Does sleep help reduce strain?
Yes and no. If a person is under mental strain during the day, then this will carry over into sleep. Even during sleep, eyes can still be very active during a period know as REM, or Rapid Eye Movement, a phase of sleep during which dreaming takes place. Some people find their vision is best in the morning, certainly the result of sleep — while others find it markedly worse! The effect sleep has on your eyesight may be affected by the tension your eyes are under before you go to sleep, the amount of light in the room while you’re sleeping, what you ate before going to sleep, etc. In general, though, if you are able to achieve complete relaxation before you lie down, the effect on your eyes the next morning will be positive. Unconscious patterns of muscular tension are however generally not cured by sleep, nor are muscular weaknesses.
