I feel it is better for my eyes in all environments than bright mode. I am very nearsighted. But, both modes hurt your eyes as long as you have to read on screen or even on paper. My aunt used to be pretty nearsighted as a student (-6.00 on both eyes), after she graduated and started a job that only required a little reading, her vision improved dramatically to better than -1.50 within a year. A few years later she completely got rid of eye glasses.
