Mild redness and itching in one eye that worsens during the day may be caused by dryness, allergy, dust exposure, eye strain, or mild surface irritation. Improvement after sleep is common because the eyes remain closed and better lubricated overnight. Although Loteflam eye drops contain Loteprednol, a steroid medicine that can reduce inflammation and itching, it is generally not advisable to restart them on your own without first having an eye examination. Steroid eye drops may temporarily improve symptoms, but if used incorrectly or for too long, they can increase eye pressure, worsen hidden infections, delay healing, and sometimes lead to glaucoma or cataracts. For mild symptoms, lubricating eye drops (artificial tears) are usually safer initial options and may help reduce dryness and irritation. Avoid rubbing your eyes, limit exposure to dust and smoke, and take regular breaks from screens if you use them for long periods. You should consult an eye doctor if the redness persists, spreads, causes pain, discharge, blurred vision, or increased light sensitivity. A proper examination is important to identify the exact cause and decide whether it is safe and appropriate to use steroid eye drops again.
