 Composition:

1. **Lens Material:**

• **Plastic (CR-39):** Lightweight and offers good optical clarity.
• **Polycarbonate:** Impact-resistant and thinner than standard plastic.
• **High-Index Plastic:** Thinner and lighter, suitable for stronger prescriptions.

2. **Lens Design:**

• **Bifocal Segment:** The lower part of the lens is designed for near vision, typically with a +1.5 diopter addition.
• **Distance Vision Segment:** The upper part of the lens is for distance vision, which may have a different prescription or be plano (no correction).

3. **Coatings:**

• **Anti-Reflective Coating:** Reduces glare and improves visual clarity.

2. **Visual Acuity Needs:**

• Suitable for those who require correction for both distance and near vision, allowing for seamless transition between different focal lengths.

3. **Occupational Use:**

• Beneficial for individuals who engage in activities that require both near and distance vision, such as reading, computer work, and driving.

4. **Convenience:**

• Ideal for patients who prefer not to switch between multiple pairs of glasses for different tasks.

### Conclusion:

Bifocal glasses with a +1.5 diopter strength are an effective solution for individuals experiencing presbyopia, providing clear vision for both near and far distances. It is essential for users to have a comprehensive eye examination to determine the appropriate prescription and lens design tailored to their specific visual needs.
