Astigmatism
Cornea is shaped like a football vs a softball. Have trouble seeing close and far away
Cylinder
Ex: -1.00, 0.75 indicates the amount of lens power for astigmatisms. If nothing appears, then you have no astigmatism

Macular degeneration
Deterioration of the central retina; causes black or blurry spot in the middle of vision. When the cells of the macula deteriorate, images are not received correctly.
Dry macular degeneration
85-95% of all cases. Atrophic type- Waste away, due to degeneration of cells
Wet Macular degeneration
10-15% Exudative type. Fluid Emitting through pours or a wound.
Axis
-Where the vision is blurred from 1 degree- 180 degrees. -Lens meridian that contains no cylinder power to correct astigmatism. -90 corresponds to vertical meridian of the eye -180 corresponds to horizontal meridian -If there is cylinder power, it myst include axis

PO
medication taken by mouth
Diabetic retinopathy
High Blood sugar levels cause damage to blood vessels in the retina. These blood vessels can swell and leak, or they can close, stopping blood from passing though
Glaucoma
Disease that damages your eye’s optic nerve. Happens when fluids build up in the front part of your eye. That extra fluid increases the pressure in your eye, damaging optic nerve.
Retina
sensitive to light and trigger nerve impulses that pass via the optic nerve to the brain. The retina absorbs light and transmits vision (like film in a camera)
Cataracts
(posterior) clouding of the normally clear lens of the eye. Symptoms: Blurry vision, looking though a frosty or fogged up window.
Autorefraction
Approximation of a patients prescription. It also tells us the shape of the cornea, so that we can know what kind of contact lens shape to choose for a patients

Convergence
Where both eyes point to the same object at the same time when looking up close at an object
Cornea
Transparent front surface of the eye that covers the iris, pupil, and anterior chamber. -Contributes to the image- forming process by refracting light entering the eye
Arcus is
Ring around the periphery of cornea caused by high cholesterol- lipid buildup that concentrates in limbus area of cornea
SPK (superficial punctate) Kertitis is
Surface irriation. Irritation of the cornea caused by a number of things. Most common complaint: dry eye; CL overwear
Iris is the
Pigmented muscle that lies between the cornea and the lens of eye; it acts as a disphragm to widen or narrow the opening called the pupil, therby controlling the amount of light that enters the eye
Pupil is the
The opening within the iris through which light passes before reaching the lens and brings light into the retina
Bulbar Conjunctiva is
Clear membrane covering the outer portion (Sclera) of the eyeball. It protects the eye.- contains blood vessels seen on the white part of eye.
Sclera
White part of eye
Hyperemia
Red eyes (usually inflammed)
Subconjuntional Hemorrhage
Ruptured blood vessel that causes blood to be trapped between sclera and bulbar conjunction
Palpebral Conjuntiva
Part of the conjunctiva that forms the underside of the lids
Papillae is
Polygonal “Cobblestone” conjuntivial projections with a central network of fine branching vessels (located on the palpebral conjunctive)- Present in patients with allergic conjunctive
Crystalline lens
Positioned behind the iris and is transparent and elastic- it refracts light entering the pupil and focuses of the retina.
Posterior capsular opacification
Clouding of the normally clear posterior lens capsule after cataract surgery *Patients need YAG capsulotomy to bust open the capsule to remove haze over vision.
Amblyopia
When the visual pathway has been damaged and one eye does not see well due to high Rx or (lazy eye) eye turn
Adnexa
The adnexa of the eye are a group of appendages in the eye area that primarily protects the organ.
Canalicular stenosis
Canalicular stenosis and obstruction related to punctual plugs is associated with accumulation of debris, including inflammatory reactions resulting in scar formation along with injury to canaliculus by the act of probing itself, prior to plug insertion.
Canaliculi
The canaliculi are segments of the tear duct system that connect the puncta to the lacrimal sac and remaining nasalacrimal duct.

