1. Blu-Cut Screen Shield

An integrated molecular filter that selectively blocks high-energy visible (HEV) blue light emitted by laptops, smartphones, LEDs, and monitors. Relaxes the ciliary eye muscles, relieves end-of-day migraines, and protects your natural sleep hormone (melatonin).

2. Photochromic (Sun-Adaptive)

Smart, light-responsive molecules embedded directly into the lens. They remain crystal clear indoors under artificial room lighting, then rapidly transition into rich, glare-cutting sunglass tints within seconds of stepping outdoors into UV sunlight.

3. Color Tint Studio

Permanent, optical-grade color infusion crafted with CR-39 resin and certified UV400 sun defense. Transform any optical prescription frame into iconic designer sunglasses with your choice of solid tones, gradients, or custom photo matching.

Step 03 in the Consultation Wizard • Lens Thickness

Select Thickness

The higher your prescription power, the thicker standard optical glass becomes. A higher refractive index bends incoming light more efficiently, requiring significantly less material to achieve the same visual clarity.

Thickness Level Refractive Index Recommended Power Range Profile Reduction
Normal 1.56 Index Up to ±3.00 Sph (Cyl up to -2.00) Baseline Standard
Thinner 1.67 High Index ±3.25 to ±7.00 Sph 35% Thinner & Lighter
Thinnest 1.74 Ultra-Thin ±7.25 and above 45% Thinner & Lighter
Step 03 in the Consultation Wizard • Performance Coatings

Select Coating

Every optical lens features an Anti-Reflective Coating (ARC) that controls reflections, durability, and visual clarity. The residual color you see is the functional wavelength being reflected away.

Green

The dependable everyday optical baseline. Provides essential digital blue light filtering and standard glare defense for regular daytime use.

Cannot find the exact hue you want? Our bespoke optical dye laboratory can recreate any shade using two seamless methods in the consultation wizard:

palette Method A: Digital Palette Builder

Build your own tint using our live interactive color controls:

  • Solid Tone: Pick any custom primary HEX color code.
  • Dual Gradient: Pick distinct Top and Bottom tones to design your own gradient fade.
  • Darkness Control: Calibrate your optical density from:
    • 25% (light indoor cosmetic tint) • 50% (medium tint) • 70% (classic sun) • 85% (heavy sun protection)

photo_camera Method B: Reference Photo Matching

Have an inspirational look from Pinterest, Instagram, or a celebrity sunglasses frame?

  • 1-Tap Upload: Attach an image or screenshot directly inside the consultation wizard.

Common Queries

Frequently Asked Questions

Clear, honest answers to help you navigate your lens selection with complete confidence.

help_outline What is Pupillary Distance (PD) and do I need to measure it? expand_more

PD is the horizontal distance in millimeters between the centers of your two pupils. It aligns the optical focal point directly in front of your eyes. For mild-to-moderate single vision prescriptions under ±3.00, industry standard averages (63 mm for men, 61 mm for women) deliver crisp vision without distortion.

help_outline What if I have high astigmatism or a high cylinder power? expand_more

Standard stock lenses support cylinders up to -2.00 or -4.00. For high cylinder powers or complex cross-compound prescriptions, custom surfaced grinding is required. In such cases, our optical team will personally contact you after checkout to ensure your lenses are crafted to medical-grade tolerances.

help_outline How does the Buy 1 Get 1 (B1G1) offer apply to lenses? expand_more

When you add two frames to your cart, the equal or lower-priced frame automatically becomes FREE. If you configure both pairs with standard Single Vision lenses and Green coating, the lenses are included at no extra cost.

help_outline Do Photochromic lenses darken while driving inside a car? expand_more

Standard photochromic molecules react to direct UV sunlight. Because modern automobile windshields filter out UV rays to protect the car interior, photochromic lenses will stay clear or tint only lightly while driving inside a car, but darken to full sunglasses outdoors in natural daylight.

help_outline Which lens index thickness should I choose for my prescription? expand_more

For mild powers up to ±3.00, our Normal 1.56 index is lightweight and dependable. For powers between ±3.25 and ±7.00, Thinner 1.67 index is 35% thinner to prevent side edge bulge. For strong powers ±7.25 and above, Thinnest 1.74 index is 45% thinner, eliminating heavy soda-bottle edges and eye distortion.

help_outline What is the difference between Green, Magenta, and Crystal Blue coatings? expand_more

Green is our standard everyday anti-reflective coating with digital blue light filtering. Magenta adds high-contrast night driving comfort against harsh LED headlights and enhanced scratch resistance. Crystal Blue is our flagship tier with ultra-low reflection for photos/calls, super-slick 1-swipe smudge clean, and ultimate scratch protection.
