In contact lens fitting, what does a loose contact lens pattern indicate?

• A. Good alignment and stability
• B. Poor lens centering
• C. Inadequate tear film distribution
• D. Normal variations in fitting

Answer: (B)

A loose contact lens pattern indicates poor lens centering. When a contact lens fits too loosely, it does not sit properly on the cornea, which can result in excessive movement during blinking and daily activities. This improper alignment can lead to discomfort and blurred vision because the lens may not maintain consistent contact with the eye's surface. Proper fitting requires that the lens aligns well with the corneal shape, providing stability and ensuring that the lens remains centered over the pupil. A loose fit can also cause issues with the distribution of tear film beneath the lens, leading to dryness or irritation, but the primary indicator in this context is that the lens is not centered properly on the eye. Adequate positioning is crucial for optimal vision and comfort while wearing contact lenses.
