Slim, Nice Figure, Ideal Weight and Attractive. What’s Being Described Here?

Hi-index lenses offer people who wear eyeglasses with lens choices that are thin, light and attractive.

For people who have strong prescriptions for nearsightedness, farsightedness or astigmatism, hi-index lenses are a great way to avoid lenses that are thick, heavy and distort the natural appearance of your eyes.

The lenses in a pair of eyeglasses correct vision by bending or refracting light as it passes through each lens.  With conventional plastic and glass lenses, the more light that needs bent, the alternatives to thick eyeglassesthicker the lenses must be.

Hi-index lenses are different.  Here’s how they work and the benefits they offer:

Increased Light Bending Abilities

Hi-index lenses are made of a special material that is able to bend or refract light much more efficiently than conventional lenses.  This means less lens material needs to be used to bend the appropriate amount of light that corrects vision.

Thin Construction

Due to the increased ability to bend light, hi-index lenses are much thinner than conventional plastic and glass lenses. Therefore, the profiles of eyeglasses are not dominated by thick lenses when hi-index lenses are used.

Comfortable Wear

Because less material is used with hi-index lenses, they do not weigh as much as conventional lenses. This makes them light weight and comfortable to wear.

The fashions of today’s most popular frames have either very thin rims or no rims at all (rimless frames). The thickness of the lens becomes very important with these styles of eyeglass frames.  When lenses are too thick, the balance between the frames and lenses becomes disproportionate, resulting in a pair of eyeglasses that are not as cosmetically appealing as they could be with hi-index lenses.

Ask Your Eye Doctor About Hi-Index Lenses

Discuss hi-index lenses with your eye doctor to see if they are an option for you and your vision correction needs.  They may provide you with the function, comfort and appearance you desire in a pair of eyeglasses.

Three Main Types of Retinal Detachment

Eye anatomy and eye careThe retina is a thin, light-sensitive membrane covering the rear of the eye. It’s the part of the eye where images are focused by the cornea and lens. The images displayed on the retina are transmitted to the visual centers of the brain by the optic nerve. In fact, the retina is technically part of the body’s central nervous system and is considered brain tissue.

Approximately 95% of the retina is responsible for side vision or peripheral vision. The remaining 5% located in the very center of the retina is known as the macula and allows for central vision.

If the retina becomes damaged or separates from the back wall of the eye, it’s a condition known as retinal detachment.  When a retinal detachment occurs, it’s a serious condition that needs attention. A retinal detachment causes the retina to separate from its blood and nutritional supply which could lead to loss of peripheral vision, central vision or both.

There are three (3) main types of retinal detachment:

retinal detachmentRhegmatogenous Retinal Detachment (RRD)

This is the most common type of retinal detachment. The term rhegmatogenous means “arising from a rupture or a fracture”.  Rhegmatogeous retinal detachment occurs when there is a hole or a tear in the retina. The break in the retina allows the gel-like substance from the vitreous cavity of the eye to seep through the opening causing the retina to detach from the eye wall.

Tractional Retinal Detachment (TRD)

A tractional retinal detachment is a retinal detachment caused by the gel like substance within the vitreous cavity of the eye pulling on the retina which eventually causes the retina to detach from the rear eye wall.

Exudative Retinal Detachment (ERD)

An exudative retinal detachment occurs as a result of a leak under the retina which allows the gel-like vitreous substance to enter behind the retina. These types of leaks are typically caused by inflammation.

Symptoms of Retinal Detachment

Flashing lights and eye floaters are common early symptoms associated with a retinal tear or retinal detachment.  If a dark shadow or dark curtain obscures a portion of vision, this is also an indicator of retinal detachment.  Anyone who experiences these symptoms should schedule an exam with their eye doctor immediately.
