Tongyi Optical supplies 1.56 index photochromic grey lenses from Shenzhen, China. These lenses darken automatically when exposed to ultraviolet light and return to a clear state indoors, offering a single-lens solution for wearers who move between indoor and outdoor environments. The grey tint provides neutral colour perception, making it a practical choice for daily use across varied lighting conditions.
The 1.56 index keeps the lens relatively thin and light compared to standard 1.50 CR-39, which benefits rimless and semi-rimless frame designs. A scratch-resistant coating is applied to maintain surface clarity through regular handling. The lenses also incorporate UV filtering to protect against harmful ultraviolet rays. Tongyi Optical notes that customisation is available for different prescriptions and frame styles. Minimum order quantities, pricing, and lead times are not listed; buyers should contact Tongyi Optical directly to discuss trade terms, including FOB and CIF shipping options.

Importing 1.56 photochromic lenses from Shenzhen, China, gives buyers access to one of the country's most established eyewear manufacturing regions. Tongyi Optical is based in the Nantian Building in central Shenzhen, a location well connected to the city's port and logistics infrastructure. For buyers sourcing mid-index photochromic lenses in volume, Shenzhen suppliers typically offer competitive lead times on both stock and customised orders.
Before placing a first order, request product samples to verify photochromic activation speed, grey tint neutrality, and scratch-resistance performance. Ask Tongyi Optical for any quality or compliance certificates relevant to your import market, as these are not listed on the current profile. Clarify MOQ, unit pricing, and whether lenses ship as finished pairs or semi-finished blanks, as this affects your downstream processing requirements.
When negotiating trade terms, confirm whether Tongyi Optical ships FOB Shenzhen or offers CIF to your destination port. Secure packaging for optical lenses typically involves individual lens pouches within rigid boxes to prevent transit damage. Discuss packaging specifications and insurance options with the supplier to ensure lenses arrive in sellable condition.
