It seems everyone has a different "route" psychologically to reach a state of meditation. I've found more often than not I can achieve this with my eyes open, through what would loosely be defined as "empty stare". You're starring, but not focusing, or particularly looking at anything. This has a few positives and can enhance a variety of activities. Often used by martial artists, when trying to detect movement from opponents. You're not starring at any particular part of their body, or eyes/face, your eyes are just open and docile and reacting purely on instinct and movement. Over focusing leads to delayed and flawed reactions.
As for pure meditation, I've found the method of focusing on breath, a gentle breeze, or a particular posture can help bring me into a state of meditation more quickly and effortlessly. But again, everyone has their own methods and approaches.
