Flashes and Floaters
Floaters and flashes are a common sight for many people. Floater is a catchall term for the specks, threads, or cobweb-like images that occasionally drift across the line of vision. Flashes are sparks or strands of light that flicker across the visual field. Both are usually harmless. But they can be a warning sign of trouble in the eye, especially when they suddenly appear or become more plentiful.
Dry Eyes
Dry eyes is a common condition that occurs when your tears aren't able to provide adequate lubrication for your eyes. Tears can be inadequate for many reasons. For example, dry eyes may occur if you don't produce enough tears or if you produce poor-quality tears.
Retinal Detachment
Retinal detachment describes an emergency situation in which a thin layer of tissue (the retina) at the back of the eye pulls away from its normal position.
Retinal detachment separates the retinal cells from the layer of blood vessels that provides oxygen and nourishment. The longer retinal detachment goes untreated, the greater your risk of permanent vision loss in the affected eye.
Warning signs of retinal detachment may include one or all of the following: the sudden appearance of floaters and flashes and reduced vision. Contacting an eye specialist (ophthalmologist) right away can help save your vision.
Double Vision
Double vision can occur with one eye or both. If it's in one eye when the other is closed, it is less worrisome, but still serious. If it occurs when both eyes are open, it could signal a major disorder.
Myopia, Hyperopia, Presbyopia, Astigmatism
Myopia (Nearsightedness)
Nearsighted individuals typically have problems seeing well at a distance and are forced to wear glasses or contact lenses. The nearsighted eye is usually longer than a normal eye, and its cornea may also be steeper. Therefore, when light passes through the cornea and lens, it is focused in front of the retina. This will make distant images appear blurred.
Hyperopia (Farsightedness)
Farsighted individuals typically develop problems reading up close before the age of 40. The farsighted eye is usually slightly shorter than a normal eye and may have a flatter cornea. Thus, the light of distant objects focuses behind the retina unless the natural lens can compensate fully. Near objects require even greater focusing power to be seen clearly and therefore, blur more easily.
Presbyopia
Presbyopia is a condition that typically becomes noticeable for most people around age 45. In children and young adults, the lens inside the eye can easily focus on distant and near objects. With age, the lens loses its ability to focus adequately.
Astigmatism
Asymmetric steepening of the cornea or natural lens causes light to be focused unevenly, which is the main optical problem in astigmatism. To individuals with uncorrected astigmatism, images may look blurry or shadowed. Astigmatism can accompany any form of refractive error and is very common.
Glaucoma
Glaucoma is a group of eye conditions that damage the optic nerve, the health of which is vital for good vision. This damage is often caused by an abnormally high pressure in your eye.
Glaucoma is one of the leading causes of blindness for people over the age of 60. It can occur at any age but is more common in older adults.
Cataracts
A cataract is a clouding of the normally clear lens of your eye. For people who have cataracts, seeing through cloudy lenses is a bit like looking through a frosty or fogged-up window. Clouded vision caused by cataracts can make it more difficult to read, drive a car (especially at night) or see the expression on a friend's face.
Styes and Chalazions
A stye is inflammation that causes a tender red lump on the eyelid. Most styes occur along the edge of the eyelid. When a stye occurs inside the eyelid, it is called an internal hordeolum.
Chalazions are lumps in the eyelid. Chalazia (plural) may look like styes, but they are usually larger and may not hurt.
Pterygium
A Pterygium is a wing-like growth on the surface of the eye, usually in the inner corner, and can spread over the cornea or clear part of the eye.
Macular Degeneration
Macular Degeneration is caused by the deterioration of the central portion of the retina, the inside back layer of the eye that records the images we see and sends them via the optic nerve from the eye to the brain. The retina’s central portion, known as the macula, is responsible for focusing central vision in the eye, and it controls our ability to read, drive a car, recognize faces or colors, and see objects in fine detail.
Lid Lesions and Growths
An eyelid lesion may be pigmented or colored. These include relatively common disorders such as styes and chalazia, which are small bumps on our eyelids.
Allergic Reactions
In this case, allergic reactions include eyes that water, itch, hurt or become red or swollen. The most common causes of allergic conjunctivitis are seasonal allergenssuch as pollen and mold spores.
Iritis
Iritis is inflammation that affects the colored ring around your eye's pupil (iris). The iris is a part of the middle layer of the eye (uvea), so iritis is a type of uveitis, also known as anterior uveitis.
Botox
Botox around eyes are specifically used to soften the appearance of crow's feet and the "11" lines, and to correct the asymmetric eyelids or eyebrows.
