How lighting needs to change your eyes?

Select light bulbs with a high colour rendering index(CRI) 

CRI indicates how accurately a light bulb renders or displays colours to the human eye. It is rated on a scale from zero to one hundred, with one hundred being the best possible rating. 

Since aging eyes yellow, they have a harder time distinguishing between blues, purples, and greens ,which can decrease contrast in text and images and make it harder to read.As a result, providing the most accurate colour rendering indoors in areas where it matters. Such as desks, reading chairs ,office spaces, and hobby or craft tables will make it easier for older members fo your houshold to distinguish between different hues. Select a light bulb with a CRI of at least 80 such as these LED light bulbs.
