| Веки девочки были воспалены. | The girl's eyelids were inflamed. |
| Гримёр приклеил ресницы к её векам. | The make-up man glued lashes to her eyelids. |
NB When the word веко functions as a subject and does not have a descriptive modifier, the construction веко у + Genitive is often preferred to (a) and (b), above: | |
| Веки у девочки были воспалены. | The girl's eyelids were inflamed. |
| верхние/нижние веки | the upper/lower eyelids |
| Верхние веки у девочки были воспалены. | The girl's upper eyelids were inflamed. |
NB Note that, unlike many other body parts that come in pairs, веко cannot be modified by the adjectives левое and правое: | |
| веки левого глаза | the left eyelids (upper and lower) |
| веки на левом глазу | the (upper and lower) lids on the left eye |
| верхнее/нижнее веко на левом/ правом глазу | the upper/lower lid of the left/right eye |
