Whatever the cause, vision changes should never be
ignored. They can get worse and significantly impact
the quality of your life. Professional help is always
necessary. As you determine which professional to
see, the following descriptions may help:
- Opticians dispense glasses and do not diagnose eye
problems.
- Optometrists perform eye exams and may diagnose
eye problems. They prescribe glasses and contact
lenses. In some states they prescribe eye drops to
treat diseases.
- Ophthalmologists are physicians who diagnose and
treat diseases that affect the eyes. These doctors
may also provide routine vision care services, such
as prescribing glasses and contact lenses.
- Sometimes an eye problem is part of a general health
problem. In these situations, your primary care
provider should also be involved.

Presbyopia-- difficulty focusing on objects that are close. Common in the
elderly.
Cataracts-- cloudiness over the eye's lens, causing poor nighttime vision,
halos around lights, and sensitivity to glare. Daytime vision is eventually
affected. Common in the elderly.
Glaucoma-- increased pressure in the eye, causing poor night vision,
blind spots, and loss of vision to either side. A major cause of blindness.
Glaucoma can happen gradually or suddenly -- if sudden, it's a medical
emergency.
Diabetic retinopathy-- this complication of diabetes can lead to bleeding
into the retina. Another common cause of blindness.
Macular degeneration-- loss of central vision, blurred vision (especially
while reading), distorted vision (like seeing wavy lines), and colors
appearing faded. The most common cause of blindness in people over
age 60.
Eye infection, inflammation, or injury.
Floaters-- tiny particles drifting across the eye. Although often brief and
harmless, they may be a sign of retinal detachment.
Retinal detachment-- symptoms include floaters, flashes of light across
your visual field, or a sensation of a shade or curtain hanging on one side
of your visual field.
Optic neuritis-- inflammation of the optic nerve from infection or multiple
sclerosis. You may have pain when you move your eye or touch it
through the eyelid.
Temporal arthritis-- inflammation of an artery in the brain that supplies
blood to the optic nerve.
Migraine headaches-- spots of light, halos, or zigzag patterns are
common symptoms prior to the start of the headache. An ophthalmic
migraine is when you have only visual symptoms without a headache.
Other potential causes of vision problems include fatigue, overexposure
to the outdoors (temporary and reversible blurring of vision), and many
medications.
