Is fluorescent lamp harmful to eyes when it is used as a desk lamp?

Too much light is definitely harmful to the eyes.

In addition, fluorescent lamps are generally flashing frequently, so it is recommended to buy eye protection lamps. There are also two kinds of eye protection lamps. One is to change the low frequency flash to the high frequency flash, so that you can't detect it. The other is to change it to direct current, so there is no strobe at all, which is much less harmful to the eyes.

PS: Professionals will know that stroboscopic light in led is mostly serious, but you can't see it.
