why can't you read in dim or bright lighting
Because in dim lights, there is hardly any lights to reflect, which makes it harder to see but on the other hand if it is a bright light there is plently of light to reflect s â¦ o that you can see it.he two ligh energy waves that you can't see are ultra-violet (UV), and infra-red (IR).  Ultra-violet light waves are measured at 380nm and below, infra-red light waves are â¦ 750nm and above.  Normal light that you can see resides between these two regions.
