Specialty and Occupational Lenses

Three Rivers Optical manufactures several specialty and occupational digital lenses for near and intermediate vision, optimized for work up close and for viewing a screen on a desk. Customization of the lens means that you can provide your patients with more options to perfectly fit their needs.

Computer usage and specialty work in a desktop environment is very common among eyeglass wearers. More and more jobs and hobbies are done with small details, digital screens, and at a desk instead of walking through an open space. This creates a unique demand for specialty eyewear for many people.

We deliver both in-house and brand-name, high-quality office designs. These lenses reduce symptoms associated with extended task-specific use, such as eyestrain, eye fatigue, burning sensation, headaches and/or refocusing difficulties. SEEMORE Endless Screen, Endless Desk, Endless Office and Endless Workplace make selecting the perfect lens easier than ever!

You provide the patient’s manifest prescription and ask them to select their primary working distance in the color-coded office diagram we provide you. Select the lens description that is the same as the color that was chosen and—voilà!—task lenses are simplified. Phenomenal as a second pair when you take advantage of our generous 50% off second pair discount. This means more profits for you, and your patient will love the variety so much that he or she will never settle on just one pair of glasses again. Full side free-form lenses guarantee accuracy, customization, and performance. They’re available in virtually all resin materials. Minimum fitting heights are 18mm and 14mm.

SEEMORE Endless Enert-Eyz 1,2,3

These lenses are accommodative relief single vision lenses that have a small amount of plus power at the bottom of the lens. This helps relieve eye fatigue for students and professionals who read or use digital devices for extended periods of time. As a digital backside lens it’s customized and available all resin materials.

The lenses are fit like progressives and available as a 1, 2 or 3; the plus power boost is +0.50^, +0.75^ and +1.00^ respectively. HEV blue filtering materials are systematically included at no extra charge. Pair with Ultimate Blue Filter UV or See More Prevent UV for full HEV spectrum reduction.

TRO “O” Seg

The TRO “O” seg is the only patented, fully-customized, digitally-surfaced convex-side-lined bifocal on the market. It is a round bifocal with a barely visible, soft narrow line. Perfect for the occasional PAL non-adapt, as an upgrade from a flat top, as a specialty lens (occupational double seg), or as a golf seg (rotating the segment to meet the patient’s need), and is the perfect lens for children requiring an add. Available in any resin material, segment widths from 15mm to 45mm at no extra charge, adds from +0.50 to +5.00. The “O” seg is an excellent customization tool to meet special patient needs.

The TRO “Blended O” seg is the same as the standard “O” seg except that the line is widened to further minimize the appearance of the seg line. Patients who are extremely sensitive to cosmetics will prefer this lens style. Learn more about the TR-O-Seg here.


Shamir Computer/Workspace

Shamir Computer provides a wide field of near and intermediate viewing with clear vision up to 1.5 meters (5 feet). Workspace provides near, intermediate, and clear vision up to 3 meters (10 feet). This is a far greater depth of field than that offered by conventional reading lenses.

These lenses are a great opportunity to offer a pair of task-specific progressives or an upgrade to reading glasses for presbyopes who spend time on desktop or laptop computers.


Unity Office Pro 5/Office Pro 10

Unity Via OfficePro takes the guesswork out of computer lenses, automatically calculating the intermediate and near zones for you. This ensures the monitor stays in the visual sweet spot without any extra measurements. Simply determine the progressive Rx, pick the working distance, and OfficePro does the rest.

Two working distances make it easy to match lens choice with each patient’s workplace needs. OP5 for patients who do computer work, desk work, reading, etc. The OP10 works well for patients doing computer work but also needs clear vision farther away – visitor reception, meetings, etc.
