Step 11 With the Ellipse tool (U) add a white ellipse. Go to Layer > Layer Styles > Blending Options. Change the Fill Opacity to 0, then select Inner Shadow. Use Pink for the colour and Linear Dodge for the blending mode. Set the Angle to 90º, the Distance to 0, the Choke to 14% and the Size to 250 pixels.

Step 12 Group this layer into another folder and make it invisible (Layer > Layer Mask > Hide All). Select the Brush tool (B) and with a medium-sized rounded brush, paint with white over the layer mask just so a little bit of the left and right areas of the ellipse are visible. Repeat the same technique to create another lens reflection, but this time smaller.
