Answer:
Clara should use computer lenses and artifical tears.
The computer lenses help block blue light from entering your eyes which would help with the headaches and help you focus on something further away. The artificial tears help lubricate dry eyes which prevents or in Clara's case, reduces/relieves eye strain.
I would say that the best option would be a multimedia card.
It would depend on the movie and the theater policy.....
Hope this helps have a good day
