Why am I seeing funny shapes and spots?

What is a “lazy eye?”
The medical term for “lazy eye” is AMBLYOPIA: a healthy eye that does not see. The eye became amblyopic either because the eyes were crooked or one eye had a very different refractive error than the other. To eliminate double vision the brain preferred to use one eye only. More…

Why is my eyesight at night time not a clear as it is during the day time?
There are several causes for blurry vision during dim/low light conditions. The refractive power of the eye changes in the dark. That is because the pupil dilates and changes the
eye’s aperture. In dim light nearsighted people become MORE nearsighted. They call this NIGHT MYOPIA. Some folks who do not need daytime glasses still need a nighttime prescription.

The healthy eyeball remains moist due to the presence of a three-layer tear film. The outmost layer is oil, the middle layer is water, and the tear layer closest to the cornea is mucus. Tiny, microscopic glands deep in the eyelids called the ACCESSORY LACRIMAL GLANDS produce the water layer. Do not confuse these with the big lacrimal gland above the eyeball. More…
