Several times during a solar cycle, after intense solar eruptions, these lights are bright enough to be seen with the naked eye.
(Blue Aurorae in Mars’ Sky Visible to the Naked Eye, NASA)
Macroscopic inspection commonly used to describe physical objects that are measurable and observable by the naked eye.

While either the enzyme or the antibody is bound to an immunosorbent substrate, they both retain their biologic activity; the change in enzyme activity as a result of the enzyme-antibody-antigen reaction is proportional to the concentration of the antigen and can be measured spectrophotometrically or with the naked eye.

Though initially visible with the naked eye, it quickly faded and now requires powerful telescopes to see the remains of this merger, a dim central star surrounded by a halo of glowing material flowing away from it.

(Gross, NCI Thesaurus)

(Plaque Forming Unit, NCI Thesaurus)
A measure of viable infectious entities expressed in millions in the specimen or product defined as the smallest quantity that can produce a cytopathic effect in the host cell culture challenged with the defined inoculum, visible under the microscope or/and to the naked eye as a plaque.
(Million Plaque Forming Units, NCI Thesaurus)
A measure of viable infectious entities expressed in hundreds of millions in the specimen or product defined as the smallest quantity that can produce a cytopathic effect in the host cell culture challenged with the defined inoculum, visible under the microscope or/and to the naked eye as a plaque.
