borrosa

Borrosa is the feminine form of the Spanish adjective borroso, used to describe something that lacks sharpness or clarity. In English, it is commonly translated as blurred or fuzzy. The word is applied to images, vision, or any perception that is not clearly defined.

In everyday language, phrases such as visión borrosa or imagen borrosa indicate a lack of clarity in sight or representation. The term appears across contexts including medicine, photography, and media reporting, where distinguishing sharp from blurred details matters for interpretation.

In ophthalmology, blurry vision can result from various causes. Refractive errors such as myopia (miopía), hyperopia (hipermetropía), and astigmatism (astigmatismo) commonly lead to a borrosa vision. Other factors include dry eye, cataracts, and corneal edema. Persistent blurred vision warrants medical evaluation to identify and treat underlying conditions.

In photography and imaging, borroso describes out-of-focus images or motion blur. Causes include incorrect focus, camera shake, or low light. Remedies involve proper focusing, camera stabilization, higher shutter speed, or post-processing techniques to reduce blur, though some blur may be intentional for artistic effect.

In digital image processing, desenfoque gaussiano (Gaussian blur) is a common blur filter achieved by convolving an image with a Gaussian kernel. Blur can be used creatively or diagnostically, but since contrast and edge definition are reduced, the opposite effect is called nitidez (sharpness).
