@dr.ilancohen: If one finger makes a light split, smear, or starburst, that is not something to ignore. This quick at home check can reveal an early sign of keratoconus, a condition where the cornea thins and starts to bulge, causing distorted, unstable vision. A lot of people think their glasses prescription just keeps changing, when the real issue is something much more serious. The good news? If caught early, keratoconus can often be stopped with corneal cross linking before vision gets much worse. So if the light looks weird when you do this test, do not spend 3 weeks Googling it.
Book the appointment. Your corneas do not get a second chance. Send this to someone whose glasses prescription never seems to stabilize. #Keratoconus #EyeDoctor #EyeHealth #Cornea #VisionProblems
