Pink eye  also called conjunctivitis  is inflammation of the thin, clear covering of the white of the eye and the inside of the eyelids (conjunctiva). Although the conjunctiva is transparent, it contains blood vessels that overlay the sclera of the eye.
Health Reimbursement Account is a notional derivative of a Health Reimbursement Arrangement (HRA), a type of US employer-funded health benefit plan that reimburses employees for out-of-pocket medical expenses.
One of the most important differences between the two is that the employer owns the HRA and the employee owns the HSA. This means that the employee takes the HSA along when he or she changes jobs. If an employee with an HRA changes or loses his or her job, any remaining amount in an HRA defaults to the employer.
