Is it possible to buy glasses for daltonic people?!
Question: Not to give completely normal colour vision.
There are techniques (e.g. x-chrom contact lens), and one or two types of specially tinted glasses that can increase discrimination of some colours
For example the the US "Colormax" of which the FDA said:
"...The lenses do not help wearers perceive or appreciate colors as people with normal color vision do, but merely add brightness/darkness differences to colors that are otherwise difficult or impossible to distinguish.
ColorMax lenses are designed to improve discrimination of specific colors that look the same to people with red/green color deficiencies. However, discrimination of at least some other colors is actually impaired."
