Sam's Club Optical reveals four main reasons that contact lenses become blurry, including protein deposit build-up, dry eye syndrome, deteriorated or scratched contact lenses and blurriness that isn't related to the contact lens. Most problems with blurry contact lenses are solved by maintaining a regular contact cleaning schedule and wearing the proper type of contact lens.

Protein build-up is the most common cause of contact lens blurriness. Sam's Club Optical reveals that tears contain protein and oils that attach to small grooves on the contact lens. Over time, a film develops on the surface of the contact, leading to distorted, blurry and cloudy vision.

According to Sam's Club Optical, dry eye syndrome is a condition in which the eyes become inflamed and dry. This sometimes leads to blurry vision and an increased risk of eye infection and damage.

Sam's Club Optical explains that deterioration of a contact lens can occur by wearing a contact lens for too long, scratching the lens or using corrosive chemicals to clean the lens. Sometimes, the contact lens isn't the cause of blurry vision. Because it may be a sign of a more serious eye condition, blurry vision that is persistent or worsening requires evaluation by an eye care professional.
