Gravitational lensing due to earth

It is known that light from stars bend near surface of sun due to its mass. Similarly light will bend near earth's surface (may be insignificant due to less mass). My question is that sunlight that strikes earth's surface travels a straight path from sun or a curves near earth's surface ?

 It depends on the trajectory of the light. If it is traveling perpendicular to the Earth's surface, the light will only be slightly blue-shifted. Otherwise, it will be slightly bent by the Earth's surface. Basically. All light will tend toward the center of mass of the Earth. You are correct though, the amount of curvature or blue-shifting is pretty insignificant.

I am new to general relativity.

1)Can we mathematically calculate the amount of curvature or deviation ?
2) Can we calculate the angle at which sun light strikes the surface of earth (at a particular place) considering this bending (even if its is small)
3) Are you really sure, light tends towards center of mass ?
