Seeing Shadows

Shadows in your vision can be a difficult thing to describe to your ophthalmologist. Different types of shadows can be associated with very different vision issues. For example, serious but common conditions, such as age-related macular degeneration, which can lead to partial or complete loss of central vision, may include a gradual full-vision darkening, sort of like the effect of peering through a sheer dark veil.

Retinal detachment, which most often results from vitreous fluid pulling away from and tearing the retina – and more rarely from injury, can bring about similar visual shadowing, but also may cause dark spots…

Avoid Computer Syndrome Eyestrain

In today’s work environment where everyone is required to stare at a computer monitor for long periods of time, eyestrain is almost inevitable. In fact, a new term has been coined for this type of discomfort, the “computer syndrome eyestrain”. There are cases when an underlying problem, such as uncorrected vision or muscle imbalance, can worsen the condition.

Causes and Symptoms

Aside from using the computer monitor, there are other causes of eyestrain. These include straining to see in dim lightening, exposure to bright lights, driving for long periods, and reading. Eyestrain can be very annoying, but it usually goes away…

Contact Lenses

A contact lens is a corrective or cosmetic lens placed on the cornea of the eye atop the iris. The idea of applying a corrective lens directly to the surface of the eye was first proposed and sketched by René Descartes in 1636, but in was not until 1887 that the German physiologist Adolf Eugen Fick constructed the first successful contact lens.

Made of various kinds of plastic, contact lenses come in a number of varieties, including hard and soft (although soft is by far more common now), and disposable and extended-wear. The specific dioptre needed to treat the patient’s condition…

Lasik

Lasik is a laser eye surgery that is used to correct vision problems such as near- or farsightedness. In lasik surgery, a laser is used to reshape the cornea of the patient. The lasik surgery can be performed as an outpatient procedure by a doctor in scrubs, though patients are advised to avoid rigorous physical activity while the eye heals. Lasik surgery can corrent many minor vision problems, though if those problems are severe enough, a patient may still require corrective lenses after the surgery
