Without Frame X-ray Protection Glasses with 5.5 G/cm³ Density and 85% - 95%

Radiology and nuclear medicine technologists spend 6–8 hours daily viewing patients through lead glass. Poor optical quality causes eye strain, headaches, and even positioning errors that increase repeat exposures.

Jovvi lead glass is engineered with human factors in mind:

All panels are tested on a visual inspection light box (10,000 lux) to ensure no distracting striae or bubble clusters. Nuclear medicine grades receive additional color consistency certification – important when comparing whole‑body bone scans across multiple glass panels in a corridor.

Different work settings demand different visual priorities.

• Challenge: Technologists view high‑resolution monitors through glass while scrolling through 1,000+ slices per study.

• Jovvi solution: Anti‑reflection (AR) coating on control room side. Reduces glare from monitor backlighting.

• Ergonomic benefit: 40% less reported eye fatigue (based on Jovvi user survey, n=87).

• Challenge: Patients may move during 20–40 minute scans. Glass must allow clear view of arms, breathing, and IV lines.

• Jovvi solution: Maximum light transmission (84% for 2.5 mm Pb) + neutral tint (no blue or yellow cast that could mask cyanosis or jaundice).

• Ergonomic benefit: Quick detection of patient motion → fewer repeat scans.

• Challenge: Staff may stand for 1–4 hours looking through glass at a steep angle.

• Jovvi solution: Wide viewing angle – transmission drops <10% at 45° off‑axis (industry typical: 20–30% drop).

• Ergonomic benefit: No need to reposition body to see clearly; reduces musculoskeletal strain.

• Challenge: Reading syringe graduations (0.01 mL marks) through glass while drawing radiopharmaceuticals.

• Jovvi solution: Bubble‑free zone in central viewing area (250 mm diameter circle with zero bubbles >0.2 mm).

• Ergonomic benefit: Reduced dosing errors and hand fatigue from leaning around the glass.

• Challenge: Long periods of observation (nurse sits outside for hours). Glass must not distort patient’s face for mental status assessment.

• Jovvi solution: Optical grade flatness (no waviness) – same standard as museum display glass.

• Ergonomic benefit: Accurate assessment of patient distress, airway obstruction, or seizure activity.

Jovvi is one of the few lead glass manufacturers that provides quantified ergonomic data with each panel:

Standard ergonomic report (included at no cost):

• Distortion measurement (arcminutes) at 9 grid points

• Visible light transmittance (380–780 nm) at normal and 45° incidence

• Color rendering index (CRI) – typically 92–94 (excellent)

• Reflection curve (400–700 nm) showing peak reflectivity

Optional AR coating certification (additional cost):

• Reflectivity <1% at 550 nm

• Abrasion resistance (500 cycles steel wool, no visible wear)

• Cleaning chemical resistance (100 wipes with 70% isopropyl alcohol, no coating degradation)

Anti‑glare vs. anti‑reflection – what Jovvi recommends:

Even the best glass can cause eye strain if installed incorrectly.

Jovvi recommended installation practices for ergonomics:

1. Monitor placement: Position monitors so they are parallel to glass (not angled). Angled monitors cause asymmetric reflections.

2. Lighting control: Avoid direct overhead fixtures directly behind the viewer (creates reflection of viewer’s own face). Use baffled or indirect lighting.

3. Viewing distance: Optimal is 60–120 cm from glass. Closer than 45 cm, minor bubbles become distracting; farther than 2 m, detail is lost.

4. Cleaning schedule: Wipe both sides weekly with microfiber cloth. Fingerprints on AR coating are more visible than on standard glass – Jovvi includes specialized cleaning wipes with AR‑coated panels.

5. Frame color: Use matte black or dark gray frame inside control room. Shiny silver frames create edge reflections visible in glass.

“The old glass had a wavy distortion that made me nauseous after an hour. Jovvi glass is like looking through clear air.” – CT Technologist, Florida, USA

“We upgraded three SPECT rooms. My staff stopped complaining about headaches within two weeks.” – Nuclear Medicine Manager, Ontario, Canada

“The anti‑reflection coating is a game changer. I can see my PET/CT fusion screen perfectly without closing the blinds.” – PET Technologist, Melbourne, Australia

“Drawing up Tc‑99m through the Jovvi port is finally easy. I don’t have to lean sideways anymore.” – Radiopharmacist, London, UK
