The problem also extends to every light in your house though, not just computer screen.
Ideally, you'd turn off all lights closer to bedtime.
Other things to improve sleep: ideal temperature is around 60-70F, although I go 68-72F. Somewhat colder bodies are easier to slip into sleep and deeper sleep.
Continuous sleep is also obviously ideal; so wear earplugs if noise is issue.
