3D Effect

[Acurado]

I have been noticing this effect since last week , never noticed this before with older glasses
I think my glasses are making text appear weird on screen, as if it had depth.
On white background the black text looks layered  , text looks convex "bulging" ,  i have an impression that even with my naked eye im seeing this effect, but very subtle.
I have been wearing these glasses for two years, I am mildly myopic. I have been searching for this subject, but all I get on search engine is about "new glasses, need to get using to"  but tthese glasses i have been got used for years,  whats is this? My prescription changed?  
Even with pictures this happens
If I go to youtube right now, the sidebar video pictures looks like it has depth

Whats is this? My prescription changed? Astigmatism changed?
Does eyeglasses refraction gets bad after years?
Or is it my brain?  I'm just waiting for a new appointment and new glasses, but I want these questions answered

2 year old glasses are not 'new'.   The most common thing that would cause this especially young healthy person is axis or amount of astigmatism.  Yes you do need to make an appointment, ideally with an Eye MD ophthalmologist, for a complete medical eye exam, refraction with dilation of the pupils.
