Choosing the best lens for Focus
Your eyes constantly engage both extraocular and intraocular ciliary muscles to keep your screen sharp.
Hours of continuous screen time push those muscles to their limit — leading to fatigue, headaches, and blurred vision.
GUNNAR's patented focusing power gives those muscles the relief they need, so you can stay focused without the strain.
Natural Focus
Zero accommodative power. The right choice for young eyes still developing, mild myopes with negative prescriptions, or anyone who needs clear distance vision outdoors.
Gunnar Focus +0.2
A subtle accommodative boost that takes the load off your eye muscles during long screen sessions. Designed for adults with 20/20 vision — including contact lens wearers and post-LASIK patients.
