Spectacle Lenses

The lenses you select for your spectacles are just as important as the frames you choose. Our experienced staff can help you get the most suitable lenses for your lifestyle.

As an independent optometrist, we are able to help you select from the wide range of technologically advanced lenses from the top manufacturers worldwide. There are so many lens combinations available now you need our expert advice to make sure you get the most suitable lens, for your needs.

Single Vision
Single vision lenses are used to provide vision correction for patients who are nearsighted (myopia) or farsighted(hyperopia). The lens is made with a single prescription that is consistent throughout the lens. Correction for astigmatism may also be included in a single vision lens. This type of lens is available in all lens materials.
Bifocals
These provide two vision zones separated by a visible line. The bottom segment (often “half-moon” in shape) corrects for near or reading distances while the remainder of the lens corrects for distance vision.
Trifocals
These offer three vision zones separated by visible lines. The upper area is for distance vision, the middle segment provides intermediate vision for distances between 2 and 7 feet, and the bottom segment holds the reading prescription.
Progressives
Also referred to as “no-line bifocals”. These lenses are similar to trifocals in that they have three different prescription areas for near, intermediate, and distance vision. Progressives differ from bifocals and trifocals in that the different zones are not separated by visible lines, but rather offer a natural, “progressive”, transition between the different powers on the lens. This eliminates the problem of “image jump” associated with lined multifocals and presents a more attractive appearance.
Lens Options
Scratch Resistant Coating

When a spectacle lens becomes scratched, it can impair vision through the lens and present an unattractive appearance. Scratch resistant coating may be applied to both surfaces of a lens to help protect against scratches caused by everyday use. This not only increases the durability of the lens, but also protects your investment.

“Scratch-resistance” does not equal “scratch-proof”. Because of this, it is important to handle your glasses with care and always place them in a proper case when not in use. All lenses from Ezekiel Eyes include scratch resistant coating at no extra cost.

Anti-Reflective Coating

An anti-reflective coating increases the amount of light passing through the lens, while reducing the amount of light reflected by the outer surface of the lens and virtually eliminating glare on the inner surface. This benefits the wearer by increasing visual acuity (especially in low-light conditions, such as driving), enhancing appearance, and removing the distracting reflections of ones’ eyes on the inner surface of the lenses.

Polarized Lenses

Polarized lenses act to virtually eliminate glare from flat, reflective surfaces such as water, snow, and roads. They accomplish this by utilizing vertically oriented polarizing filters that effectively block 99% of the horizontally polarized glare from various flat surfaces. This provides the wearer with added comfort and freedom from eyestrain with increased visual acuity. These lenses are available in many different types and materials.

Polarized sunglasses are superior to standard sunglasses. Regular sunglasses help to reduce brightness, but do not always effectively reduce glare. Polarized sunglasses will provide reduced brightness, glare, and full ultraviolet protection. A wearer will also notice that colors appear more natural and accurate with polarized lenses. Polarized lenses are available in single vision, bifocal, and progressive lens styles.

High Index Lenses

High index lenses are chosen for their lightweight comfort and attractiveness. High index lens materials are lighter in weight and thinner than their regular glass or plastic counterparts. The benefit is that if you have a strong prescription, you are no longer forced into “Coke-bottle” lenses.

Just about everyone can get attractive spectacle lenses that complement their appearance, rather than detracting from it. 
High index lenses are made of materials that are compressed, or denser, so the same amount of visual correction is taking place using less lens material than traditional plastic or glass requires.

“High index” means that the lenses are constructed of a plastic or glass material that has a higher index of refraction. The “index of refraction” refers to the speed that light travels as it passes through the lens material.  Currently the highest index plastic lens has an index of 1.74.  Conventional plastic has an index of 1.49
