What does grade 4 indicate?

• A. Not Present
• B. Minimal
• C. Mild
• D. Severe

Answer: (D)

On a typical 0–4 severity scale used for ocular reactions, higher numbers mean worse problems. A grade of four is the most severe level, indicating a severe reaction. This would include pronounced signs and symptoms such as significant pain or discomfort, marked redness, notable discharge, vision changes or light sensitivity, and sometimes corneal involvement. Because it signals a high risk of complications, it usually requires stopping lens wear and prompt, urgent assessment and treatment. The other options describe milder levels: not present means no signs at all, minimal is barely detectable, and mild shows noticeable but not disabling symptoms.
