Sync lenses are a type of spectacle lens designed to reduce eye strain, particularly during prolonged close-up work or screen time. They combine a standard distance correction with a special 'boost zone' at the bottom of the lens.
Understanding Sync Lenses
Based on the provided information, SYNC lenses are characterized by two key features:
- Distance Power for Everyday Use: The main portion of the lens provides the necessary correction for seeing objects at a distance, suitable for general daily activities like driving, walking, or watching TV.
- Boost Zone: Located at the bottom of the lens, this specific area incorporates an increased amount of relaxing power.
The Purpose of the Boost Zone
The primary function of the boost zone is to reduce eye strain that occurs during prolonged activities requiring intense focus on near objects. These activities often include:
- Looking at digital screens (computers, tablets, smartphones).
- Reading books or documents.
- Any other 'near task' activities where your eyes are focused up close for extended periods.
By providing this additional relaxing power in the near vision area, the boost zone helps alleviate the extra effort your eye muscles need to exert when focusing up close, thereby minimizing symptoms of eye strain.
In essence, Sync lenses offer a convenient solution for individuals who spend significant time on near tasks, providing comfortable vision for both distance and close-up work within a single lens.
