Which symptoms indicate a tight fitting lens?

A tight-fitting contact lens can lead to several physiological responses in the eye. Corneal edema is one of the primary symptoms associated with this condition. When a lens is too tight, it can restrict the natural movement of tears and oxygen to the cornea, resulting in swelling of the cornea, or edema. This swelling can cause foggy or blurry vision due to the altered shape and clarity of the cornea.

The combination of corneal edema and compromised vision serves as a clear indicator of a lens that does not fit properly, highlighting the need for regular assessments of lens fit during eye care examinations. Symptoms such as dryness and redness can sometimes occur with poorly fitting lenses, but they are more commonly associated with issues related to insufficient tear exchange or lens material. Increased tear production might suggest irritation or discomfort, but it does not specifically indicate a tight fit in the same way that corneal edema and foggy vision do.

Thus, the presence of corneal edema and foggy vision directly correlates with a tight-fitting lens situation, making this the correct choice in addressing the symptoms indicative of such a fit.
