Three documented strands in DITA's history

DITA dates its founding to 1995 and describes its first collections as vintage-inspired shapes with colored lenses. Its timeline places the Flight-Series in 2002, with a reference to supersonic military aircraft of the 1970s, and the Mach-Series launch with MACH-ONE in 2012, drawing on automotive racing and supercar design.

These references explain different starting points for a design. They are not performance certifications: an aviation influence does not make a pair protective flight equipment, and automotive inspiration does not establish suitability for every driving condition. The history also should not be used to assign an unverified supplier model to a series.

Read the front as a distribution of material

In the DTS 464 catalogue reference image, identified in the image as GRANDMASTER-NINE, a broad black rim encloses each lens. A dip in the upper line leads into the bridge, and two small bright dots punctuate each outer front corner. Much of the visual emphasis sits around the lens openings.

The DTS160 record's ARTOA.92 reference image uses a much thinner perimeter and two separate lines above the nose: the bridge and an upper bar. The lens surface occupies more of the visible front. The contrast is between a substantial enclosing rim and a slender outline, not a verified comparison of grams or comfort.

The side view can change the impression

GRANDMASTER-NINE's official description identifies an oversized three-barrel hinge plate with enamel inlay. Its side reference image makes the elongated bright hinge area much clearer than the frontal image. ARTOA.92's catalogue side image instead shows a fine temple line with a darker inset near the tip.

This gives a practical way to compare a display: inspect front and side separately, then decide whether you want the rim or the connection detail to draw attention. A photograph can support that visual decision. It cannot verify the alloy, the hinge's durability or how the frame feels after several hours of wear.

Use the history to frame a specific buying question

The two catalogue records list 54 / 20 / 145 mm for DTS 464 and 61 / 12 / 145 mm for DTS160. The second has a larger listed lens width but a smaller bridge figure; the equal temple lengths do not establish equal fit. Ask for measured front width and the actual bridge construction before treating either as a size substitute.

Follow the individual design notes below when the question becomes model-specific. The GRANDMASTER-NINE note compares official dimensions with EIGHT; the ARTOA.92 note separates the current 424 collaboration from the supplier record. For an enquiry, keep the SKU, color, quantity and destination together so that design preferences can be translated into a confirmed specification.
