The eye is such an adaptable organ that it enables us to see in illumination that is close to darkness as well as bright daylight. Bright moonlight is measured as 0.1 lux and bright sunshine is measured as 100,000 lux.

To avoid eyestrain, it is recommended that illumination should 30 times as much as is required to just manage to do a particular job.
