Explanation: Unlike the natural "blind spot" that we all have in our peripheral vision, a blank spot right in the center of your vision is not normal. This type of blind spot is caused by age-related macular degeneration (AMD) -- one of the most common causes of vision loss in older adults.
Symptoms include blurriness, dark spots in the central area of vision, difficulty seeing faces clearly, and trouble seeing when going from bright light to low light.
AMD doesn't usually cause total blindness, but it can make it impossible to perform daily tasks like driving and reading. Early intervention can help to slow its progression. Taking Vitamin E, C, beta carotene, and zinc supplements has been shown to slow the progression of age-related macular degeneration for some people. The "wet" form of this condition can also be treated.
If you have a tender, red bump on the edge of your eyelid, you may have a stye, or clogged gland called a chalazia. Treat it with a clean, warm compress three to five times a day, and it should drain on its own. Don't squeeze or try to "pop" it. See a doctor if it doesn't get better with home treatment.
An eyelid twitch can be annoying but is usually not serious and will go away on its own. See your doctor if the twitching lasts longer than a week.
