Roughly where steel starts to melt, as his beams do on the page and on screen. How hot heat vision really runs is still being researched. ◇

The short answer

Superman's heat vision lets him fire beams of intense heat from his eyes, using the yellow-sun energy stored in his cells. It first appeared in Superman #59 (1949), when he melted a glacier with his eyes, but at the time it was treated as a stronger form of X-ray vision. It was first named as a power of its own in April 1961, in Action Comics #275 and Superboy #88. DC has never given an official temperature.

In depth

The full story.

Heat vision is Superman’s most dramatic power: beams of heat fired from his eyes. It’s also one of his oldest “vision” powers, and it started life as a side effect of something else.

How does Superman’s heat vision work?

Superman’s heat vision focuses the solar energy stored in his cells and fires it out through his eyes as beams of heat. Because it draws on the same reserve as his other powers, heavy use tires him, and it stops working when his powers are gone, under a red sun or near green kryptonite.

How did heat vision begin?

Heat vision grew out of X-ray vision. In Superman #59 (1949), Superman’s X-ray vision fails him and he melts a glacier with his eyes instead. The comic presented this as an especially strong X-ray, not a new ability. For years after that, the comics talked about “the heat of my X-ray vision”. Heat vision was first named as a power of its own in spring 1961, in Action Comics #275 and Superboy #88 (both April 1961). The Superman title caught up in Superman #148 (October 1961). You may read that it was named in Superman #145; an issue-by-issue check doesn’t support that.

What are the limits of Superman’s heat vision?

Energy: every blast spends stored sunlight.
Control: it’s hard to control for a young or emotional Kryptonian. Rebirth comics show Jon Kent struggling with it, and Man of Steel (2013) shows a stressed Clark losing control.
Power loss: red sunlight, green kryptonite and magic shut it down along with his other abilities.

How hot is Superman’s heat vision? (myth-buster)

DC has never given an official temperature. The numbers that circulate online, such as 5,000 °C on a fan wiki or “5.5 million degrees” on quote and FAQ sites, are fan estimates, not facts from a comic or an official guide. The honest answer is to judge by feats: in Superman #59 (1949) his eyes melt a glacier, and in most stories his heat vision is as hot as the story needs.

Heat vision on screen

Heat vision has been a staple of Superman films since Superman: The Movie (1978). Man of Steel (2013) uses it as a sign of Clark’s struggle for control. The exact heat-vision scenes in Superman (2025) are still to be confirmed, so we’ll add them after a rewatch.

A practical use: shaving

How does a man with unbreakable hair shave? One answer the comics have given is heat vision: Superman #139 (1960) is cited for it. Another is a mirror made from his rocket, reflecting his heat vision back, in The Man of Steel #4 (1986). Both come from secondary sources we rate as likely rather than confirmed.

Era by era.

The same Superman, rewritten for every generation.

Golden Age (1938–1956)

Superman #59 (1949): Superman melts a glacier with his eyes after his X-ray vision fails. The comic treats it as a more powerful X-ray, not a new power.

Silver Age (1956–1970)

Heat vision is first named as its own power in April 1961, in Action Comics #275 and Superboy #88. The Superman title catches up in Superman #148 (October 1961).

Post-Crisis (1986–2011)

A standard part of his power set, fuelled by stored solar energy.

Rebirth and today (2016–)

Rebirth stories about Jon Kent show how hard heat vision is to control for a young Kryptonian, especially when emotions run high.

Film and TV

A staple on screen from the 1978 film onwards. Man of Steel (2013) shows it bursting out uncontrolled when Clark is under stress, and Superman (2025) continues the tradition.

Questions.

Where does Superman's heat vision come from?

Superman's heat vision comes from the same place as all his modern powers: energy from Earth's yellow sun, stored in his Kryptonian cells. He focuses that energy and releases it through his eyes as beams of heat. Under a red sun or near green kryptonite, his heat vision fades with his other powers.

When did Superman first use heat vision?

Superman first used heat vision in Superman #59 (1949), melting a glacier with his eyes when his X-ray vision wasn't enough. The comic treated it as a stronger X-ray. It was first called heat vision in April 1961, in Action Comics #275 and Superboy #88.

How hot is Superman's heat vision?

DC has never given an official temperature for Superman's heat vision. Figures you'll see online, such as 5,000 °C or 5.5 million degrees, are fan estimates with no comic behind them. What the comics do show are feats: in Superman #59 (1949) his eyes melt a glacier.

Can Superman control his heat vision?

Usually, yes, but not always. Young Kryptonians struggle with it: Rebirth comics show Jon Kent's heat vision flaring up, and Man of Steel (2013) shows Clark losing control when stressed. Using heat vision also drains his stored solar energy.
