Can patients with keratitis use mobile phones?

Keratitis is a common ophthalmic condition clinically, primarily caused by bacterial or viral infection of the cornea. Keratitis can cause white opacities in the normally transparent cornea, obstructing light entry into the eye; patients typically present with blurred vision, and severe cases may lead to blindness. So, can individuals with keratitis use smartphones?

Can individuals with keratitis use smartphones?

Individuals with keratitis should avoid using smartphones. Keratitis episodes cause damage to the corneal epithelium, increasing the sensitivity of ocular surface trigeminal nerve endings and resulting in prominent clinical symptoms of ocular surface disease—including dryness, foreign-body sensation, decreased visual acuity, and blurred vision—thereby contraindicating smartphone use. Smartphone usage further exacerbates visual fatigue, leading to conjunctival hyperemia and edema, which will worsen the underlying keratitis. Therefore, during active keratitis, patients must rest their eyes—keeping them closed as much as possible—and seek prompt medical treatment, including anti-inflammatory agents, microcirculation-improving drugs, antimicrobials or antivirals (as appropriate), and ocular surface lubricants.

If diagnosed with keratitis, patients should avoid spicy foods such as mustard, cinnamon, pepper, ginger, garlic, vinegar, etc., and also refrain from consuming “heat-inducing” meats—including sow, venison, horse, donkey, and mutton. Instead, patients should incorporate into their daily diet foods rich in vitamins, dietary fiber, and easily digestible nutrients. Additionally, foods with heat-clearing and vision-brightening properties—such as apples, bitter melon, lotus root, sugarcane, bananas, and watermelon—are recommended. Vitamin A supplementation is also important; good sources include carrots, spinach, Chinese chives, and other green leafy vegetables. Citrus fruits (e.g., oranges) and persimmons are likewise rich in vitamin A.

Upon noticing symptoms suggestive of keratitis, patients should promptly visit a reputable hospital for professional evaluation and management. We hope this information proves helpful.
