Hello, Welcome to Just Answer
Does it appear like a cyst like swelling in the inner corner of your left eye?
It looks almost like a clear blister on the white area.
Ok. Is it on the white of the eye, between the colored part and its junction with the white of the eye? Is there any associated pain or redness?
Yes. No redness or pain.
The spot grew out from the corner and is larger.
It is likely to be a pinguecula which is a type of conjunctival degeneration.
It is a harmless condition, unlikely to cause any further eye problem but for occasional inflammed pinguecula.
A typical pinguecula looks like this- follow this link to view a picture of a pinguecula
I have had a mild pinguecula, which was yellowish on the white area. It appeared to be more of a adhesion looking spot. This appears like a circular glob, but more clear than yellow. My wife researched a few months ago and said it was caused by allergies and would go away. It hasn't yet.
I will check the site you referenced.
It's not this type of spot. If i look away from my nose the spot is very pronounced and noticeable.
A painless circular glob in that area of the eye is most likely to be a pinguecula or even an early pterygium( also a type of conjunctival degeneration). Any other cause of similar lesion is painful like a nodular episcleritis or scleritis, foreign body granuloma.
I undertand that type of condition only requires treatment if it nears the colored area. Correct?
Yes , a pterygium is treated only if it encroaches the colored area ( cornea).
Thank you for your time.
Since the cause of a pterygium is exposure to UV radiation ( sunlight) , usually photochromatic glasses are used for prevention.
You are welcome.
