Which LED light is best for eyes?
Soft white LED bulbs still give off a bright cast. Soft white is a better option because it isn’t as glaring, although there are warm hues, as well. Regardless of the shade, LED bulbs are among the safest lights for your eyes. They rank highest in energy efficiency, too.
Can bright lights permanently damage your eyes?
If the light is not quite so bright, chronic exposure over days to weeks can cause permanent damage. This is thought to be due to what is called photo-oxidative damage; the light reacts with the retina to produce molecules that are very reactive and cause damage to surrounding molecules.
Why do doctors flash a light in your eyes?

Can halogen lights damage your eyes?
The filament of incandescent lamp can reach thousands of degree Celcius and energy created by halogen bulbs is in the form of infrared radiation (heat). The infrared that cause cataracts has wavelength 1 500-800µm.As a result, the thermal effects cause lens protein denaturation and cataracts after long time.
Is white LED light bad for eyes?
Since LEDs are so bright, there are questions whether or not they can do damage to our eyes if used overtime. Don’t worry, though. The short answer to this is no, they won’t hurt your eyes.

However, if the eyes are exposed to a high enough level of light, such as a nuclear explosion, the blindness can become permanent. Flash blindness may also occur in everyday life.
How long does flash blindness last?
During daylight, flash blindness does not persist for > about 2 minutes, but is generally seconds. At night, when the pupil is dilated, flash blindness will last longer. Partial recovery may be expected within 3-10 minutes in daylight, longer at night.
