Your field of vision is the extent of space in which the eye can still capture objects while looking in one direction. Visual field tests do not quantify the quality of your vision. Instead, they put numbers to the range of vision. What Is Visual Field Testing? Visual field testing is an eye exam that […]

Your eyes have about 90 to 160 eyelashes on each lower lid and 75 to 80 on each upper eyelid, and overall you lose about one to five lashes a day. Eyelashes grow fast, reaching their full length in five to 11 months. Eyelashes will lengthen by 0.12 to 0.15 mm per day at each […]

Optic nerve cupping is also known as optic disc cupping. The “cupping” that doctors see stems from the death of smaller nerves around the optic nerve, creating a cup visual. The loss of the nerves concerns doctors because it could lead to loss of the primary nerve, which can lead to partial or total blindness. […]

The process is made possile through a series of eye changes by its lenses. Our eyes lose their accommodation ability as we get older, […]

When the brain receives signals from the eyes about an object or view that does not exist or that is distorted, it is called an optical illusion. The phenomenon points to an imperfection or malfunction in the vision system. Scientists have no hard explanation for these occurrences but suggest that evolution and physiology play a […]
