If a soft contact lens wearer experiences burning as the day progresses, what does this usually indicate?

When a soft contact lens wearer experiences burning as the day goes on, this typically signifies that the lens may be too tight. A lens that fits too snugly can restrict the natural movement of the eyelid during blinking, leading to discomfort and a sensation of burning or irritation. This tightness can impair tear exchange beneath the lens, which may cause dryness and exacerbate the burning sensation.

In contrast, a well-fitted lens should allow for adequate movement and tear exchange, resulting in comfort throughout the day. A lens that is too loose might not create sufficient contact with the tear film and could lead to different symptoms, such as excessive movement on the eye or even discomfort due to fluctuations in lens position.

Burning is also not typically associated with needing a lens replacement, which is more likely to present symptoms of significant vision deterioration or visible damage to the lens itself. Therefore, the sensation of burning does point toward the fit of the lens being too tight, making that answer accurate in this context.
