===Associated symptoms===
* Watery eyes – due to excessive tearing.<ref name="autogenerated12">{{cite web | url = http://www.mayoclinic.org/diseases-conditions/blepharitis/basics/symptoms/con-20024605 | title = Blepharitis Symptoms - Diseases and Conditions | work = Mayo Clinic | access-date = 2015-01-03 | archive-date = 2017-09-22 | archive-url = https://web.archive.org/web/20170922055825/http://www.mayoclinic.org/diseases-conditions/blepharitis/basics/symptoms/con-20024605 | url-status = live }}</ref>
* Red eyes – due to dilated blood vessels on the sclera.<ref name="autogenerated12" />
* Swollen eyelids – due to inflammation.<ref name="autogenerated12" />
* Crusting at the eyelid margins/base of the eyelashes/[[Anatomical terms of location#Medial and lateral|medial]] [[canthus]], generally worse on waking – due to excessive bacterial buildup along the lid margins.<ref name="autogenerated22" /><ref name="Lowry_2019" /><ref name="autogenerated12" />
* Eyelid sticking – due to crusting along the eyelid margin.<ref name="autogenerated12" />
* Eyelid itching – due to the irritation from inflammation and epidermis scaling of the eyelid.<ref name="autogenerated12" />
* Flaking of skin on eyelids – due to tear film suppressed by clogged meibomian glands.<ref name="autogenerated12" />
* Gritty/burning sensation in the eye, or foreign-body sensation – due to crusting from bacteria and clogged oil glands<ref name="autogenerated12" />
* Frequent blinking – due to impaired tear film from clogged oil glands unable to keep tears from evaporating.<ref name="autogenerated12" />
* Light sensitivity/[[photophobia]]<ref name="Lowry_2019" /><ref name="autogenerated12" />
* Misdirected eyelashes that grow abnormally – due to permanent damage to the eyelid margin<ref name="autogenerated12" />
* Eyelash loss – due to excessive buildup of bacteria along the base of the eyelashes.<ref name="autogenerated12" />
* Infection of the eyelash follicle/sebaceous gland ([[hordeolum]])
* Debris in the [[tear film]], seen under magnification (improved contrast with use of [[fluorescein]] drops)

Chronic blepharitis may result in damage of varying severity and, in the worst cases,  may have a negative effect on vision. This can be resolved with a proper [[eyeglass prescription]].<ref name="emedicinehealth2">{{Cite web|url=http://www.emedicinehealth.com/eyelid_inflammation_blepharitis/page3_em.htm#Eyelid%20Inflammation%20Symptoms|title=Eyelid Inflammation Symptoms|vauthors=Weinstock FJ|publisher=emedicinehealth.com|access-date=21 December 2012|archive-date=18 October 2012|archive-url=https://web.archive.org/web/20121018121718/http://www.emedicinehealth.com/eyelid_inflammation_blepharitis/page3_em.htm#Eyelid%20Inflammation%20Symptoms|url-status=live}}</ref> Long-term untreated blepharitis can lead to eyelid scarring, excess tearing, difficulty wearing contact lenses, development of a [[stye]] (an infection near the base of the eyelashes, resulting in a painful lump on the edge of the eyelid) or a [[chalazion]] (a blockage/bacteria infection in a small oil gland at the margin of the eyelid, just behind the eyelashes, leading to a red, swollen eyelid), chronic [[pink eye]] ([[conjunctivitis]]), [[keratitis]], and [[corneal ulcer]] or irritation.<ref name="autogenerated22" /><ref>{{cite web | url = http://www.mayoclinic.org/diseases-conditions/blepharitis/basics/complications/con-20024605 | title = Blepharitis - Diseases and Conditions | work = Mayo Clinic | access-date = 31 October 2023 | archive-date = 10 September 2017 | archive-url = https://web.archive.org/web/20170910122444/http://www.mayoclinic.org/diseases-conditions/blepharitis/basics/complications/con-20024605 | url-status = live }}</ref><ref name="Lowry_2019" /> The lids may become red and may have ulcerate, non-healing areas that may lead to bleeding.<ref name="emedicinehealth2" /> Blepharitis can also cause [[blurred vision]] due to a poor tear film.<ref name="autogenerated22" /> [[Tears]] may be frothy or bubbly, which can contribute to mild scarring along the eyelids. Symptoms and signs of blepharitis are often erroneously ascribed by the patient to "recurrent conjunctivitis".<ref name="Dahl"/>
