Analog Ultrasonic Cleaner with 1.5V Battery Operation for Glasses and Contact Lenses

This analog ultrasonic cleaner measures 17x6x8cm and operates on two 1.5V No.7 batteries, providing portable cleaning power for eyewear maintenance. The ultrasound technology generates microscopic bubbles through water molecule explosion bursts, effectively stripping oil stains, sweat residue, and surface proteins from both glasses frames and contact lenses. With a dedicated contact lens box compartment and four suction cup base for stability, this plastic-constructed unit delivers cleaning performance several times stronger than manual washing methods, preventing lens graying and maintaining optical clarity through regular 2-3 times weekly use.

Ultrasonic Cleaning Features and Quality Construction

The SD-280 model incorporates specific technical elements that ensure reliable performance during eyewear cleaning sessions, from the battery-powered operation to the suction cup stabilization system that prevents movement during ultrasonic cycles.

Compact Plastic Housing Design

Measuring 17cm in length, 6cm in width, and 8cm in height, the plastic construction provides a lightweight yet durable housing that contains the ultrasonic components. The four suction cups integrated into the base create secure adhesion to smooth flat surfaces, preventing displacement during the 5-minute vibration cycles that characterize the cleaning process.

Battery-Powered Ultrasonic Technology

Operating on 1.5V input voltage from two No.7 batteries, the ultrasonic mechanism produces high-frequency vibrations that generate microscopic bubbles in cleaning solutions. These bubbles undergo rapid expansion and collapse through water molecule explosion bursts, creating mechanical scrubbing action that removes oil stains from glasses and surface proteins from contact lenses without abrasive contact.

Sturdy Construction and Components

The plastic material construction ensures impact resistance during regular use, while the internal components maintain consistent ultrasonic output throughout the 5-minute operational cycles. The dedicated contact lens box fits securely within the main unit, designed to hold care solution at precisely 70% capacity for optimal lens immersion without overflow risk.

Practical Eyewear Cleaning Applications

This ultrasonic cleaner addresses specific maintenance needs for various types of eyewear, from daily wear glasses to specialized contact lenses, providing consistent cleaning performance through regular weekly sessions.

Professional Optical Maintenance Use

Opticians and eyewear retailers can utilize this unit for demonstrating proper cleaning techniques to customers, showing how ultrasonic action removes embedded oils and residues from frame hinges and lens surfaces. The 5-minute cycle efficiently cleans multiple pairs of glasses sequentially, with the suction cup base ensuring stable operation on counter surfaces during customer consultations.

Everyday Personal Eyewear Care

Individuals wearing prescription glasses benefit from regular 2-3 times weekly cleaning sessions that remove accumulated skin oils from nose pads and sweat residues from frames. The ultrasound action reaches into small crevices around screw assemblies and hinge mechanisms where manual cleaning often proves ineffective, maintaining frame hygiene and preventing skin irritation.

Contact Lens Maintenance Versatility

Contact lens wearers achieve several times stronger cleaning than manual rubbing methods, with the ultrasonic action effectively removing protein deposits that cloud vision and reduce lens comfort. The dedicated box holds lenses securely during the 1-2 minute recommended cleaning cycles, positioned centrally to avoid damage from vibration contact with box edges.

Measurable Cleaning Benefits and Value

Regular use of this ultrasonic cleaner provides specific advantages for eyewear maintenance, from immediate visual improvement to long-term preservation of optical investments.

Cost-Effective Eyewear Maintenance

Replacing manual cleaning cloths and solutions with ultrasonic technology reduces ongoing maintenance costs, while preventing scratches that necessitate premature lens replacement. The battery-powered operation consumes minimal energy compared to plug-in models, with the 1.5V requirement providing approximately 30-40 cleaning cycles per battery set based on typical 5-minute usage.

Enhanced Visual Clarity Satisfaction

Users experience noticeably clearer vision as ultrasound removes microscopic residues that manual cleaning misses, with lenses no longer appearing gray from accumulated proteins and oils. The consistent cleaning performance maintains optical quality between professional adjustments, particularly beneficial for progressive lenses and anti-reflective coatings that show smudges prominently.

Convenient Home Cleaning Solution

The compact 17x6x8cm dimensions make this ultrasonic cleaner easily stored in bathroom cabinets or on vanity tops, ready for quick 5-minute cleaning sessions that fit into morning or evening routines. Removing batteries when not in use preserves power for unexpected cleaning needs, ensuring the unit remains operational throughout its service life.
