Reflection to sunglasses PhotoShop for iPad.

[Cocogalesa]

Can anybody help please? I have PhotoShop installed on my iPad, but cannot see a tutorial to insert a reflection on sunglasses, specifically while using the iPad version. 
I see many tutorials for this on the PC version of PS, but cannot even find the Create Clipping Mask option.
