Currently my veins going into cornea. could blepharitis/giant papillary conjunctivitis be the cause of it?

Yes: Giant papillary conjunctivitis is generally a chronic response to contact lens wear, contact solutions and sometimes environmental allergens. When it becomes chronic, vessels can grow into the superior cornea and these can threaten vision. Discuss this with an ophthalmologist as treatment is needed.

See your doctor: This is a problem that requires a face-to-face meeting with your doctor. In that meeting, your doctor will listen to you, perform a throrough examination and possibly order labs or other tests. Based on this information, he/she will be able to tell you what's wrong and what to do about it.
