Why Diabetes Demands a Different Approach to Contact Lens Care

Diabetes fundamentally alters how thee eye responds to so stress, infection, and even the simple act of aing contact lenses.

Te tear film in diabetic patients tends to be unstable.

Beyond thee immediate risks, diabetes can also cause corneal endothelial cell loss over time, reducing the cornea 's ability to pump fluid out and maintain clarity.

Step-by- Step Selection Guide for Diabetic Contact Lens Wearers

Step 1: Schedule a Comtremsive Diabetic Eye Exam

Before choosing any solution, youu need a curret assessment of your corneal health, tear film status, and any signs of diabetic retinopatiy or ther complications. Your eye care professional can evaluate corneol sensitivity, measure tear production with a Schirmer test, and check for epitelial defects with fluorescencein distang.
