We will be happy to exchange the sight if it is defective, but what you are describing is a common first impression. Aimpoint and EOTech even address this in the FAQ's on their website - links to their FAQs are below.
Mount the sight on your rifle and take it shooting. Turn the brightness up only bright enough to see the reticle (this will vary based on the light level of your environment). Look straight through the sight with both eyes open and focus on the target, not the reticle. Have fun. Call us if you have any further questions.
