Those symptoms might be due to autumn pollen.

Hello. This is Minami Fnabashi-bayside GANKA.
Do you ever feel like your contact lenses don't suit you as much in the fall, or that your eyes are itchy and you can't concentrate on work?
The cause might actually be hay fever.
While hay fever is often associated with spring, a lot of pollen is also released in the fall. Moreover, hay fever can develop suddenly, so even those who have never experienced symptoms in previous years should not be complacent.
If allergy symptoms are left untreated, inflammation can persist, and eye itching can worsen. Rubbing your eyes due to itching can damage the surface of the eye, further exacerbating the symptoms.
Soft contact lenses, in particular, contain moisture, making them prone to attracting pollen, which can cause discomfort. Therefore, 1-day disposable lenses, which can be replaced daily, are less strenuous on the eyes than lenses that are replaced regularly.
Furthermore, using contact lens solutions to prevent dirt from adhering to the lenses is also an effective measure.
If you're experiencing eye problems this fall, don't just put up with it. Why not get checked out early, including the possibility of hay fever?
