These are specialized prescription lenses primarily designed to correct a single field of vision (such as nearsightedness or farsightedness), just like traditional Single Vision lenses.

What makes them different: They feature a very subtle, invisible “boost” of extra magnification in the lower portion of the lens. This specific design is engineered to relieve muscle strain when you focus on close-up objects (like smartphones, computers, or books) for extended periods.

How Do They Work?

When you look at something close up for a long time, the muscles inside your eye contract to change the shape of your natural lens so you can focus (a process known as accommodation). Straining these muscles constantly throughout the day while staring at screens leads to digital eye fatigue.

• Traditional Lenses: Provide sharp distance or near vision, but offer zero assistance to your eye muscles during close-up tasks.
• Anti-Fatigue Lenses: Include a very minor optical power increase (known as a boost, usually ranging from +0.40 to +0.80 diopters) at the bottom. This subtle addition lightens the workload on your eye muscles, making close-up focus much more effortless.

 Who Are They For? (Target Audience)

1. Heavy Screen Users: Office workers, programmers, graphic designers, and anyone spending hours in front of computers or digital devices.
2. Teens and Adults (Ages 20–45): Typically prescribed for individuals who do not yet need traditional bifocals or progressive reading lenses, but frequently experience digital strain symptoms.
3. People Experiencing Digital Eye Strain Symptoms: Such as:
   • Dry, tired, or burning eyes.
   • Frequent headaches (especially by the end of the day).
   • Temporary blurriness when shifting focus from near screens to distant objects.
   • Neck and shoulder stiffness caused by leaning forward toward screens.

Key Benefits

• Noticeable Visual Comfort: Drastically reduces the heavy, exhausted feeling in your eyes by the end of a workday.
• Completely Natural Vision: The transition between distance and near vision is seamless with no visible lines on the lens (unlike traditional older adult multifocals).
• Comprehensive Protection: These lenses are frequently paired with Anti-Reflective and Blue Light-blocking coatings to maximize digital comfort.
