Dispensing Optics Quiz

Dispensing Optics

Definition

Dispensing optics refers to the process of selecting and combining lenses, prisms, and other optical components to correct vision problems.

Types of Dispensing Optics

• Single Vision: Corrects nearsightedness or farsightedness in one direction (near or far)
• Bifocal: Combines two lenses for near and far vision in one frame
• Progressive: Gradually increases power for near, intermediate, and far vision
• Multifocal: Corrects multiple vision problems with separate lenses for each task

Dispensing Optics Steps

1. Measurement: Measure patient's pupillary distance (PD) and vertex distance (VD)
2. Lens Selection: Choose lenses based on patient's prescription, lifestyle, and frame style
3. Lens Combination: Combine lenses to achieve desired correction
4. Verification: Check lenses for accuracy and quality
5. Final Assembly: Assemble lenses into frames and adjust for proper fit

Key Considerations

• Lens Material: Choose from glass, plastic, polycarbonate, or high-index materials
• Coatings: Apply anti-reflective, scratch-resistant, or UV-protective coatings
• Tints: Add color or tint to lenses for cosmetic or functional purposes
• Prism: Add prismatic power to correct eye alignment or movement issues

Technology and Tools

• Lensometers: Measure lens power and axis
• Automated Edgers: Cut and shape lenses with precision
• Lens design software: Assist in designing and verifying complex lens combinations
