Reading glasses with +2.50 magnification

These Gunnar Phenom reading glasses provide +2.50 dioptre magnification for near-vision tasks. The amber-tinted lenses filter 65 percent of blue light and block 100 percent of UV radiation. Unisex Onyx frames suit a variety of face shapes. They are designed for people who spend long periods reading printed or digital text.

Thermals noise and power draw

As passive eyewear the glasses generate no heat, produce no audible noise and draw no electrical power. The lightweight aluminium-magnesium frame weighs 21 grams and distributes mass evenly across the nose and temples. Soft thermoplastic rubber temple tips and adjustable floating nose pads reduce pressure points during extended wear.

Magnification strength decides fit

The single specification that determines suitability is the fixed +2.50 dioptre lens power. This magnification level is intended for users who require that exact correction for close-up work. Buyers who need a different dioptre value or variable focus will not be served by this model. The package includes a microfibre pouch and cleaning cloth.

Questions about this item

How do I adjust the floating nose pads to fit the 18 mm bridge, and what step do people skip?

Gently bend each pad inward or outward until the 55 mm lenses sit level; the step most people skip is checking the alignment with the frame's 135 mm width while wearing them.

What maintenance will the micro-engineered lens locks and spring hinges need over time?

Tighten the hidden spring hinge screws annually and clean the lens locks with the included microfiber cloth to prevent debris from affecting the flexible locking mechanism.

At what point does the 65% blue light filtration stop being effective during long sessions?

The 65% blue light filtration and 100% UV protection are constant material properties; they do not degrade or stop being effective regardless of session length.
