What is Blepharitis?

Blepharitis is the inflammation of the eyelids, in which the eyelids become red, itchy and irritated. This is due to the overgrowth of bacteria along the lid margins. It can affect people of all ages. By using a microscope, we can take a photo of your eyelashes to show you the blepharitis. Crusting of the eyelids , also known as “bak sai” or “yan shi” is a common symptom seen in people suffering from blepharitis.  

There are 2 types of blepharitis: 

1) Anterior blepharitis: Occurs at the front surface of the lid margin, at the root of the eyelashes.

2) Posterior blepharitis: Occurs on the inner lid margin that touches the eyeball.  

Eyelash extensions and blepharitis

Knowing the definition of blepharitis helps us to understand why eyelash extensions is a cause of it. Eyelash extensions are being glued onto the eye, thus making it harder to clean them thoroughly. Washing your face every night and using of lid wipe is important as a daily hygiene routine. However, they are unable to ensure that lid hygiene has been maintained, as there are bound to have many small spaces that have been missed out during the cleaning process. This is the chance for bacteria and demodex (mites that lives in our eyelash follicles) to grow, toxins are produced which then causes inflammation of our eyelashes (blepharitis).

What are the symptoms of blepharitis?

  1. Gritty or burning sensation 
  2. Excessive tearing 
  3. Itching, redness, swollen eyelids 
  4. Crusting of the eyelids 
  5. Contact Lens discomfort 

Complications of blepharitis

  1. Misdirection of eyelashes 
  2. Loss of eyelashes 
  3. Keratitis 
  4. Allergies 
  5. Dry Eyes 

Is it contagious?

No, blepharitis is not contagious. However it is a vicious cycle if it is not detected and treated properly. As we grow older, our bodies are unable to make sufficient natural antibodies in our tears, resulting in the overgrowth of normal bacteria on our lid margins. 

Exotoxins and endotoxins are produced by the bacteria, causing inflammation to occur along the lid margins. This inflammation affects our tear glands, causing a decrease in tear and antibodies production, resulting in the increase in growth of bacteria, and the vicious cycle repeats itself. 

Causes of blepharitis

  1. Aterior blepharitis is mostly caused by bacteria (staphylococcus aureus), or overreactive sebaceous glands.
  2. Posterior blepharitis is caused by the irregular secretion of oil from glands in the eyelids known as the meibomian glands. This creates an optimal environment for the bacteria to reproduce and multiply.

What is Demodex?

Demodex is a type of tiny mite that lives in our eyelash follicles. Demodex’s main source of food is the oil secreted by our sebaceous glands.

Research has shown that 44% of blepharitis patients have demodex in their eyelash follicles, with the increase in numbers as we get older. It is therefore important to find and treat the root cause of the problem. 

Here is an animation showing how demodex thrives and affect the health of our lid margins. 

What are the treatments available for blepharitis?


“Blepharitis is a common cause of redness, itchiness and allergies. It is often overlooked. Now, there is BLEPHEX that treats it easily.”

How does BlephEx work?

It is a painless procedure that uses a medical grade micro sponge that spins thoroughly and carefully along your upper and lower lid margins to remove excess bacteriabiofilm and toxins from your lids and lashes. The micro-sponge is disposable and is changed after cleaning each eye to ensure that hygiene is well kept. You will be taught on lid hygiene after the treatment, to prevent blepharitis from occuring. 

Why choose BlephEx? ​

  1. Thoroughly cleans off bacteria and mites (Demodex) that sticks to the eyelashes
  2. More efficient than manual lid hygiene 
  3. Effectively cleans hard to reach areas 
  4. Able to thoroughly remove excess bacteria and scruffs from your eyes
  5. 5 minutes procedure 
  6. Repeated every 6 months 
  7. No down time, you can resume back to work and social activities right after the treatment!
  8. Convenient for people who don’t have time to clean daily

Lid hygiene after BlephEx treatment is still necessary to maintain daily lid cleanliness. 

It is essential to remove the accumulation of bacteria and debris from the lid margins for a successful blepharitis treatment. Therefore, wiping of your eyelids with lid wipes and warm compress should be done daily to reduce the growth of bacteria and demodex (mites that live in our eyelash follicles) from growing on your lids.
