Thema, the family-owned eyewear manufacturer behind iGREEN Hi-Tech, is launching a new group of collections and clip-on options, according to Giulia Valmassoi, CEO of Thema Optical.
The latest iGREEN 4.0 release is the brand’s lightest collection to date and features several new colors created through Thema’s in-house lamination process. The frames are manufactured at the company’s factory in Miami, allowing Thema to produce on demand rather than through traditional mass production, while also offering a high level of customization.
The company is also expanding its iGREEN PLUS clip-on collection and plans to introduce its first titanium version in September. The update was developed in response to customer demand for titanium temples, particularly for wearers with stronger prescriptions who may benefit from a lighter, more supportive option.
The clip-on offering is also growing, with 10 lens tint options now available. According to Valmassoi, the expanded selection includes non-polarized lenses requested by pilots, alongside a broader range of tints designed for different uses and preferences.
AI-POWERED SALES ANALYSIS IN 2026
Thema introduced its new Smart Sales Report and Smart Board Refresh Report in March 2026, using data generated through its customizable eyewear model to help optical practices better understand what is actually selling in their individual locations.
Valmassoi said most optical boards are still built largely on instinct. Frames are selected, placed on the board and often remain there without a clear understanding of which styles are truly earning their space. Over time, that can lead to growing inventory, slower capture and capital tied up in products that may not be performing.

Thema’s reports are designed to take a different approach. They analyze a practice’s complete purchase and sales history and rank the styles currently on the board based on actual performance, including what has sold, how recently a style has reordered and where it sits in its product lifecycle.
From there, the system can recommend which frames to keep, which to return and which new products to introduce. The analysis also looks at color performance, identifying which acetate colors sell best in a particular location and whether those colors are properly represented in the refreshed assortment.
Valmassoi said one limitation of traditional sales analysis is that it can only evaluate the products a practice already decided to stock. It may show whether those choices performed, but it cannot necessarily identify opportunities among styles, colors or sizes the office has never carried.
THEMA’S BROADER DATA SET IS PARTICULARLY USEFUL
Because the company manufactures customized frames based on individual patient orders, Thema can combine a practice’s own sales history with a much larger pool of sales information across styles, colors, sizes and configurations that may never have appeared on that practice’s board.
The company can therefore identify broader selling patterns and compare them with the preferences of patients at a particular location. In some cases, those data points come from customized frames that were sold to patients before the practice itself ever ordered that exact configuration for inventory.
The goal, Valmassoi said, is not simply to optimize what is already on the board, but to identify products the practice may otherwise never have considered and gradually create an assortment that more closely reflects what customers in that specific market actually want to buy.
Several Thema customers are already using the reports as part of their board-review process.
In simple terms, the company is using each practice’s individual sales behavior together with broader market performance to evaluate a much larger product universe and build an assortment tailored to that location, with the goal of improving inventory productivity and maximizing the return on money invested in frames.
THEMA OPTICAL’S COLLECTIONS AND MODEL
Thema was funded in Italy more than 32 years ago and opened a factory in Miami in 2017. The company’s legacy brands include iGreen, iGreen Kids, O-SIX and Giorgio Valmassoi.
Its collections are designed by an Italian team and manufactured in the United States.
MADE TO ORDER, WITH MIAMI AS THE ADVANTAGE
A core part of Thema Optical’s model is its made-to-order production. Rather than asking optical practices to buy large amounts of inventory up front and hope the styles sell, the company positions its product as a fit set that can be customized once a patient chooses a frame.

The possibilities are extensive. With more than 246 styles in the iGreen collection alone, along with more than 500 frame-front color options, 32 temple colors, multiple temple lengths and customizable hardware, Thema Optical said a single style can generate an enormous number of possible configurations.
That range of customization is also what provides the underlying data for Thema’s sales-analysis tools. Each custom order gives the company additional information about which shapes, colors, sizes and combinations patients are actually choosing, allowing the company to compare an individual office’s sales with a much broader universe of consumer preferences.
AVAILABLE ONLY AT AUTHORIZED DEALERS
Thema’s products are not sold online and are available only through authorized dealers, keeping the optical office at the center of the process. Its AI-powered configurator allows patients to design a frame before visiting the office, then bring that selection to the optician for final guidance and ordering.
Valmassoi said the approach helps reduce the financial risk for practices. Instead of carrying only what was selected in advance, offices can present a smaller opening assortment and then order the exact style, size and color a patient wants.
The company says the benefit is twofold: practices are not locked into excess inventory, and patients are less likely to be limited by what happens to be on hand.
Valmassoi said the U.S.-based factory gives the company a faster turnaround time, with custom pieces delivered in about five business days. That speed matters in an era when consumers expect quick fulfillment, she said. Being manufactured in the United States also helps the company reduce exposure to tariff-related issues.
GETTING STARTED
Practices can start small, then expand based on what sells in their own market. Valmassoi said the opening order typically starts around 30 pieces, though smaller assortments are available for some segments such as kids or Clip-Ons.
Products can be sold as-is off the shelf or customized later with different sizes, colors, temple lengths and nose pads.
It is a model that gives patients the opportunity to select exactly what they want while keeping them connected to their doctor’s office rather than directing the transaction to an online checkout.
