Bacterial conjunctivitis (conjunctivitis)

Bacterial conjunctivitis is a common type of pink eye, which is caused by bacteria and infects the eye through various sources of contamination.

Viral conjunctivitis (conjunctivitis)

Viral conjunctivitis (conjunctivitis) is another common type of pink eye that tends to be highly contagious because airborne viruses can be spread through sneezing and coughing. Viral conjunctivitis can also occur with common viral upper respiratory infections such as measles, flu, or the common cold.

Viral conjunctivitis usually causes a watery discharge. The infection usually starts in one eye and quickly spreads to the other eye.

Unlike bacterial infections, antibiotics will not work against viruses. No eye drops or ointments are effective against the common viruses that cause viral conjunctivitis. But viral conjunctivitis is self-limiting, which means it will go away on its own after a short period of time.

Usually, with viral conjunctivitis, three to five days are at their worst. After that, the eyes start to improve on their own.

Treatment of viral conjunctivitis usually includes supportive therapies, such as topical eye drops, that help reduce symptoms: eg, vasoconstrictors to whiten the eye, surface Decongestants to reduce inflammation, and topical antihistamines to reduce itching work. Treatment is usually continued for one to two weeks, depending on the severity of the infection.

Allergic conjunctivitis (conjunctivitis)

It is common to have this pink eye caused by an eye allergy. Eye sensitivities, of different sorts, can be set off by allergens including dust, creature dander, and residue parasites.

The most common symptom of allergic conjunctivitis is itchy eyes, which can be relieved with special eye drops containing antihistamines to control allergic reactions.

Staying away from the allergen is likewise significant in the treatment of unfavorably susceptible conjunctivitis. Allergic conjunctivitis can occur seasonally or even during the year, depending on the reaction caused by the allergen.

This pink eye usually affects both eyes and mostly affects those wearing soft contact lenses. This condition can cause contact lens intolerance, itching, heavy discharge, watery eyes, and red bumps under the eyelids.

You will need to stop wearing your contact lenses at least for a while. Your eye doctor may also recommend that you switch to a different type of contact lens to reduce the chances of conjunctivitis coming back.
