Does a study lamp really reduce eye strain?

Yes, significantly. Eye strain from studying is primarily caused by: insufficient light (eyes strain to focus), uneven light (eyes constantly readjust), harsh overhead light (creates contrast fatigue), and screen-only illumination (dark surroundings create eye stress). A proper study lamp with even coverage, adjustable brightness, and appropriate color temperature addresses all four causes. Students who switch from overhead-only lighting to a dedicated study lamp consistently report reduced headaches, less eye fatigue, and longer comfortable study sessions.

Should I use warm or cool light for studying?

It depends on the time and task. Daytime focused study: 5000-6500K cool white promotes alertness and concentration. This mimics natural daylight and supports sustained attention. Evening study: 3000-4000K warm to neutral white reduces blue light exposure that disrupts circadian rhythm. If you study after 8 PM, warm light protects your ability to fall asleep afterward. Reading for comprehension: neutral 4000K provides comfortable visibility without the intensity of cool white. An adjustable lamp that covers 2700-6500K lets you optimize for every scenario.
