Micas

[poli]

I have heard the term micas used at opticians. Does it refer to frames?
I this term strictly Mexican?

[Rusty]

armazones = frames

micas = lentes

I looked around a bit and saw that a handful of things can be called micas.
Basically, anything using a laminate or a protective cover match.
So, lenses can be called micas because they offer a protective cover and nowadays most are coated with a protective film.

Also called micas:
sheet protectors
laminated cards
tail lights
back lights
protective covers for iPhones

Thanks Rusty. I wasn't sure if the micas were frames because the tortoise shell appearance of mica or lens as you clarified for me. In the past I believe mica was used as a glass substitute.

Rusty is right, we use "mica" many transparent (mostly protective) plastics. In Mexico we don't use the term for car lights, but I guess it would be understood in context.

- Las micas de mis lentes oscuros tienen mi graduación.
My sunglasses have my prescription. (By the way, is "prescription" the right word for the many diopters my eyes need?)

- ¿Me puede enmicar esta credencial para que no se doble?
Can you laminate this card for me so it won't get folded?

- Puse los papeles en una mica para que no se ensucien.
I put the documents in a sleeve so they won't get dirty.

Angélica, prescription is the right word, but the way I would phrase your example in English is I have prescription sunglasses. (Actually I have photochromatic lenses, so I no longer need separate prescription sunglasses, but I used to have them so I'm familiar with the vocabulary).

I tried to make the sentence using "micas" as the subject, but it's true it doesn't sound very natural. Thank you!
(I do have separate lenses because I didn't like the shade the photochromatic ones were acquiring over time.)
