Hello

A few months ago out of the blue my mother started to suffer from what it appears as a foreign object feeling and sometimes her vision gets cloudy...No red eyes or itchy or anything elese

We went to a retina specialst and a Ophthalmologist/Lol i forgot

He checked her eyes and said she was fine? Lol

Every bad she had the feeling, sometimes it's worse and sometimes it's low and doesn't bother

Can anyone explain what this can be? Possibly a cataract trying to transform or something

Because if the doctors said she was and she has a problem and she knows it//
What else is there to do?

IMO she needs a specialist who will examine the front, or surface of her eye. That would be a corneal specialist. There are lots of posters here who know about dry eye; it could possibly be that.
Cataracts are painless--just a clouding of the lens.
