Reddened eyes what it depends on

Reddened eyes, what does it depend on?

The reddened eyes have different causes: some are related to eye diseases, while others depend on environmental conditions. They are also often caused by too many hours in front of PC screens especially in this period of smart working.

Red eyes often depend on other factors as well.

They can occur, for example, after:

  • having cried a lot
  • Having consumed a lot of alcoholic beverages (since these have a vasodilating effect) or taken drugs
  • Being exposed to a strong wind or for a long time to sunlight

Redness of the eyes can also be due to the presence of a foreign body in the eye or contact with irritants (for example, when soap or shampoo gets into an eye).

Even frequent contact lens wearers can run into the problem of red eyes, which, however, can also be a consequence of a severe cold, flu or a very loud cough.

Often waking up with red eyes even after a sleepless night.

In short, there are several factors that can lead to redness of the eyes and there are also pathological causes that lead to it such as:

  • Conjunctivitis, an inflammation of the mucous membrane covering the periphery of the white part of the eye
  • episcleritis, also an inflammation of the sclera (the white part of the eye)
  • shingles, Another infection caused by the varicella-zoster virus
  • uveitis, an inflammation of the membrane located between the cornea and the sclera
  • high blood pressure
  • Dry eye syndrome (when few tears are produced)
  • blepharitis, inflammation of the ciliary edge of the eyelid
  • keratitis, inflammation of the cornea

More serious diseases, whose symptoms also include red eyes, include:

  • ebola and other hemorrhagic fevers
  • ocular tumors
  • glaucoma
  • trachoma, a type of chronic conjunctivitis that is generated by the bacterium Chlamydia Trachomatis

In any case, to get an accurate diagnosis, the advice is to see a doctor who, also based on any other related symptoms (such as nausea, headache, itching, watery eyes, and so on), will know how to give the most appropriate treatment.
