- The type of vision problem that you have determines the shape of the eyeglass lens. For example, a lens that is concave, or curves inward, is used to correct nearsightedness, while a lens that is convex, or curves outward, is used to correct farsightedness. To correct astigmatism, which is caused by distortions in the shape of the cornea, a cylinder shaped lens is frequently used.

What Is a Stroke? In the long term, in some cases, visual field defects from stroke may improve, although there are often permanent deficits. After a stroke, the patient should undergo formal visual field testing by an eye doctor or neurologist to identify precisely the part of the visual field that has been affected.

1. Which one of the following is a green house gas? Carbon dioxide 2. The tallest living tree is Sequoia 3. These eyeglass lenses are unlike typical lenses, which are spherical in shape. Aspheric lenses are made up of differing degrees of curvature over its surface, which allows the lens to be thinner and flatter than other lenses. This also creates an eyeglass lens with a much larger usable portion than the standard lens.

What Is a Visual Field Test? What Is a Visual Field Test? The visual field is the entire area (field of vision) that can be seen when the eyes are focused on a single point. In addition to what can be seen straight ahead, the visual field includes what can be seen above, below, and to either side of the point the eyes are focused on. Vision is typically the sharpest in the middle of the visual field. A visual field test is often given as part of an eye exam.

All about Acetate What is the difference between cellulose acetate frames and injection molded plastic frames? Cellulose acetate is hypoallergenic, made from a renewable resource, lightweight, and very strong. It is made from cutting, forming and polishing sheets of plastic. Cellulose acetate is the highest quality plastic material for eyeglasses. As the name implies, injection mold frames are made by injecting a more brittle petroleum based plastic that is liquified, then injected into an aluminum or stainless steel mold.

- A prism is a clear, triangular device made up of plastic or glass (or any transparent material). When white light goes through a prism, the light bends due to the phenomenon called refraction. Refraction is the process of bending light as light goes from one medium (like air) to another medium (like water or glass). The bending happens because light changes speed as it goes from one medium to another.

Why Do I Need a Visual Field Test? The visual field test is a subjective measure of central and peripheral vision, or “side vision,” and is used by your doctor to diagnose, determine the severity of, and monitor your glaucoma.maging of the optic nerve and surrounding tissues is an objective test that can also detect glaucoma damage and progression. This information can help your doctor make treatment decisions, and as the technology improves it will be even more useful. However, at this time it has not replaced the visual field test.

What is orthoptics? What is orthoptics? The word orthoptics comes from the Greek ortho (straight) and optikos (vision). Orthoptics is a specialized field in ophthalmology that deals with binocular vision (the use of both eyes together) and very specific eye problems such as: Amblyopia (reduced visual development in one or both eyes) Strabismus (crossing or misalignment of the eyes) Diplopia (double vision)

Visual Field Testing Visual field testing is a sophisticated, automated computerized vision test that measures both central and peripheral vision/visual function. It is essential in monitoring glaucoma and it is a useful ancillary test to diagnose, document or treat neurologic or retinal disease.

DIAGNOSING GLAUCOMA Visual Field Test. Visual field is an important measure of the extent of damage to your optic nerve from elevated IOP. In glaucoma, it is the peripheral (side) vision that is most commonly affected first. Testing your visual field lets your doctor know if peripheral vision is being lost.

Eyeglasses Through the Ages Round lenses were almost universal until the end of the 18th century when oval lenses became fashionable. Frames went through a similar evaluation and evolution. The earliest frames were made of wood, horn, or bone. Leather frames had a relatively short life span from the 16th to the middle of the 18th century. Few have survived to present day time and those are highly sought after. The first frames were for round lenses, followed by oval, and eventually rectangular ones became popular in the mid-1830’s.

Visual Field Testing: From One Medical Student to Another Acuity is tested with vision charts of letters or images. Changes in luminous intensity are perceived as flicker, and the difference in luminous intensity from one object to another is perceived as contrast [1]. The visual field encompasses the entire region of space seen while gaze is directed at any central object. This tutorial explains visual field testing.
