Regarding strain in the eyes

Q: There is a strain in my eyes. Reading has become difficult. What to do?

For the eyes you can try boric acid lotion; it should at least take away the pain.

You will have to be careful about your eyes. Reading by night (too much) is unadvisable. There are two suggestions of the Sun-treatment man which I have found to be not without foundation. First, one should blink freely in looking at things or reading and not fix the eyes or stare. Second, palming gives a very useful rest — palming means keeping the hands crossed over the closed eyes (without pressing on the eyes) so as to shut out all light.
