| Macular Degeneration: The Sneak Thief of Vision |
Age-Related Macular Degeneration (AMD) is considered to be the leading cause of functional vision loss in people over the age of 55 in the western world. Estimates of how many people are affected vary considerably, but the percentage of the population with it increases with age. While only 2% of people aged 50 to 59 have the disease, the incidence rises to nearly 30% by the age of 75 years. Therefore, the greatest risk factor for developing this condition is age.
There is important new inf...

| Mature Vision: Presbyopia |
By early adulthood, the human eye is fully developed; at its maximum potential it includes various components that are not easily measured by traditional eye charts, such as depth perception, night vision and hand-eye coordination. However, vision does still change over time.
By about the age of 40, the symptoms of "presbyopia" begin to become noticeable, most commonly by difficulties reading fine print or using a computer for extended time periods. Presbyopia is one of the four "refract...

| Meibomitis |
Other causes of meibomitis include acne rosacea and blepharitis.
Overview
Along the margin of the lids there are a series of small sebaceous glands called the meibomian glands. They create and distribute an oily substance called lipids. Meibomian gland secretions help keep the eye moist and protect the tear film from evaporation. Upon blinking the upper lid comes down presses on the oil and pulls a sheet of oil upwards coating the tear layer beneath to keep it from evaporating. Meibomit...

| Myokymia (Eyelid Twitching) |
As eyecare practitioners, we frequently hear from patients that they are bothered by twitching in the eyelid of one eye. The eyelid muscles around one eye (only rarely in both) will begin to quiver involuntarily; episodes can be as frequent as several times a day or perhaps once a week.
To the person experiencing it, the entire lid feels like it might be moving, but in reality it is a very small movement, almost unnoticeable by others. While it can be annoying, the twitching is not ser...

| Myopia |
Technically known as myopia (my-O-pe-ah) nearsightedness is a vision problem that affects over 25 per cent of adults worldwide and it is the most common vision problem in the United States. Nearsighted people experience difficulty seeing objects at a distance but can see objects at close range. Myopia occurs because the eyeball is too long as measured from front to back. Thus light focuses in front of the retina instead of directly on it causing blurred distant objects.
Nearsightedness can...

| Myopia: What Causes It? |
Myopia is a refractive error also known as nearsightedness or shortsightedness. (Refractive errors are named for where the uncorrected vision is better; in this case, nearsightedness gives good vision up close, but blurriness for things in the distance.)
In an eye that is myopic, light rays entering the eye are brought to a focus in front of the retina instead of exactly on it, so images are blurry instead of being sharp and clear. When the myopic person gazes at something ...
