Complete set of transparent optical lenses — 11 pairs (22 pcs) with the following ADD (near‑addition) powers: ADD 1.00, 1.25, 1.50, 1.75, 2.00, 2.25, 2.50, 2.75, 3.00, 3.25, 3.50 Key benefits Full range of ADD powers: Provides small incremental steps from +1.00 to +3.50 so you can match the exact near‑vision correction needed. Practical quantity: 11 pairs (22 pcs) give multiple spares or allow different strengths for different tasks, reducing the need for frequent replacements. Clear, neutral vision: Transparent color preserves true color perception and contrast for close work. Optical lens structure: Designed for dependable refractive performance appropriate for near‑vision addition requirements. Why this solves common problems Avoids guesswork: The stepped ADD range helps you identify the precise near‑addition that improves comfort and reduces eye strain during close tasks. Cost‑effective backup: Multiple pairs let you keep lenses in different locations (home, office, workshop) or swap strengths as your needs change. Consistent performance: Optical lens construction provides predictable correction without introducing tint or false color. Important attributes Function: Optical lenses for near‑addition (ADD) correction. Power options: Exact ADD values listed above for accurate selection. Quantity: 11 pairs (22 pcs) included. Color: Transparent for natural color transmission. Performance: Engineered as optical lenses to provide consistent near‑vision addition. Compatibility notes (practical guidance) Intended for use wherever transparent optical ADD lenses are required — for example as replacement or supplemental lenses in systems or frames that accept add‑on optical lenses. Because these are specified by ADD power and are transparent optical lenses, verify physical fit and mounting method before installation if you plan to use them with a particular frame or optical assembly. Typical use scenarios Reading and close work: Use the appropriate ADD power for reading books, newspapers, or labels to reduce eye strain and improve comfort. Detailed tasks and hobbies: Select the strength that gives the clearest near focus for sewing, model building, electronics , or crafting. Screen and device use: Choose the ADD value that provides comfortable close viewing for smartphones, tablets, and portable devices during extended use. What to check before use Confirm that the optical lens format and size are compatible with your frame, holder, or device. Select the ADD power that matches your current near‑vision requirement or consult an eye care professional for precise fitting.
