What bacteria causes pink eye?
There are many different types of bacteria that can cause pink eye.
Most bacterial infections are mild, but some can be severe.
Depending on the severity, they are classified as:
Acute Bacterial Conjunctivitis
Acute Bacterial Conjunctivitis is the most common type of bacterial infection.
Bateria Haemophilus Influenzae, Streptococcus Pneumoniae, or Moraxella Catarrhalis can cause it.
Streptococcus Pneumoniae bacteria is the most common reason of Acute Bacterial Conjunctivitis.
They are found in our own skin.

Although the condition is self-limited and resolves within a week or two, you can take antibiotics to shorten the duration of the disease.

Hyperacute Bacterial Conjunctivitis
Hyperacute Bacterial Conjunctivitis is caused by the bacteria Neisseria Gonorrhoeae or Neisseria Meningitidis.
It is a more severe and rare type.
A proper course of action is required to treat this condition to avoid vision loss.
Chronic Bacterial Conjunctivitis
Chronic Bacterial Conjunctivitis often occurs along with Blepharitis lasting at least four weeks.
The main causes are bacteria Staphylococcus aureus or Moraxella Lacunata.
Staphylococcus aureus lives in our respiratory system and is the more common cause of bacterial pink eye.
It can spread through body fluids when someone infected with it coughs or sneezes.
Chronic Conjunctivitis is not self-limited and usually requires antibiotic therapy.
Causes of bacterial pink eye
Bacteria mentioned in the article can infect our eyes in many ways.
In most cases, the bacteria is spread through insects, physical contact or contaminated makeup.
Insects
Insects, such as gnats or flies, can sometimes be annoying in the summertime.
Moreover, these insects can spread diseases such as bacterial infections.
Flies and gnats spread diseases by transporting bacteria from dirty conditions to humans.
A genus of eye gnats, Liohippelates are common in much of North and South America.
They are attracted to mucous membranes in our body, particularly the eyes.
These flies can spread bacteria into the eyes resulting in bacterial Conjunctivitis (pink eye).
Physical contact with infected people
Bacterial Conjunctivitis can spread through physical contact with infected people in many ways.
The infection can occur through hand-to-eye contact, from mother to baby, or through sexual encounters.
It can also spread by contact with an object that has come into contact with an infected person.
Contaminated eye makeup
Eye makeup can sometimes cause an eye infection.
According to the FDA, eye cosmetics have temporarily or permanently blinded people in rare cases.
Bacteria can spread to the eyes from makeup brushes or products, causing the infection.
Eyelashes usually have bacteria on them. When you use the brush on eyelashes or eyelids, the brush can get contaminated with bacteria.Â
The bacteria buildup on the brush leads to contaminated makeup containers. Using them regularly can increase the risk of bacterial infection.
Infection can be serious if the brush scratches your eye.
Also, sharing any makeup products or brushes can increase the possibility of infection.
