You are allowed up to $1400.00 for loupes. If you purchase from Designs for Vision and pay $850.00 you will only be reimbursed $850.00. If you purchase from Ziess for $3000.00 you will only get back $1400.00. The Army does not pay for lights, engraving the box or any other doo dads.
This is all based on the supposition that loupes are required of all students in your year group as verified by the school's billing office. In other words, the Army will not reimburse for loupes that are required in year three while you are in year one. Also, there is a huge difference between required and recommended.
