Computer vision syndrome ( CVS) is a condition resulting from focusing the eyes on a computer or other display device for protracted, uninterrupted periods of time and the eye's muscles being unable to recover from the constant tension required to maintain focus on a close object.
Cone cell. Cone cells or cones are photoreceptor cells in the retinas of vertebrates' eyes. They respond differently to light of different wavelengths, and the combination of their responses is responsible for color vision. Cones function best in relatively bright light, called the photopic region, as opposed to rod cells, which work better in ...
Minoxidil was the most effective of the three. So, if you’re looking for proven hair loss treatments, minoxidil (or finasteride, for that matter) is definitely a better bet than ketoconazole ...
