Clear lens caps

[Vintage_Photographer]

Having read up about the benefits of exposing lenses to light to prevent fungus it occured to me that translucent lens caps might be useful?

Any thoughts?

I have 3D printer so might have a go at knocking sone up.

I think lens caps used to be black to prevent film exposure when shutters were this and that. Digital times I can not see a reason why not transparent?

I can see a reason for lens caps on lenses attached to cameras to be black - sunlight through the lens focused on a shutter or sensor could damage them through heat but lenses stored off camera... I can imagine transparent lens caps would help keep fungus at bay.

There are a lot of misconceptions about lens fungus out there . The most pervasive is that fungus "jumps" from lens to lens . If you expose a lens to conditions in which fungus will grow, fungus will grow. The spores are everywhere.

That said, fungus does indeed grow better in dark settings, but it -can- grow in the presence of light if other conditions are ideal, i.e., ones that are warm and damp.

So clear caps might help a little? But probably not nearly as much as a humidifier/air conditioning where they are stored will.
