A gritty, sand-like feeling in the eyes without much itching is most often due to dryness rather than active allergy, especially if you spend long hours on screens. While Cromal Forte helps prevent allergic reactions, your current symptoms sound more like dry eye, which can come and go and often returns when treatment is stopped. It is not a good idea to switch to FML Forte on your own, because it is a steroid and repeated use without supervision can lead to side effects like increased eye pressure or infection. The safest long-term approach is to continue lubricating drops regularly (preferably preservative-free), use them more frequently if needed, and make small changes like taking breaks from screens (every 20 minutes, look away for 20 seconds), blinking consciously, and keeping your eyes well hydrated. You can also use a humidifier or avoid direct air from fans or AC. If symptoms still persist, an eye specialist may suggest other options like thicker gels at night or treatment to improve tear quality. With consistent care, dry eye symptoms can be controlled effectively.

Vision problems in one eye can be caused by refractive error, dryness, infection, or issues involving the retina or optic nerve. It is important not to ignore it, especially if the change is recent or worsening. Avoid eye strain, reduce screen time, and protect your eyes from dust and irritation. It would be best to get your eye examined to identify the exact cause and receive appropriate treatment.

A crossed eye is usually due to muscle imbalance or vision issues and often needs proper medical evaluation rather than home treatment. Simple eye exercises may help in mild cases, but they are usually not enough to correct it completely. Early assessment is important, especially to prevent vision problems over time. It is best to consult a doctor to understand the cause and receive appropriate treatment.
