The choice between readers and bifocals depends on your specific vision needs:
Readers: Single-vision reading glasses are designed solely for close-up tasks like reading books, magazines, or using smartphones. If you only need help with near vision, readers are a simple and effective solution.
Bifocals: Bifocals have two distinct optical powers in one lens: one for distance and one for near vision. They are ideal if you need correction for both distance and reading.
