**Core Concept**
Foreign body in the eye refers to an object that has entered the eye and is causing irritation or damage to the ocular surface. This can be a result of various activities such as accidental trauma, sports, or even self-inflicted injuries. The eye's natural defense mechanisms, including the tear film and eyelid movements, may not be sufficient to remove the foreign object.

**Why the Correct Answer is Right**
The correct answer is related to the management of a foreign body in the eye, specifically the use of irrigation to remove the object. The eye's anterior chamber and conjunctival sac can be irrigated with saline or water to flush out the foreign body. This is usually done under the guidance of an ophthalmologist or emergency physician to avoid further complications such as corneal abrasions or chemical burns.

**Why Each Wrong Option is Incorrect**
**Option A:** This option does not address the management of a foreign body in the eye and is therefore incorrect. Using a contact lens to remove a foreign body may push the object further into the eye, causing more harm.
**Option B:** This option is incorrect because it does not provide a suitable solution for removing a foreign body in the eye. Applying pressure to the eye may cause further damage to the ocular surface or even lead to a retinal detachment.
**Option C:** This option is also incorrect as it is not a suitable method for removing a foreign body in the eye. Using a chemical to dissolve the object may cause chemical burns to the ocular surface.

**Clinical Pearl / High-Yield Fact**
In cases of a foreign body in the eye, it is essential to avoid rubbing the eye or using any sharp objects to remove the object, as this can cause further damage to the ocular surface. Instead, seek medical attention from an ophthalmologist or emergency physician for proper evaluation and management.

**Correct Answer:** B. Flushing the eye with saline or water.
