Yes if you are a vampire

Yes if you are a vampire

1. Vampires do not exist
2. Even if they did, if they can be seen in visual light there is no reason they would not be visible in a mirror. A mirror reflects all visible might by using a highly polished metal (usually aluminum but silver also works).

A surface will look shiny if imperfections or holes are less than 1/8 the wavelength of the photon being reflected. The grid in your microwave can be seen through in visible light but it reflects microwaves. Some of the old large satellite dishes used a wire mesh to save both weight and cost. The holes made no difference at all in the performance of the dish as the holes in the mesh perfectly reflected the radio beams.

Some evidence exposure to mirror images can modify the brain ...

"What do ya mean, 'its a mirror'?"

Why do you ask?

You're far more of a medical doctor than I am. I'd guess that seeing and learning about reflections is all part of the normal training of the human visual system.

<hums>There once was an ugly duckling, it's feathers all shabby and brown...
..."have a look in the lake and you'll see". And he looked, and he saw, and he said "I am a swan  - wheeee".   </hums>   :-)

Vertical mirrors aren't "normal": they don't occur in nature.

Some animals apparently think their reflection is another creature ...

Anyway aren't newborns extremely shortsighted ? ...

Newborns are short-sighted and can see only about eight to 15 inches (20 to 37.5 centimeters) away.

Once an infant discovers the concept of self...

Then a mirror might aid with proprioception.

I can't imagine any major problems form such exposure.

Here is a short article named "Why Babies Love Mirrors"...  and discusses adding them to a baby's playtime.
