What is the visual acuity of the construction worker with plaster in his eye?

In the case of the construction worker who has plaster in his eye, the visual acuity is likely to be significantly affected due to the foreign body presence. The presence of a foreign object can cause a range of issues including irritation, abrasion, and inflammation, all of which can lead to reduced visual clarity. The value of 20/50 suggests that the worker can see at 20 feet what a person with normal vision can see at 50 feet. This level of visual acuity indicates a moderate impairment, which is consistent with the ocular trauma and the presence of a foreign body such as plaster in the eye.

In situations like these, visual acuity may not be perfect and can vary based on the extent of damage or the immediate effects of the foreign object. Therefore, 20/50 is an appropriate representation of the likely visual capacity for a person suffering from such a condition, as it shows that while they can still see, their vision is significantly compromised.
