Geometricaly.

Is it convex or concave?

You will find the derivation in http://scienceworld.wolfram.com/physics/ThickLensFormula.html

Look at Gullstrand's Equation http://hyperphysics.phy-astr.gsu.edu/Hbase/geoopt/gullstrand.html#c1
for example http://cref.if.ufrgs.br/hiperfisica/hbase/geoopt/priplan.html
I hope that helps
