Left eye dominant

^^^^^^^^^^^^^^this^^^^^^^^^^^^^^^^^^^^^^^^^,,,,,,w hy is your left eye open

Because for many shooters it's uncomfortable, and strains the eyes.

As Robin said, if the vision in your right eye is good enough (corrected with glasses/ prescription lens if needed), shooting right handed will be easier, not requiring learning new muscle memory in your left hand. If buying kit, second hand right handed gear tends to come up more often than left handed.

The only point I'd add is that anecdotally a translucent blinder may not be effective. Although a dark blinder is not normally recommended as the imbalance of light strains the eyes, this is lesser evil if you can still see the sights through a translucent blinder.
