I always wear makeup with contact lenses on. Most of the points are covered by Lavanya. I would like to add a couple of point;
1. I am not a fan of eye-pencil. I love gel-eyeliner, it stays well and does not smudge easily.
2. Do not line the inner waterline, just concentrate on the outer part of the waterline.
3. I always use an angled eye-liner brush for a better result.
Hope this helps.
