Discover the Precision7 for Astigmatism weekly lens: hydration, UV/blue light protection, and a 27-pack value. Learn if it fits your astigmatism needs.
Quick answer
The Precision7 for Astigmatism weekly lenses offer a balance of hydration, UV/blue light protection, and a generous 27-pack per box, making them a solid choice for astigmatism correction with weekly replacement.
Why consider Precision7 for Astigmatism?
Alcon's Precision7 for Astigmatism lenses are designed for those who need toric correction for astigmatism but prefer the convenience of weekly disposables. They provide consistent vision stability and are engineered to resist dehydration, which is a common issue with toric lenses.
The 27-pack per box is a standout feature: it reduces the frequency of reordering compared to standard 6- or 12-packs, making it a practical choice for consistent wearers.
Key considerations for astigmatism lenses
Toric lenses for astigmatism require precise alignment to maintain clear vision. The Precision7 uses a prism ballast design to keep the lens oriented correctly on the eye. This design is effective for most astigmatism prescriptions, but individual fit can vary.
Weekly replacement means you change lenses every 7 days. This schedule is ideal for those who want the hygiene of frequent replacement without the daily hassle, but it requires a consistent routine to avoid overwear.
Decision rules for choosing Precision7 for Astigmatism
- Replacement schedule fit: If you prefer to change lenses weekly (not daily or monthly), this 7-day schedule aligns with your routine. The 27-pack provides a 27-day supply per box, which simplifies ordering. Check your prescription: weekly lenses require consistent disposal after 7 days to maintain eye health.
- Hydration and comfort priority: The serafilcon A material and phosphate buffered saline solution are designed to resist dehydration. If dry eyes are a concern, this lens may offer better comfort than some other toric options.
- UV and blue light protection: Precision7 lenses include UV and blue light protection, which can reduce eye strain from screens and outdoor exposure. This is a bonus if you spend long hours in front of digital devices. UV protection is not a substitute for sunglasses; use both for full coverage.
