Precisely understood customer needs and context enable crafting differentiated sunglass designs tailored for your objectives.
Chapter 3 – Exploring Frame Shape and Style Options
The frame shape dramatically impacts aesthetics and fit. Considerations include:
- Classic styles like aviators, wayfarers, rounds, ovals, cat eyes
- Mixing retro, modern or futuristic styling cues
- Masculine vs feminine shapes and sizing
- Integrating geometric or ornamental patterns
- Front view proportions and side profile contours
- Accenting design focal points like the brow line or temples
- Creating consistently styled families or collections
- Trending shapes identified in market research
- Limiting overly aggressive or impractical styling
Balance aesthetics with wearability constraints to craft attractive comfortable frames.
Chapter 4 – Selecting Frame Materials and Color Palettes
Materials influence the look, feel and price point:
- Metals like titanium, aluminum, stainless steel, monel
- Plastics such as acetate, propionate, polycarbonate
- Natural materials like wood, leather, bone
- Combinations like wood temples on acetate fronts
- Matte, glossy, or metallic finishes
- Transparency for clear or translucent frames
- Density and thickness factors impacting weight
- Flexibility and durability considerations
- Color palettes including classic neutrals (black/brown), bright accents, gradients
Consider the sensory impression you want the frames to impart when selecting materials.
Chapter 5 – Exploring Lens Options and Treatments
Lens choices optimize visual acuity and protection:
- Clear or tinted lenses to control light levels
- Polarized lenses to cut reflected glare
- Mirror coatings for enhanced aesthetics
- Photochromic lenses that adaptively darken
- Blue-light filtering lenses to protect eyes from screens
- Oleophobic anti-smudge and hydrophobic water resistant coatings
- UVA/UVB protection against the sun’s rays
- Base lens material options like polycarbonate for impact resistance
- Lens thickness profiles and optical qualities
- Prescription compatibility if desired
Combine features balancing visual performance, optical clarity and style.
Chapter 6 – Developing Custom Embellishments
Optional decorative touches provide further distinction:
- Color gradients or patterns like woodgrain
- Metal plating or foil accents
- Laser etching or engraving logos and textures
- Inlaying semi-precious stones or crystals
- Signature shaping like notched temples
- Integrating hinge adornments and medallions
- Hand painting or airbrushing motifs and designs
- Decorative rivets, cutouts, or piercings
- Vintage-style fabric temple tips
- Creative packaging like hard cases or pouches
Subtle embellishments complement frames without overpowering aesthetics.
Chapter 7 – Sketching Initial Concepts and Technical Drawings
Bringing ideas to life on paper is crucial:
- Sketch styling options balancing aesthetics and function
- Highlight or render focal design elements
- Capture views from multiple angles like profiles and top down
- Ensure consistent styling language across frame fronts and temples
- Maintain realistic proportions that suit human anatomy
- Use digital tools to experiment with colors and materials
- Develop technical drawings with dimensions, views, materials, etc.
- Outline visual brand language and styling cues
- Create digital 3D models to preview physical appearance
Iteratively refine sketches, renderings and technical drawings to clearly convey the designs.
Chapter 8 – Evaluating Fit, Proportions and Sizing
Consider ergonomic factors for comfort:
- Target fit demographics like men, women, teens, youth
- Recommend measuring key dimensions like head circumference
- Accommodate variance in nose bridge width and ear position
- Allow adequate length for different face shapes and sizes
- Specify grip shapes and lengths for stable temple holding
- Ensure frames don’t pinch nostrils or bump cheeks
- Test sizing on diverse user groups through prototyping
- Design adjustable components like rubber nose pads
- Specify weight limits to prevent excessive pressure
Thoughtful sizing and proportions maximize wearability.
Chapter 9 – Prototyping Design Iterations
Physical prototyping validates concepts:
- Engineer CAD models for 3D printing eyewear or CNC milling
- Review accuracy of shape, dimensions and part fit
- Assess weight, balance and perceived quality
- Make fit adjustments and tweak curvatures
- Evaluate decoration techniques like surface textures
- Perfect technical aspects like hinge friction and flex
- Refine details with each version to finalize design
- Produce molds or tooling once perfected
- Share samples with focus groups for feedback
Repeated small-batch prototyping reduces errors and improves outcomes.
Chapter 10 – Testing and User Research
Trying concepts directly on users is invaluable:
- Recruit diverse survey participants representing target demographics
- Have user groups actually test wearing the prototypes
- Solicit feedback on style, fit, comfort, functionality
- Identify any pressing points, grip slippage, visual obstacles
- Assess fatigue wearing frames for extended intervals
- Evaluate stowing convenience like pocketing arms
- Make fit notes like temple length for different head sizes
- Observe usage behaviors like arm folding frequency
