What is meant by blepharitis?
Blepharitis (blef-uh-RYE-tis) is inflammation of the eyelids. Blepharitis usually affects both eyes along the edges of the eyelids. Blepharitis commonly occurs when tiny oil glands near the base of the eyelashes become clogged, causing irritation and redness. Several diseases and conditions can cause blepharitis.
What is blepharitis and what are the symptoms?
Blepharitis is a common eye condition that makes your eyelids red, swollen, irritated, and itchy. It can cause crusty dandruff-like flakes on your eyelashes. Blepharitis can be uncomfortable. But it isn’t contagious, and it usually doesn’t cause any lasting damage to your eyes.
Will blepharitis go away on its own?
While blepharitis does not usually go away and there is no cure, the condition is easily maintained by practicing regular eyelid hygiene. It is important for patients to know that left untreated, blepharitis can lead to worse infections and further complications.
Can you go blind from blepharitis?
Blepharitis usually affects both eyes. In some cases it can only affect one eye, but this is uncommon. Once blepharitis occurs, it’s possible to also get a secondary infection. Though uncomfortable, most cases aren’t contagious and won’t cause blindness.
What causes seborrheic blepharitis?
Anterior blepharitis is commonly caused by bacteria (staphylococcal blepharitis) or dandruff of the scalp and eyebrows (seborrheic blepharitis). These bacteria are commonly found on the face and lids, but if they become excessive, or the lid area reacts poorly to their presence, an infection may occur.
Is blepharitis a lifelong?
Is blepharitis a life-long condition? No. The disorder tends to wax and wane and in most patients does not tend to last – in its most severe form – for more than a few months.
Can blepharitis be serious?
Blepharitis causes red, swollen and itchy eyelids. It can normally be treated by washing your eyelids every day. The condition is not usually serious, but can lead to other problems, such as dry eyes, cysts and conjunctivitis, especially if it’s not treated.

Who was Georg Cantor and what did he do?
Georg Ferdinand Ludwig Philipp Cantor was a German mathematician. He created set theory, which has become a fundamental theory in mathematics. We’ll start with Set Theory. A set is a group of things, such as a collection of objects or numbers.
What did Georg Cantor mean by infinitely enumerable set?
Georg Cantor introduced the idea of an infinitely enumerable set. He said that a set whose elements can be paired off with the natural numbers. We also define enumerable sets as countable sets, but this might make you confused because when you try to count all natural numbers, you will die around two billion.
When does fn converge to the Cantor function?
Let fn+1 ( x ) = 1/2 + 1/2 × fn(3 x − 2) , when 2/3 ≤ x ≤ 1 . The three definitions are compatible at the end-points 1/3 and 2/3, because fn (0) = 0 and fn (1) = 1 for every n, by induction. One may check that fn converges pointwise to the Cantor function defined above. Furthermore, the convergence is uniform.
