thats a totally subjective question. i'll try hard to answer it:
does tinting the glasses increase your ACUITY? meaning can you read smaller letters if the glasses are tinted? NO.
but a lot, and i mean a LOT of patients with all kinds of vision
disordersAdjustment disorder
Anorexia nervosa
Asperger syndrome
Autism
Autoimmune disorders
Bipolar disorder
Bipolar disorder
Bleeding disorders
Borderline personality disorder
Bulimia
Chronic motor tic disorder claim that they "feel more comfortable" or "have an easier time" when they wear tinted glasses. they do not have increased acuity, but they are less light sensitive and claim that they feel they have increased contrast in certain situations.
so the short answer is it depends on who you ask.
your next question will be what
colorColor blindness
Color blindness tests
Color vision test/type of tint is best for a keratocone, and i have no idea.
good luck.
