Better one eye than quite blind.

Having something limited is preferable to having nothing at all. The image of impaired sight stresses that an incomplete advantage can still preserve a valuable degree of ability, access, or hope.

The saying can counsel acceptance of a lesser option when full success is unavailable. It does not praise deficiency; it weighs an imperfect result against total loss. Because its bodily image may sound blunt, state the practical point directly in sensitive situations.

Use it when someone must choose between a partial benefit and none, such as retaining resources or opportunities after a setback. It suits practical advice about preserving what remains, but in sensitive situations it is better to express that point directly than invoke the image of disability.
