A Stye is an eye condition that causes a painful red lump on the corner of an eyelid. This condition is similar to acne, and generally only affects one eye at a time. A stye usually forms a tiny oil-producing gland in your eyelid skin or eyelash follicle, which becomes blocked causing the eye to be infected. The medical term for a stye is hordeolum. A stye is a very common eye condition and it should clear up by itself within a week or 2. A stye usually only occurs in one eye, but it’s possible to have a stye more than once.
There are two types of stye conditions:
- An ‘external stye’ forms on the outside of your eyelid, either on the lower or upper parts. An external stye is the most commonly seen type of stye and is usually present due to an infection of your eyelash follicle.
- An ‘internal stye’ forms on your inner eyelids. An internal stye generally occurs because of an infection in the inner eyelid gland. This infection produces oils to help keep your eyelid moisturized and this is what causes an internal stye.
Even though styes are common, not all eye infections are styes. It’s unlikely to be a a stye if you don’t have lump on your eye or eyelid. If your eyes are red and watery – conjunctivitis, blepharitis or another condition are more likely. If the lump is not painful but hard, it may be chalazion.
Like other allergies, hay fever can be hereditary. This means you may develop hay fever if members of your family also have allergies. It is also common for people with asthma or eczema to develop hay fever. Hay fever may result in immune system attacks from a harmless and typical substance within the environment.
