Spherical Weekly Contact Lenses

Clinical Positioning and Performance

A seven day discard limits late cycle deposits and microbial load while keeping per day cost below single use wear. Weekly spherical lenses maintain stable end of day comfort and optics for routine myopia and hyperopia, and often rescue patients who dry out or build deposits on monthly schedules.

Ideal Candidates and Advantages

  • Predictable hygiene: Simple weekly discard discourages stretching
  • Lower deposit load: Short cycle curbs protein, lipid, and debris buildup
  • Broad power ranges: Common spheres covered without custom orders
  • Mild dryness or allergy: More frequent resets reduce irritation
  • Cost balance: Cheaper per day than dailies, cleaner than monthlies
