Well after a little research..here are shades and sunglasses perfect for round faces.But before that a lil info:
Frames should make the face appear longer and thinner. In general, look for frames equal to or slightly wider than the broadest part of the face. Minimize the curves and add definition with soft, angular, rectangular styles or double brow styles. Higher temples will create a longer profile. Sunglasses with brow bars also pull the eye upward, making the face appear longer.
Frame suggestions : Wider frames with angular / rectangular styles
SKIN
Pale complexions
Try lightweight frames or those with a touch of colour such as rose or amber. Tortoiseshell frames suit fair complexions (avoid darker versions) but clear, blue or green tinged frames tend to drain colour from cheeks.
**
Dark complexions**
Olive, Mediterranean, Golden or Asian skin and dark hair can look stunning in silver, gold or clear frames – but avoid black which can be too heavy. **
Dark/Black complexions**
All metallic frames suit black skins and amber often works well – be very careful with black frames, which can look spectacular or awful!
**
HAIR**
Soft & curly
Enhanced by delicate shapes, rimless frames and translucent colours
Very curly
Choose a frame that follows your hairline. Classic small frames are advisable
Short
Geometric frames, or rounder frames look best
Very short
Bold colours and designs, as well as decorative styles
Long hair
Try the frames with both your hair up and down, as the change in style may alter the look of the frames
