Can You Guys Help Me?

Guys I Need Your Help. I'm Trying To Make An Eyes Blink Script That Works ONLY When A Player Become A Morph. I Don't want The Script To Work While There Is No Player In The Morph That Is In Work space And That Would Cause Lag. I'm Trying To Make The Script Works Only When A Player Become A Morph.

while wait() do 
    local script = Parent 
    local eye1 = player.eye1 
    local eye2 = player.eye2 
    eye1.Transparency = 0
    eye2.Transparency = 0
    wait(10)
    eye1.Transparency = 1
    eye2.Transparency = 1
    wait(1.5)
end
