Choosing the right eyeglass frame material is key to comfort, durability and style. If you’re unsure which of the four top materials—Acetate, TR-90, Stainless Steel or Titanium—fits you best (lighter? hypoallergenic? sport-friendly? budget-friendly?), we’ve got you covered.

Frame material directly impacts comfort and how well glasses fit your lifestyle. With years in the eyewear industry, Dollger focuses on high-quality materials to craft frames for all needs. Below, we break down these four materials by features, pros/cons and ideal users—plus how Dollger uses them to blend comfort and style.

1. Acetate – Synonym for Fashion & Texture

Material Analysis: Acetate is an eco-friendly plant-based material, top choice for high-end, stylish frames (cat-eye, thick square styles). Premium Acetate—often imported from Italy—outperforms regular plastic frames in texture.

Pros:

• High-end texture: Dense (1.2g/cm³) with a substantial feel; available in high-gloss, matte, gradient or tortoiseshell finishes, balancing appearance and quality.

• Rich colors: Thousands of shades (including tortoiseshell, amber) to match work, casual or vintage looks.

• Hypoallergenic & safe: No odor/irritation—80% less likely to cause allergies than cheap plastic frames, friendly to sensitive skin.

• Strong stability: Resists temperature/humidity changes; no deformation, good light-shielding to reduce lens glare.

Cons:

• Relatively heavy: Thick frames (over 20g) may press on the nose/ears, especially for high-myopia users with thick lenses.

• Insufficient toughness: Prone to breaking on impact (dropping, collision); hard to repair once broken.

• Wide price range: Budget propionate fiber options cost little, but premium Italian Acetate is pricier than TR-90.

Ideal For: Style-focused users who love vintage looks; low-prescription wearers; professionals (needing to show capable temperament); sensitive skin users with sufficient budget.

For style and texture lovers, Dollger uses premium Italian Acetate to blend vintage charm with modern design. Our tortoiseshell square and amber cat-eye frames keep the material’s quality while staying comfortable for commutes or dates.

2. TR-90 – Ultra-Light & Flexible "All-Rounder"

Material Analysis: TR-90 (Grilamid TR90) is a clear nylon from Switzerland’s EMS. Ultra-light and tough, it’s perfect for sports and daily wear.

Pros:

• Ultra-lightweight: Density 0.83-1.15g/cm³ (half the weight of traditional plates, 85% of nylon); 8-10g total, no nose pressure even after 8+ hours, balancing lens weight for high-myopia users.

• Super toughness: Memory polymer material, bends 180° without breaking; resists squeezing (bag pressure) and minor impacts—twice as impact-resistant as nylon.

• Skin-friendly & hypoallergenic: Food-grade (EU standard), no chemical residues, safe for sensitive skin.

• High cost-effectiveness: Mature production, affordable for students/commuters (daily or backup pairs).

• Heat-resistant: Withstands 350℃ briefly, not easy to melt/burn; no deformation in daily sun (avoid summer car exposure).

Cons:

• Limited styling: Soft material—hard to make complex carvings/edges; mostly simple rounded frames (casual, less delicate).

• Weak scratch resistance: Low surface hardness, easily scratched by keys/phones, affecting appearance.

• Heat-sensitive: Softens/deforms above 60℃ (summer cars), avoid long-term high-temperature exposure.

Ideal For: Students, budget-limited users; high-prescription wearers (reducing nose burden); athletes/active users; sensitive skin users; those needing backup glasses.

For lightweight, durable and affordable options, Dollger’s TR-90 line fits sports, school and commutes. Upgraded scratch-resistant coating adds durability—get a daily pair for under $50.

3. Stainless Steel – Durable "Cost-Effective Choice"

Material Analysis: Stainless steel is a common, strong, corrosion-resistant and affordable metal for slim, sleek frames—popular with men (business/casual styles).

Pros:

• Durable: High strength/hardness, no deformation/damage; lasts 4-6 years, resists daily impacts/wear.

• Strong corrosion resistance: Withstands sweat (salt/oil), no rust/discoloration, easy daily maintenance.

• High cost-effectiveness: Moderate price, cheaper than titanium/premium Acetate—great for budget-limited users pursuing durability.

• Sleek styles: Slim temples, semi-rimless/rimless designs; metallic shine, looking capable and high-end.

Cons:

• Relatively heavy: 18-20g—heavier than TR-90/titanium; may cause sore ears after long wear.

• Allergy risk: Nickel in some variants—about 30% of sensitive skin users may get red/itchy ears.

• Less stylish: Few colors, traditional metal look—less versatile than Acetate.

Ideal For: Budget-limited users, durability seekers; male wearers; outdoor workers (wear-resistant, corrosion-resistant); simple metal style lovers; non-sensitive skin users.

For men wanting durability and minimalism, Dollger’s stainless steel frames add nickel-free, hypoallergenic coating. Semi-rimless business and rimless lightweight styles keep the metal’s sturdiness—great for outdoor work or commutes.

4. Titanium – High-End & Comfortable "Gold Standard Material"

Material Analysis: Titanium (pure or β-titanium, an upgrade) is a high-end frame material—ultra-light, hypoallergenic, corrosion-resistant and strong, ideal for premium business frames.

Pros:

• Ultra-light & comfortable: Density 4.5g/cm³ (30% lighter than stainless steel); 9-12g total, almost no pressure for long wear—great for sensitive/high nose bridges.

• 100% hypoallergenic: Nickel-free, ISO 10993 certified—safe for sensitive/metal-allergic skin.

• Extremely durable: Corrosion/oxidation-resistant (no rust from sweat); twice as hard as alloy—lasts 10+ years, no temple deformation.

• Premium texture: Matte metallic finish—no chipping/oxidation, understated luxury for business scenarios.

• β-titanium advantage: Upgrade of pure titanium, blending pure titanium’s lightness with TR-90’s toughness; flexible for complex curved shapes, fitting facial contours better.

Cons:

• Expensive: Pure titanium frames over $300, β-titanium up to $500—for users with sufficient budget.

• Hard to repair: Complex welding process—needs professional tools/tech, higher repair cost than other materials.

• Limited styles: Mostly business/minimalist—fewer colors than Acetate.

Ideal For: Premium users with sufficient budget; professionals; sensitive/metal-allergic skin users; long-term wearers (8+ hours); comfort-focused users.

For those pursuing high-end comfort, Dollger’s titanium line uses pure/β-titanium with ergonomic design. Matte business and lightweight β-titanium sports frames maximize the material’s ultra-light, hypoallergenic advantages—pressure-free for all-day wear, perfectly suitable for business office and long-term wearing needs.
