      spectacle lenses 

The technology behind the manufacturing of lenses today is highly sophisticated. The same Anti-Reflection coatings on your glasses are used on cameras, microscopes and aircraft/helicopter instruments panels. Polycarbonate lenses are made of the same material used in space helmets, aircraft windshields and compact discs.

 

 

Types of Corrective Lenses:
Single Vision:  Single vision lenses provide corrections with only one focal point. They correct hyperopia (farsightedness) myopia (nearsightedness), or presbyopia including the condition of astigmatism.

 

Half Eye and Reading Glasses:  Half eye spectacles have plus or magnification lenses for near vision, and are generally worn towards the end of the nose.  This allows the patient that needs no correction for distance vision to look over the top of the half eyeglasses for clear distant vision.

Computer Glasses:  Computers are part of almost every phase of modern life, from schools to offices to homes.  Computer users have special visual needs, ranging from glasses that focus at specific distances to special tints to reduce visual strain from staring at a computer screen all day.   Ultraviolet protection is also helpful for computer operators.

Multifocal:  Multifocal lenses can be divided into two categories: (1) lenses with lines and (2) lenses with no lines. Lenses with lines provide a definitive division of powers within the lenses. In lenses with lines, there is more than one field of view depending upon the type of lens. The top portion above the line allows you to see distant objects while the portion below and within the line or segment corrects near vision. Lenses with lines are more noticeable due to the shelf which exists at the segment line.  Multifocal lenses without lines or progressive bifocals are available from over 60 different manufacturers.  Many find this type of bifocal to be more cosmetically appealing since there is no visible between the prescription for distance and near vision.

-----------------------------------------------------------------------------------------------------------------
Kinds of lenses with Lines:
Bifocals:  Bifocal lenses provide two fields of vision, distance and near. There is no correction for viewing at the intermediate distance.


Trifocals:  Trifocal lenses provide three fields of view. In addition to near and distance, a trifocal provides intermediate, arm's-length vision which is usually out of focus with a bifocal lens.


If you need near and distance vision correction, two pairs of glasses are an option. One pair of glasses would use the entire lens for reading and close-up viewing only; the other, to see at a distance.
-----------------------------------------------------------------------------------------------------------------
Kinds of Lenses with No lines:
Progressive Addition Lenses:  Progressive Addition Lenses provide the most natural vision if you are presbyopic. They are cosmetically appealing and attractive in current fashionable frames, because they look like single vision lenses. Vision is clear at all distances. Progressive lenses provide a continuous, gradual change in power from eye-level to the bottom of the lens to achieve the plus or add power the prescription requires. These lenses are especially effective when working on a computer.

Different Lens Materials:
Polycarbonate Lenses:  Polycarbonate is the strongest, safest, lightest and thinnest lens material available. It is more impact resistant than glass, conventional or high index plastic and includes ultraviolet protection and scratch resistant coating. Polycarbonate can be ordered in a variety of fashion tints.  Polycarbonate lenses is always the lens of choice for children or anyone participating in sports or maintaining an active lifestyle (such as police or fire personnel).

High Index Plastic: High Index Plastic is lighter and thinner than conventional plastic and glass. It is more impact resistant than glass, but less impact resistant than polycarbonate and conventional plastic. These ultra thin lenses are now available in tints, including transition.

Conventional Plastic: Conventional plastic is more impact resistant than glass and approximately half the weight of glass. It may be tinted for fashion or sunwear and is available in transition lenses.

Glass: Glass is tempered for impact resistance, but it is not unbreakable or shatterproof. It is the heaviest lens material, however it is more scratch resistant than conventional plastic or high index plastic. Glass is available in photochromatic lenses and a limited number of tints.
-----------------------------------------------------------------------------------------------------------------
Coatings and Tinting:
Scratch Resistant Coating:  A scratch resistant coating on a lens is a prudent investment. It provides protection against normal scratches on the surface of the lens.  A variety of premium lenses now have factory-applied scratch coating, including all polycarbonate lenses, some progressives and many high index lenses at no extra cost.

Ultraviolet Protection:  The Food and Drug Administration endorses the concept that unseen ultraviolet radiation from sunlight can harm the human eye. It is a health consideration for everyone regardless of age. For that reason, ultraviolet protection should be included in every pair of prescription lenses whether they are for indoor or outdoor use. It is widely believed that UV rays can encourage cataract growth and retinal deterioration. 

Anti-Reflective Lenses:  Anti-Reflective lenses are much like the lenses used on very fine cameras to reduce or virtually eliminate glare or reflected light. AR lenses allow more light to be transmitted to the eye, and the wearer sees things brighter, clearer and with crisper details. These lenses eliminate ghost images common to driving at night. They also enhance personal appearance by eliminating distracting reflections for both the wearer and the viewer. This can be combined with various tints to create a night vision lens of impeccable quality.  This is the coating of choice for those who want the best possible vision and the best appearance.

Photochromic lenses:  Photochromic lenses are glass lenses that darken when exposed to direct ultraviolet sunlight. Their changeable tint provides comfort from glare in any light, but their use as a sunglass is limited, especially behind a tinted windshield.  Photochromic glass lenses maintain their darkening and lightening abilities for the life of the prescription, which is normally two years. These are especially useful for someone who frequently goes from indoors to outdoors during the day.

Transition lenses:  Transition lenses are plastic lenses that darken when exposed to direct ultraviolet sunlight.  Not intended as a sunglass, they provide changeable tint that offers comfort from glare.  With the newest technology in transition lenses, they too maintain their darkening and lightening abilities for the life of the prescription, which is normally two years.  .  With new advances in technology,  the properties of this type of lens are continuously being improved.

The NEW Contact Lenses: The biggest advance for the new millennium in both soft and rigid lenses has been the improvements in the manufacturing process.  New lens materials now allow a greater amount of oxygen to be submitted through the contact lens material to the cornea.

PRESCRIPTION SUNGLASSES

If you wear spectacles you need a  pair of Prescription Sunglasses for the sun. The choice of lenses available are numerous and therefore the most common forms are listed below.

 

         Plastic lenses with UV treatment and tint

         Glass lenses which change with the sunlight (Photochromatic)

         Plastic lenses which change with the sunlight  (Transition)

         Polarized  lenses are the choice of many patients today because of its unique characteristics.  Conventional sun lenses reduce visible light but offer little protection from reflected glare (reflected or bounced light produced by sunlight on water, snow or any shiny surface)  Only polarized lenses block reflected glare.

 

All the above are available in Single Vision, Bifocals and Progressive  (no line bifocal).
