See an eye MD ophthalmologist for a complete medical eye exam. Ask that a macular OCT and Amsler grid test be done. If normal, monitor for changes. Many people report things like this. As discussed many times it is usually entopic phenomena related to the retina/macula shifting from dark adaptation (scotopic) to light adaptation (photopic) and the differences in rates of the macula and peripheral retina in making these changes. Living in a simulation, too much late night sci-fi.
