What are prescription sunglasses? Any prescription sunglasses limitations?

[Rocklin]

My friend advise me to wear prescription sunglasses. I don't have a clear understanding of prescription sunglasses. Are they really quite helpful.

RX sunglasses means prescription sunglasses, that is to say your prescription can be added on the sunglasses lenses. When it comes to sunglasses and if you have a vision problem that requires corrective prescription eyewear, RX sunglasses can be one of your best choices. Prescription sunglasses are available for virtually any lens prescription, including bifocal and progressive lens options.
