BluKaSa Bluetooth Audio Smart Glasses — Polarized UV400

BluKaSa Bluetooth Audio Smart Glasses combine polarized UV400 lenses with open‑ear speakers, hands‑free calling, voice assistant control and IP55 splash resistance for active outdoor use.

These smart sports sunglasses merge eyewear protection and wearable audio into a single lightweight frame built for cyclists, runners, drivers and outdoor enthusiasts. Using Bluetooth 5.3, the glasses maintain a reliable wireless link up to about 20 meters, while the polarized lenses reduce glare and block UVA/UVB. The design emphasizes all‑day comfort — TR90 material, adjustable nose pads and up to 8–10 hours of battery life — so you can stay connected on the move without holding a phone.

How do these glasses handle calls, music and voice control?

The BluKaSa smart glasses use open‑ear speakers and a dual‑microphone system with noise reduction to deliver clear voice calls while keeping ambient awareness. A single multifunction button controls power and playback, and a triple press summons your phone’s voice assistant so you can get directions or send messages hands‑free.

• One‑button operation: single press power/play, double press next track, triple press voice assistant
• Open‑ear speakers let you hear surroundings while listening to audio
• Dual‑mic noise reduction optimizes speech clarity in noisy environments
• Bluetooth 5.3 provides faster pairing and a stable connection up to ~20m

Are the lenses suitable for outdoor sports and bright sunlight?

Yes — the lenses are polarized and rated UV400 to reduce glare and shield eyes from UVA and UVB rays. That makes them suitable for activities where reflective glare is common, such as cycling near water, running on sunlit roads, or driving in bright conditions.

• Polarized lenses cut horizontal glare for improved contrast
• UV400 protection blocks harmful UVA and UVB rays
• Sporty lens shape and wrap help reduce peripheral light intrusion

Will the glasses hold up to sweat, rain and active use?

The frame is made of flexible, impact‑resistant TR90 for durability and light weight during extended wear. Electronics are sealed to an IP55 level, meaning they resist dust and low‑pressure water jets — suitable for sweat, light rain and everyday outdoor exposure, though not for submersion.

• TR90 frame offers strength with low weight and impact resilience
• IP55 rating protects against dust and splashing water
• Adjustable nose pads improve fit for different face shapes

How long does the battery last and how do I charge the glasses?

Battery life supports roughly 8–10 hours of continuous audio playback on a full charge, enough for long training sessions or daily commutes. Charging is simple via the included cable; typical top‑up routines restore full runtime within a few hours depending on the power source.

• 8–10 hours estimated playback per full charge
• Quick‑recharge via included cable for fast turnaround
• Low battery alerts through audio prompts help manage usage

Who is this for: BluKaSa Bluetooth Audio Smart Glasses are built for active people who want sunglass protection and hands‑free audio in one device — cyclists who need road awareness, runners who prefer open‑ear sound, drivers who want voice control, and outdoor hobbyists who need lightweight, durable eyewear with reliable wireless features.
