Hi Sara,
Thanks for your question. From the symptoms you have described you may have suffered a mild chemical
injury or you may have a corneal abrasion (scratch to the clear part of your eye where the
contact lens sits).
You did the right thing washing out your eye immediately as any soap will probably have been washed out. The soap may have injured the front of your cornea and this may be responsible for the
blurred vision.
However, I would be wary of putting all your symptoms down to just a bit of soap on your finger. It may be that you scratched your cornea as you were removing the lens or when you put it back in. This would result in a lot of discomfort, watering and
photophobia (difficulty looking at bright lights).
I'm not sure what type of contract lenses you wear but occasionally leaving your lenses in very concentrated cleaning fluid can also cause irritation of the eye. This will also damage the front part of the cornea so your vision may become blurred.
The most sensible thing to do is to avoid wearing your contact lenses until you have been seen by an eye doctor and anything too serious such as an infection has been ruled out. Also when you go to see them it would be useful if you take your cleaning fluid and contact lenses with you as they may decide to send these off to the lab for analysis.
Provided it is just a simple abrasion or a mild chemical injury you doctor may prescribe you some antibiotic ointment to prevent any secondary infection.
Once again I would recommend that you see your eye doctor as soon as possible for a thorough examination of the front your eye.
Regards
