Near or Farsightedness
When you’re nearsighted, distant objects appear blurry. When you’re farsighted, near and sometimes distant objects appear blurry.
When you have astigmatism, objects are blurry at all distances and it’s often accompanied by near or farsightedness.
Presbyopia makes it difficult to focus on near objects or smaller print, especially in low light, starting at around age 40.
Muscles having to work extra hard so as to compensate for other muscles that are not working hard enough. It is characterized by one muscle becoming bigger and stronger while the other becomes small and weak.
Part of vision that occurs outside the very center of gaze.
The gradual breakdown of the cornea, the clear dome on the front of the eye that covers the iris and pupil. The cornea is also responsible for refracting light, along with the lens of the eye, so corneal degeneration results in a gradual loss of vision.
is an eye condition characterized by chronic inflammation of the eyelid, the severity and time course can vary.
Blocked Tear Ducts
A blocked tear duct is when the eye’s drainage system for tears is either partially or completely obstructed. Tears cannot drain normally, causing a watery, irritated or chronically infected eye.
is a term describing a group of ocular disorders by a clinically characteristic intraocular pressure-associated optic neuropathy. This can permanently damage vision in the affected eye(s) and lead to blindness if left untreated. It is normally associated with increased fluid pressure in the eye
Is a condition in which there are insufficient tears to lubricate and nourish the eye. Tears are necessary for maintaining the health of the front surface of the eye and for providing clear vision.
A stye is an infection that causes a tender red lump on the eyelid. Most styes occur along the edge of the eyelid.
Conditions which affect the structure or function of the pupil of the eye, including disorders of innervation to the pupillary constrictor or dilator muscles, and disorders of pupillary reflexes.
Is a medical condition which usually affects older adults and results in a loss of vision in the center of the visual field because of damage to the retina. It occurs in “dry” and “wet” forms.
called allergic conjunctivitis, are a common condition that occurs when the eyes react to something that irritates them (called an allergen). The eyes produce a substance called histamine to fight off the allergen. As a result, the eyelids and conjunctiva — the thin, filmy membrane that covers the inside of your eyelids and the white part of your eye (sclera) — become red, swollen and itchy, with tearing and burning. Unlike bacterial or viral conjunctivitis, allergic conjunctivitis is not spread from person to person.
Pink Eye or Conjunctivitis
Is inflammation of the conjunctiva (the outermost layer of the eye and the inner surface of the eyelids). It is most commonly due to an infection (usually viral, but sometimes bacterial) or an allergic reaction.
Is a clouding of the lens inside the eye which leads to a decrease in vision. It is the most common cause of blindness and is conventionally treated with surgery. Visual loss occurs because opacification of the lens obstructs light from passing and being focused on to the retina at the back of the eye.
Lazy Eye or Amblyopia
Is an eye disorder characterized by an impaired vision in an eye that otherwise appears normal, or out of proportion to associated structural abnormalities of the eye. It has been estimated to affect 1-5% of the population.
Is an inflammatory of the cornea involving disruption of its epithelial layer with involvement of the corneal stroma. It is a common condition in humans, children afflicted by Vitamin A deficiency are at high risk for corneal ulcer and may become blind in both eyes.
