You've said this nonsense before. Front light on eink is no difference, as indeed is any light of the same brightness with no front light on.

No, see a different consultant, because that doesn't cause conjunctivitis. It's simply a lie that a screen at normal brightness causes any health issue.
You can get headaches from using a screen to read if either you need glasses,
or there are reflections from objects a metre away or more. Medical facts, not opinions. A sheet of polished glass in front of a paper book in a brightly lit area with people moving around will give a headache.

Conjunctivitis (red or pink eye) is an eye condition caused by infection or allergies.
You usually do not need treatment if you're an adult. But your child might need to see a GP or have urgent treatment. If your baby is less than 4 weeks old, contact your GP.
Some sexually transmitted infections (STIs) can cause conjunctivitis. This type takes longer to clear up.

Pink eye is most often caused by a viral infection. It also can be caused by a bacterial infection, an allergic reaction or — in babies — an incompletely opened tear duct.
Though pink eye can be irritating, it rarely affects your vision. Treatments can help ease the discomfort of pink eye. Because pink eye can be contagious, getting an early diagnosis and taking certain precautions can help limit its spread.

There is also no medical difference between using a projector and a same size TV screen at the same brightness, arranged that there are no reflections off the screen.
Scaremongering with no scientific basis is not friendly.
