Deaf and Hard of Hearing Awareness:
Saw this via Google search...
Over time, I learned to take breaks. 10am, lunch time and 3pm. Just a 15 minute cat nap (set the phone clock alarm) At lunch time, i just stare off into the void to rest my eyes. If I don't take time to rest, I'm non functionable by 8pm.
It's not an old age thing, it's a hearing loss issue. Any degree of hearing loss, mild, moderate or profound.
One other tip; teach those that care, how to use the "talk to text" via your phone, or use email or use pen and paper, or a dry erase whiteboard. These methods can help reduce lip reading stress and some eyestrain.
