Am I really more likely to get cataracts if I don’t wear sunglasses?

It depends. There are many things that have been linked to increase cataracts aging, diabetes, certain medications, smoking, trauma, and uv light exposure. Increase uv light has been showing to increase cataract formation. A more important reason to wear sunglasses is to prevent damage to the retina which captures the light we see. Cataracts can be removes, but retinas ca not be repaired once damaged.
Likely yes; depends. Cataracts (white lens change): most often due to or made worse by (most common first): aging, genetics predisposition, excessive sun exposure, smoking, diabetes, steroids, previous trauma, inflammation, infection in the eye causing inflammation; previous intraocular eye surgery; other genetic issues; can be congenital.
