Sleeping with mascara on can cause a multitude of issues for your eyes and eyelashes. The mascara dries and makes your eyelashes feel heavy and brittle, and the stiff lashes can easily break when they rub against your pillowcase. The ingredients in the mascara can also accumulate under your eyelids, and when the cornea is rubbed, scratches can occur. This can lead to eye irritation, redness, and the formation of uncomfortable bumps called styes. Mascara flakes, oils, and bacteria can clog glands and irritate the eyes, and the bacteria build-up can cause eye infections like keratitis.

What You'll Learn
Increased risk of eye infections
Mascara contains a number of waxes, oils, pigments, and emollients. While these components can provide hydration to your lashes and enhance their appearance, the accumulation of chemicals present in the mascara can cause a variety of eye problems.
Sleeping with mascara on can cause eye irritation, infections, and clogged hair follicles, which may result in styes. Mascara can also transfer to your pillow, leading to further contamination and irritation. The ingredients in mascara can also start accumulating under your eyelids. This accumulation of masses, when rubbed against the surface of the cornea, can cause scratches, leading to eye infections.
Bacteria build-up from regularly wearing mascara overnight is often how eye infections, such as keratitis, can develop. Keratitis is an eye infection that occurs when your cornea is irritated, leading to redness, eye pain, watery eyes, blurred vision, and light sensitivity.
Additionally, when you sleep with mascara on, it continues to dry, making your eyelashes feel heavy and brittle. The friction caused by the pillowcase can cause these brittle lashes to fall out.

Scratches on the cornea, conjunctiva, or sclera
Sleeping with mascara on can have adverse effects on the eyes, including scratches on the cornea, conjunctiva, or sclera. The cornea is a thin, transparent layer of tissue on the surface of the eye that is highly sensitive to foreign bodies. When mascara is left on overnight, it dries off and forms solid masses that collect under the eyelids, leading to the formation of concretions. These concretions cause a foreign body sensation in the eye, resulting in an urge to rub the eyes. As the masses accumulate, rubbing them against the surface of the eye can cause scratches to the cornea, conjunctiva, and sclera (the white part of the eye).
The cornea, conjunctiva, and sclera are responsible for protecting the eye and providing vision. When these protective layers are scratched, opportunistic bacteria present on the skin and hands can invade the eye, leading to infections such as keratitis, conjunctivitis, and follicular conjunctivitis. These infections can cause irritation, inflammation, and discomfort, as described by Dr. Rebecca Taylor as "throwing a handful of sand in your eye." In some cases, corneal abrasions, if left untreated, can lead to serious infections and vision problems, including irreversible visual disturbances and, in rare cases, a loss of sight.
The accumulation of mascara masses under the eyelids can also result in hardened bits poking through the conjunctiva and scratching the cornea, as seen in a case study of a woman who suffered severe consequences from repeatedly sleeping with mascara on. The concretions embedded in her conjunctiva caused chronic irritation and discomfort, requiring surgical removal. This case highlights the importance of proper eye hygiene and the removal of mascara before sleeping to prevent scratches and potential infections.
To avoid scratches on the cornea, conjunctiva, or sclera, it is crucial to remove mascara completely before sleeping. This can be achieved by using cleansing face wipes or washing your face with clean hands and water to ensure all traces of mascara are removed from the eyelashes and eyelids. Additionally, it is recommended to replace mascara regularly and choose formulas that are hypoallergenic or ophthalmologist-approved to minimize the risk of irritation and allergic reactions.

Irritation, redness, and bumps on eyelids
Sleeping with mascara on can lead to eye irritation, redness, and bumps on the eyelids, also known as styes. Styes are uncomfortable bumps that form on the eyelids due to clogged hair follicles. The mascara can transfer to your pillow, leading to further contamination and irritation.
The eyes are constantly exposed to bacteria, which can accumulate and cause infections when trapped overnight by mascara. This can lead to eye infections such as keratitis, which is an infection of the cornea that often results in redness, eye pain, watery eyes, blurred vision, and light sensitivity.
Additionally, the mascara can dry and make your eyelashes feel heavy and brittle. The friction caused by rubbing your eyes or sleeping on a pillow can cause the brittle lashes to break and fall out. The dried mascara can also scratch your cornea, conjunctiva, or sclera (the white part of the eye), leading to further eye damage and potential vision issues.
To avoid these issues, it is important to remove your mascara before sleeping. While makeup wipes can help remove some mascara, they may not completely dissolve it, especially if it is waterproof. Therefore, it is recommended to use a makeup remover or cleanser to ensure that all traces of mascara are removed before going to sleep.

Loss of eyelashes
Mascara contains a number of waxes, oils, pigments, and emollients. While these components can provide hydration to your lashes and enhance their appearance, the accumulation of chemicals can cause eye problems.
Sleeping with mascara on can make your eyelashes feel heavy and brittle. The weight of the mascara can cause the lashes to fall off, especially when they rub against a pillowcase. The mascara can also scratch the cornea, conjunctiva, or sclera (the white part of the eye) when the dried mascara rubs against the surface of the eye.
Additionally, the oils and bacteria in the mascara can clog glands and irritate the eyes. This can lead to eye infections and the formation of uncomfortable bumps called styes on the eyelids.
To avoid these issues, it is important to remove mascara before sleeping. While makeup wipes can help remove some mascara, they may not completely dissolve it, and a cleanser or makeup remover may be necessary to ensure all traces are removed.

Clogged glands
Sleeping with mascara on can cause clogged glands and irritate your eyes. During the day, blinking and air circulation help to prevent this. However, when you sleep, mascara flakes, oils, and bacteria can become trapped and settle in the area near the lacrimal openings, causing issues.
Makeup prevents the skin from breathing and healing, leading to an increase in free radicals, which cause inflammation, redness, and dullness. Free radicals also break down collagen, contributing to wrinkles, clogged pores, acne, and blackheads.
Waterproof mascaras, in particular, are harsher on the lashes and more difficult to remove, making them riskier if left on for extended periods. Hardened mascara particles can accumulate along the lash line, leading to inflammation and potential damage to the oil glands that help keep the eyes moisturized.
To prevent clogged glands and other issues, it is important to remove mascara before bed. A proper cleansing routine with gentle, hydrating products can protect your lashes, prevent clogged pores, and support your skin's natural repair process. Oil-based cleansers or micellar water are effective ways to remove mascara gently and thoroughly.
