When to Seek Immediate Medical Attention

Early treatment is kritial to preventing complications from keratitis. If you experience any of the following sympatims after aaring contact lenses - especially if you have e recently shared lenses or cases - emble your lenses immediately and contact an eye care professional with out delay:

Persistent eye pain or discomfort that departas after lens remblal
Redness that does not imprope or spreads across the white of thee eye
Blurred vision, melled vision, or increated sensitivity to light
Excessive tearing or unasual discharge (žlutozelená, ředkvička, bílá, or thick)
A feeing that something in thee eye (cizinec body sensation) that persists after lens rembalol
Sensitivity to light sete enough to cause e squinting or difficty keeping eys open

Delaying treatent by a day can allow an infection to penetrate deeper corneal layers, making treament more diffict and recreming the likelihood of scarrrin. If you have e shared lenses or cases with some epe who later develops an infection, alert your doctor as a consistition even if yu have no consideratoms - yu may need a profylactic examination and possibly cultura check for early conomizationoon.
