It's forcing your pupils to constrict. Decreasing the aperture size on a lens increases the field of view. So, while your eye might not be able to accommodate at the correct distance given the current convergence point, there is more room for error. It's a fairly common method in photography, in cases where one might have difficulty getting a correct focus on a subject. It's not a "fix", but a compensation.
