“Safe Eyes” is an excellent program that relieves eyestrain symptoms usually caused by computer monitors. Besides full therapeutic eye training, “Safe Eyes” separately offers frequency, contrast, and pattern exercises; it also includes a special contrast sensitivity test.
I would like to mention that “Safe Eyes” was created for the DOS environment, and (unlike modern Windows PE files) its translation was a byte-for-byte manual language substitution that in itself was a delightful challenge for me.
If your contemporary operating system cannot run DOS programs, you can launch “Safe Eyes” using a free DOSBox emulator (from dosbox.com) by typing in and executing these commands one after another:
1) MOUNT C [DRIVE LETTER]:\[“SAFE EYES” DIRECTORY NAME] (for example, MOUNT C C:\SE ).
2) [DRIVE LETTER]:\[“SAFE EYES” EXECUTABLE] (for example, C:\SEEN.EXE ).