Patching
Patching is a technique for treating amblyopia (lazy eye). The good eye is covered to encourage the development of the lazy eye. Amblyopia can be caused by unequal refractive errors, crossed eyes, misaligned eyes (strabismus), or other abnormalities
Strabismus
Poor eye muscle control
Amblyopia
“lazy Eye” Amblyopia is the medical term used when the vision in one of the eyes is reduced because the eye and the brain are not working together properly.

Pupils test
Using light to check pupil response to light. get mm for DIM and BRIGHT.
Confronation/Automated
putting numbers to the side. making patient look without moving eyes.

8 inches = about how many cm?
about 20 cm
Adnexa
The adnexa of the eye are a group of appendages in the eye area that primarily protects the organ.
Canalicular Stenosis
(Adnexa) Punctal stenosis results in a narrowing in the opening of the tear duct system which is referred to as the puncta
Xanthelasma
(Adnexa) Xanthelasma is a sharply demarcated yellowish deposit of cholesterol underneath the skin, usually on or around the eyelids.
Blepharochalasis
(adnexa) Blepharochalasis is an inflammation of the eyelid that is characterized by exacerbations and remissions of eyelid edema, which results in a stretching and subsequent atrophy of the eyelid tissue, leading to the formation of redundant folds over the lid margins.
Dermatochalasis
(Adnexa) Dermatochalasis is a medical condition, defined as an excess of skin in the upper or lower eyelid, also known as “baggy eyes.”
Papilloma
(Adnexa) A papilloma is a benign epithelial tumor growing exophytically in nipple-like and often finger-like fronds
Skin Tag
(Adnexa)
Blepharitis Ulcerative
(adnexa) inflammation of glands and lash follicle on lid.
Ptosis
(adnexa) Ptosis is a drooping or falling of the upper eyelid.
Chemosis
(adnexa) Chemosis is the swelling of the conjunctiva. It is due to the oozing of exudate from abnormally permeable capillaries. In general, chemosis is a nonspecific sign of eye irritation. T
Ecchymosis
(adnexa) Raccoon eye sign or blepharohematoma refers to periorbital ecchymosis which is usually due to trauma on the frontal area of the skull, leading to rupture of the veins of anterior cranial fossa.

Myopic prescriptions
(minus or near sighterd) will be thicker at the EDGES than the center.
Hyperopic prescription
farsighted or plus Rx will be thicker in the CENTER. thin or rimless frams may not be suitable for these lenses because the edge is the thinnest portion and cannot always be securely fitted into frame.
what kind of frame would you use for a high Rx?
plastic so that the lens stay more secure into frame.
what kind of frame for bifocal?
a larger lens depth so that they have more room for readign and distance.
How should eye sit in frame?
eyes should sit at the horizontal center of the lens and vertically in the top third.
How should eyes NOT sit in frame?
too nasally or too temportal
why do glasses need to fit right?
1) so that they are not always sliding and falling off your face.
2) eyes need to be centered according to you prescription. lens is either thicker or slimmer in the middle.
to stay in place, your frame needs something to hold onto. too wide, and there will be no grip on your temple; the frame will sit heavy on your nose and leave a mark. If the frame is too wide and you have a lower nose bridge, the frame will constantly slop out of place. Too narrow and the temples will pinch the side of your face and leave painful red marks.
Anti glare coatings
coating is applied to back and front of lenses. AR coating makes your lenses nearly invisible so people can focus on your eyes, not distrcting reflections from your eyeglasses.
Clear vision and longer lens live.
fingerprint resistant, increases clarity, scratch resistance and glare resistant.
polycarbonate material
thinner and lighter, UV protection, 10x more impact resistant than plastic or glass lenses.
10% thinner than trivex.
great for childeren because they are flexible and durable.
Trivex material
10% lighter than poly. thinner and lighter, UV protection, 10x more impact resistance than platic or glass.
