Age-related vision changes happen to many people as they grow older. But eye problems aren't something you should simply write off as normal.
Some problems stem from new or worsening vision disorders. As you get older, these might happen gradually. Others happen suddenly, quickly causing blindness. That is why regular exams with an eye doctor are so important.
Eye twitching is a repetitive, uncontrollable blinking or spasm of the eyelid, usually the upper lid.
Eye twitching (blepharospasm) usually affects the eye muscles of both eyes. If you have eye twitching, you may have an involuntary movement that recurs every several seconds for a minute or two.
Most people develop a minor eyelid twitch at some point in their lives. Although the cause is generally unknown, it may be associated with:

You can take steps to lower your risk of age-related vision problems. Or, if you have changes, you can slow their progression.
Age-Related Macular Degeneration (AMD)
With AMD, the macula, or central part of the tissue that lines the back of the eye (the retina), becomes damaged. This makes tasks involving central vision -- reading fine print, for example -- much harder. But you do maintain side vision.
The dry type of AMD affects 9 out of 10 people with macular degeneration. It causes more gradual, subtle vision loss from the breakdown of cells in the retina. For example, you may see parts of letters, or straight lines may appear wavy. The dry type of AMD can develop into the wet type.
Other symptoms include:
Needing extra light or having trouble when going from bright to low light
Trouble reading or recognizing people's faces
Colors appearing less vivid
The wet type of AMD causes sudden, severe loss of central vision from leaking blood vessels growing in or under the retina. You may see a large dark spot in the center of your vision. If you have these blind spots, see an eye doctor right away.
Other symptoms include:
Objects appearing a different size for each eye
Colors appearing less vivid or differently in each eye
You may be more likely to get AMD if you smoke, have a family history of AMD, or are obese.
Other risk factors include genetics, exposure to ultraviolet (UV) light, and a lack of nutrients reaching the retina.
There is no cure for AMD, but there are options that may slow the progression of wet macular degeneration.
Anti-VEGF treatment limits growth of new blood vessels in the eye that can threaten vision.
Thermal laser treatment uses heat to disrupt the disease.
Photodynamic therapy destroys blood vessels in the eye that are leaking and damaging vision.
Your doctor may recommend you take certain vitamins and minerals -- including zinc, vitamins C and E, and lutein and zeaxanthin -- in specific doses to slow down AMD when it’s still in its early stages.
