Light travels at a constant velocity in a straight line through space. Gravitational lensing is an artifact of the kinks in spacetime created by massive objects; those kinks change what a "straight line" is for the light passing through that area of spacetime.

Time isn't affected by gravitational lensing per se. Gravity warps spacetime, and light is distorted (lensed) by the warped spacetime.

I was thinking it’s been bent so much it added 3 light years which sounds like a lot till you take into account that’s over a 3.2 billion light year trip.
