But this light is reflected onto a wall, so it is not shining directly into the retina.
The back lighting is being disbursed onto the wall rather than directly into your eyes.
Are projector lights harmful?

Is the blue light from phones harmful?
The take-away from their research is clear: retinal produced by blue light is toxic to most types of cells. The shorter wavelength of blue light compared to other types of light, packs greater energy, generating retinal which is toxic to photoreceptor cells in the retina. “ Blue light appears to damage retinal cells .
Do projectors hurt your eyes?
A projector screen may have more viewing area, but they are thin and lightweight. That makes them easy to pull down and roll up after use. While a small screen does emit a lot of light, because it is small and your room is dark, your eyes remain dilated. This causes too much light to enter your eyes, causing eyestrain.
Do movie theater screens emit blue light?
Blue light is everywhere.
Most notably, the display screens of computers, electronic notebooks, smartphones and other digital devices emit significant amounts of blue light. The amount of HEV light these devices emit is only a fraction of that emitted by the sun.
Can I replace TV with projector?
Projector/screen combinations simply have to work harder to get anywhere near as bright as even a budget LED TV, and the trouble with projector bulbs is that they dim over time — ultimately burning out — and are costly to replace. There’s a reason movie theater screens are easy on the eyes.
Do projectors emit UV light?
DLP projectors use UHP lamps high intensity light that emit ultraviolet radiation (UV) and infrared radiation (IR) invisibke to the human eye. Most counterfeit lamps lack any of these features.
Can laser projectors damage your eyes?
