Why Light Blocking Matters
Light is the primary suppressor of melatonin. Even through closed eyelids, sufficient light intensity reaches the retina and signals the suprachiasmatic nucleus — your circadian master clock — to reduce melatonin output. Street lights, alarm clocks, standby LEDs, and early morning sun all contribute.
A well-fitted sleep mask eliminates these signals entirely, which is why they produce measurable improvements in melatonin levels even when used in already-dim environments.
What We Tested
We evaluated 7 sleep masks on four criteria: light blocking completeness (tested with a lux meter at the mask perimeter), pressure on eyelids, tendency to shift during the night (tested by side sleepers specifically), and ease of removal at 3am without fully waking.
Our Top Picks
1. Alaska Bear Natural Silk Sleep Mask — Best Overall
The most popular mask in this category for good reason. The natural silk surface is gentle on skin and does not absorb as much face oil as synthetic alternatives. The single elastic band distributes pressure evenly. Light leakage is low at the nose bridge with the adjustment done correctly. Side sleepers report minimal shifting. $10–12.
2. Manta Sleep Mask — Best for Light Sensitivity
Contoured eye cups that float over the eyes without contact, adjustable nose bridge, and a modular design that adapts to different face shapes. The best complete light blocker we tested — nearly zero leakage when fitted. The eye cups add some bulk, which some side sleepers find awkward on firm pillows. $35.
3. TEMPUR-Cloud Sleep Mask — Best for Pressure Sensitivity
Uses Tempur material in the eye cup padding for a conformed, pressure-free fit. Heavier than silk options but significantly better for people who find standard masks uncomfortable. Light blocking is good but slightly less complete than the Manta at the cheek seal. $25.
4. Slip Silk Sleep Mask — Best for Skin Care
22-momme silk is the most skin-friendly material for people with sensitive skin or those wearing overnight skincare. Light blocking is moderate rather than complete — not the choice if your bedroom has any meaningful light source. $50.
5. Lewis N. Clark Sleep Mask — Best Budget
Under $5, adequate light blocking for dark environments, washable. The elastic degrades faster than premium options and the foam can trap heat, but as a backup or travel option it performs well above its price.
6. Nidra Deep Rest Mask — Best 3D Contour
Raised eye cavities allow the eyes to move freely during REM sleep, which some users find more comfortable during dream phases. Good light blocking. The foam structure is less packable than silk options. $12.
7. Bucky 40 Blinks Mask — Best for Travel
Ultra-lightweight, packs flat, and blocks light adequately. The molded eye cups provide some REM space. Less effective for home use because the lightweight construction allows more edge leakage. $20.
Pairing With Your Sleep Environment
A sleep mask works best when the other light sources in your bedroom are already minimized. Cover standby lights, use blackout curtains if you have early morning sun, and set your phone face-down. See our full guide to the ideal bedroom environment for a complete checklist.
If noise is also a factor alongside light, consider pairing with earplugs for a complete sensory environment.

Frequently Asked Questions
Do sleep masks actually improve sleep quality?
Yes, for most people in light-polluted environments. A 2017 study in Critical Care Medicine found that patients using sleep masks had higher melatonin levels, less REM disruption, and better subjective sleep quality than controls. The effect is strongest if you have any ambient light in your bedroom.
What is the best sleep mask for side sleepers?
Side sleepers need a contoured or 3D mask that does not flatten against the eyes when pressing against a pillow. The Alaska Bear Natural Silk mask and contoured foam masks with molded eye cups are the most commonly recommended options.
Are sleep masks safe to use every night?
Yes. There are no documented negative effects of nightly sleep mask use. Clean the mask weekly to prevent eye irritation from oil and bacteria buildup.
What NRR rating do I need for a sleep mask that blocks all light?
Sleep masks are not rated by NRR (that is for earplugs). What matters is the seal around the nose bridge and cheeks. A contoured mask with adjustable nose bridge blocks significantly more light than a flat fabric mask at the edges.
Can a sleep mask cause puffy eyes or pressure headaches?
Elastic bands that are too tight around the head can cause morning headaches. Masks that press directly on the eyes can cause temporary pressure marks. Contoured eye cups and wide adjustable elastic bands prevent both issues.
