Eschenbach Prismatic BINO Comfort High-Power Reading Glasses – 4D to 10D

When ordinary reading glasses are no longer strong enough

The Eschenbach Prismatic BINO Comfort High-Power Reading Glasses are specialized near-vision glasses for people who need considerably more close-up magnification than standard reading glasses can provide.

They are designed for binocular viewing, meaning both eyes can be used together while reading or completing detailed near tasks. Because the magnification is built into the glasses, your hands remain free for books, paperwork, labels, needlework, crafts, model building, inspection and other close-up activities.

These are not ordinary drugstore readers. They combine strong plus-powered lenses with base-in prism, providing a different type of visual support for people who must work at a very short viewing distance.

What does the prism do?

High-powered lenses require the material to be viewed much closer than it would be with ordinary reading glasses. At a very close distance, the eyes normally have to turn inward more sharply to keep the image aligned.

The built-in prism redirects the image to help support binocular viewing at that close range. The lens power provides the magnification; the prism helps the two eyes work together more comfortably while viewing the near object.

For example:

• +4D Lens / 6Δ Prism means the lenses provide +4 diopters of near power, paired with 6 prism diopters.
• +10D Lens / 12Δ Prism provides substantially stronger near power, paired with additional prism support.

The prism number is not an additional reading strength and should not be added to the lens power.

Who are these glasses intended for?

These glasses may be appropriate for someone who:

• Cannot obtain enough close-up magnification from standard reading glasses
• Wants to use both eyes for close viewing
• Needs hands-free magnification for reading or detailed work
• Has previously used or been recommended high-powered prismatic glasses
• Needs a stronger near-vision option without holding a magnifier

These are task-specific close-up glasses. They are not intended for walking, driving, watching television or general room-distance viewing.

Because the available powers are significantly stronger than standard readers, shoppers who are uncertain about their required power should obtain guidance from an eye-care or low-vision professional before ordering.

Understanding the power choices

Choose from five lens-power and prism combinations:

• +4D Lens with 6Δ Base-In Prism
• +5D Lens with 7Δ Base-In Prism
• +6D Lens with 8Δ Base-In Prism
• +8D Lens with 10Δ Base-In Prism
• +10D Lens with 12Δ Base-In Prism

Stronger lens powers are intended for increasingly close viewing. The best choice is not necessarily the strongest option—it is the power that matches the user’s vision needs, preferred working distance and intended task.

Unlike lower-cost plastic prismatic glasses, the Eschenbach BINO Comfort combines precision CR-39 lenses with a durable gold-tone metal half-eye frame, adjustable nose pads and spring-hinged temples. It is designed for people who need a more refined, comfortable and long-lasting high-power viewing option for regular close-up use.

Comfortable half-eye frame

The gold-tone half-eye frame has adjustable nose pads and spring-hinged temples for a more adaptable fit. Its compact lens shape is designed specifically for concentrated close-up use rather than full-time general vision.

A protective hard-shell case is included for storage and travel.
