Bifocals & Trifocals
For generations, bifocals and trifocals have helped people see clearly at multiple distances. At Simply Eyes Hawaii, we still fit these traditional lens options for patients who prefer them. While most patients now choose progressive lenses for their seamless look, bifocals and trifocals remain a practical choice for certain vision needs.
What Are Bifocals and Trifocals?
- Bifocals: These lenses have two distinct zones—one for distance and one for near vision. A visible line separates the two.
- Trifocals: These lenses add a third section for intermediate vision (like computer work), creating three zones in one lens.
Both designs correct presbyopia, the age-related condition that makes reading up close more difficult.
Benefits of Bifocals and Trifocals
- Clear vision at multiple distances
- Affordable and widely available
- Easy to adapt to for those who’ve worn them before
- Durable options for everyday use
Available Materials for Bifocals & Trifocals
Bifocals and trifocals can be made in a variety of lens materials, so you get the right balance of clarity, comfort, and durability:
- CR-39 (plastic): Affordable, lightweight, and good optical quality
- Polycarbonate: Impact-resistant and safe for kids or active wear, with built-in UV protection
- Trivex: Lightweight, durable, and sharper optics than polycarbonate
- High-Index Plastics: Thinner, lighter lenses for stronger prescriptions
| Lens Type | Vision Zones | Appearance | Pros | Cons |
|---|---|---|---|---|
| Bifocals | Distance + Near | Visible line (2 zones) | Affordable, simple, easy to adapt to | No intermediate vision, “image jump” effect |
| Trifocals | Distance + Intermediate + Near | Visible lines (3 zones) | Adds computer/intermediate correction | Lines more noticeable, image jumps |
| Progressives | Distance + Intermediate + Near | Seamless, no lines | Natural transitions, modern look, one pair for all | Slight learning curve, higher cost |
