When self-preparing your taxes and filing electronically, you must sign and validate your electronic tax return by entering your prior-year Adjusted Gross Income (AGI) or your prior- year Self-Select PIN. Using an electronic filing PIN is no longer an option.
The pupil of one eye is larger than the other and this condition is observed in a disorder named as Anisocoria. The quantity of light that enters the eye is controlled by the pupil. The pupil narrows down in bright light and dilates in low light. The muscles in the Iris region show some problem in getting dilated and hence lead to Anisocoria.
Things that can make pupils smaller include a well lighted room and medications such as narcotic pain killers. Keep in mind that the pupillary size is adjusted by the brain to allow a certain amount of light into the eye for the retina to see. If your pupils are small, but you can see fine, your brain is essentially saying that your pupils do not need to be any bigger to allow an adequate amount of light into the eye.
