Hello
What is lens in corel drawn what we can make in it
It is "special effects" on vector objects without changing the actual object. Look it up on youtube, lots of cool video tutorials there.
Lens is the name given to several transparent effects in CorelDRAW, if your working in CMYK make sure that you have soft proofing set up to your CMYK and activated while working of the effect does not display properly on screen.
"lens" is the generic name of several effects that could be applied to both vector and bitmap objects, such as the several modes of Transparency, fish eye, invert, etc. Some lens are aavilable on the transparency tool, others under the "lens" docker
