Yes, by relaxing and strengthening the eye
muscles
Prescription glasses, Vision therapy with
biofeedback

Injury
No.
Sometimes will heal itself
Antibiotics to prevent infection, other
medication
Corneal
Neovascularization
New
blood vessels grow into the cornea causing it to become cloudy and block
light going through
Insufficient oxygen flow to the cornea. e.g.: excessive use of contact
lenses
Great
for prevention
Remove your contacts. Need medical
professional attention, may lead to blindness
Diabetic
Retinopathy
Blurred vision, dilation of and small hemorrhages in the blood vessels of
the retina which may spill into the vitreous of the eye causing retinal
detachment and blindness
Complication of diabetes mellitus which affects blood vessel going to the
eyes
Great
help
Laser surgery may help temporarily stop the
hemorrhages
Double
Vision
Image
seen becomes double
Breakdown of eye coordination or other eye disorders
Yes
Prescription glasses with prism, brain
training, surgery
Dry-Eye
Syndrome
Dryness, redness, burning, grittiness, excessive tearing, sensitive to
light
Allergy, arthritis, other autoimmune disorder
Yes, give your eyes the necessary nutrients
Eye drops, plugging the hole in the tear
"sink"
Eyestrain
Discomfort, easily tired
Various causes
Yes, you need eye muscle exercises and
nutrients
Eyeglasses, vision therapy
Farsightedness
(Hyperopia)
Image of an object 20 or more
feet away is focused behind of the retina and looks blurred
Refractive error of the eyes, lens is relaxed, cornea too flat, or a
combination
Yes
Prescription glasses, vision therapy
Floaters
Dark
spots in front of the eyes especially when looking at bright areas
Strands of old bloods floating in the vitreous of the eye, protein fibers
from the gel in the vitreous clump together
Yes
None
Giant
Papillary Conjunctivitis (GPC)
A
type of pinkeye. itchy, white mucous discharge, contacts feel dry
Wearing contact lenses, irritated by foreign bodies
Great
help
Discontinue using of contact lenses, can
develop into a chronic condition if not treated properly
Glaucoma
Pressure inside the eye is markedly elevated and prevent blood from
reaching, nourishing, and circulating through the eyes
Drainage problem, the eye cannot get rid of the excessive aqueous humor
fast enough
Great
help
Medication, surgery. Glaucoma is a
serious eye disorder that may lead to blindness. Beware of side
effect of medication
Hypertensive
Retinopathy
Fluid
gradually seep out of the weakened blood vessels into the space within the
structure of the retina. This eventually clots and forms scar tissue,
which pulls on the structure of the retina, causing blindness in extreme
cases.
High
blood pressure
Great
help
High blood pressure medication, laser
treatment to seal off leakage in blood vessels
Iritis
Inflammation of the iris
Unknown, may be related to other diseases and infection in another part of

distortion of vision
Unknown
Helpful

area of the retina are thinner than normal leading to possible development
of retinal holes, tears or detachment
Unknown
Helpful

Light
Sensitivity
(Photophobia)
Overly sensitive to light
Excessive wearing of contact lenses, poorly fitting of contact lenses, eye
diseases, injuries, infections, an many other reasons
(Wet
Form) Abnormal blood vessels leak causing damage to the macula resulting
in rapid and severe vision loss.
(Dry form)
Small yellowish deposits called drusen start to accumulate beneath the
macula gradually breaking down the light-sensing cells in the macula
causing distorted vision.
