Is HOYA really an eyeglass company?

HOYA is easy to associate with eyeglass lenses.

That image is still substantially correct.

But the full company looks different once its revenue is split into its two businesses.

First, revenue is ¥947.7 billion

How much of that still comes from the world of vision and medical care?

Life Care 62%, Information Technology 38%

Revenue mix

Life Care62%Information Technology38%

So it would be wrong to say HOYA has simply left eyeglasses behind.

Eyeglass lenses are still No. 2 globally

Then why are semiconductors and HDDs inside the same company?

The answer becomes clearer if we go one step earlier than eyeglasses.

The origin was optical glass in 1941

The timeline then splits in two directions.

Just 12 years after eyeglass lenses, HOYA entered semiconductor substrates

1962Eyeglass lenses

1974Semiconductor substrates

1987Intraocular lenses

1991HDD glass

Today, AI demand is providing a tailwind to the Information Technology side of that history.

HOYA’s mask blanks sit upstream of AI semiconductors

AI infrastructure also needs somewhere to store enormous volumes of data.

In HDD glass substrates, a 100% figure appears

The company has decided to expand both businesses at once.

Phase 1 investment in EUV and HDD totals about ¥92 billion

Why does HOYA choose markets that look so different from one another?

Its Integrated Report describes the selection process itself as a source of strength.

It prefers markets where customers cannot switch suppliers easily

That market selection is reinforced by a combination of capabilities rather than one isolated technology.

HOYA describes the business structure itself as a barrier to entry

Seen this way, the question is not whether HOYA is an eyeglass company or a semiconductor company.

Eyeglasses, medical devices, semiconductor materials and HDD substrates are different destinations for capabilities that began with optical glass and were repeatedly placed in specialized markets.

THE VIEW AFTER THE NUMBERS

What the numbers suggest

Connecting the numbers makes HOYA look less like an eyeglass company that later became a semiconductor company and more like a company that keeps placing optical-glass capabilities in high-barrier niches.

Revenue for the year ended March 2026 was ¥947.7 billion. Life Care still represented 62%, and HOYA says its eyeglass lenses rank No. 2 globally. At the same time, Information Technology contributed 38%, including leading-edge EUV mask blanks and HDD glass substrates. HOYA plans roughly ¥92 billion of Phase 1 investment in new capacity for those two products.

The connecting idea is market structure, not product labels. HOYA says it prefers demanding markets that require close technical alignment and become difficult for customers to switch once a supplier is adopted. The optical glass that started the company in 1941 now connects eyeglasses and intraocular lenses to AI semiconductors and data-center storage.
