It may be contact lens
Welcome to health care magic
I am Dr Dadapeer K an ophthalmologist and I answer health problems related to eye.
It seems from the history that you are wearing contact lenses and having dryness and itching of eyes more in left eye.
These symptoms are probably related to use of contact lenses.
The treatment is by using lubricating eye drops. The lubricating drops without preservatives can be used over contact lenses.
You also need to get examination by ophthalmologist to look for the underlying cause for your symptoms in the form of contact lens induced allergy or dry eyes
and need to reduce the wearing time of contact lenses or need to replace the contact lensesas per the advice of your doctor.
Hope the information is helpful to you.
