are deaf or hard of hearing.

The masks cover the face making speech muffled, and obscuring the mouth, on which those who read lips rely.

That’s what’s led to the development of a clear plastic window in face masks that provide a view of the mouth.

Renee Phair Healey is a registered psychologist and director of the wellness program at the NL Association for the Deaf.

She says improving people’s ability to understand and communicate helps to ease anxiety, particularly when she thinks about deaf community members with complex health care needs and who require medical appointments.
