Why do my contact lenses feel uncomfortable by evening?
Usually because the eye is drier by then. Blinking rate falls during screen work, air conditioning dries the surface, and a lens that fits well on a moist eye can feel gritty on a dry one. A drier eye at night is the pattern, not the lens deteriorating during the day.

In more detail
The practical fixes are the ones that change the surface: lubricant drops suitable for lens wear, shorter wearing days, and a review of the lens material and fit. If discomfort is new and one-sided, that is worth an examination rather than an adjustment.
What this answer depends on
- How many hours you wear them
- Whether you work in air conditioning or on screens
- Whether the lens is near the end of its replacement cycle
