Lens Option Details

Lens Type

Non-Prescription

Non-prescription lenses are crafted from clear, plastic and don’t correct vision. We recommend you order non-prescription lenses with an anti-reflective coating for maximum visual comfort.

Single Vision

Single vision lenses are the most common when it comes to prescription eyeglasses. The entire lens is the same prescriptive power. Single vision lenses are appropriate for individuals who are nearsighted, farsighted or astigmatic.

Transitions® (Trademark) or Photochromic (Generic):

Transitions, or photochromic lenses, adjust their shade depending on the light to optimize vision. While indoors, the lenses are clear. Outdoors in sunlight, they darken and mimic the effects of sunglasses. This reduces glare and eye fatigue and eliminates the need for switching between spectacles and sunglasses.

Polarized

Polarized lenses have a filter that blocks horizontal rays of light, thus eliminating almost all glare and reducing reflections. In addition, the lenses filter UV light to protect your eyes. Polarized lenses are particularly beneficial when near water or in the car. Activities, including driving, are much safer. Wearers experience clearer vision, crisper colors and enhanced visual comfort. Polarized lenses work in both prescription and non-prescription sunglasses, even if you require bifocals.

One of our favorites is Essilor Xperio®, polarized sunwear that provides more comfort and protection than tinted lenses. While ordinary tints reduce brightness and offer UV protection, if properly treated, only Xperio® ensures no glare, enhanced clarity and the ability to see colors as they were meant to be seen. As an added bonus the lens color does not fade over time.

The model completely blocks out UV rays for 100% UVA/UVB protection to stave off damage to your vision. Dangerous glare is a thing of the past which makes driving safer. In fact, a recent clinical study measured driver reaction times for Xperio® polarized lenses versus ordinary tints and discovered reaction times were improved by 1/3 of a second. If a car is traveling 50 mph, 1/3 of a second allows the driver to stop a vehicle 23 feet sooner.

Progressive

As we age, presbyopia, or difficulty focusing on objects up close, often sets in. Traditionally, individuals whose vision was impaired both near and at a distance, had to resort to bifocals or purchase a pair of reading glasses in addition to their regular glasses. Peering over the bifocals can cause an image jump and switching between spectacles is inconvenient.

Progressive lenses offer a more natural, smooth correction of presbyopia without the lines inherent in bifocals. The multifocal lenses allow you to seamlessly switch between seeing far away, at an intermediate distance and up close.

The Spectacle Shoppe carries a variety of progressive lenses, such as the Essilor Varilux S, with more stability of vision in motion, which reduces the swim effect by up to 90-percent, faster visual reaction time, and binocular fields that are up to 50-percent wider than the standard progressive lenses.

Bifocals

Bifocals are the original answer (Benjamin Franklin is credited with having invented them) to the need for different focal lengths. They are typically prescribed to individuals with presbyopia, the inability to focus up close, who also experience myopia, or the inability to see objects clearly at a distance, or astigmatism. Nearsightedness and farsightedness can be corrected with one lens. There is a visible line separating the two visual fields.

Lens Thickness

Mid to high index lenses allow for extremely effective light refraction in a thinner, lighter lens. The higher the index, the less material is needed to correct refractive error. These lenses are recommended for those with moderate to high prescriptions. A refractive index of about 1.50 is the standard for regular plastic lenses. So how do you choose the best lens for your prescription? We break it down below:

Lens Coating

While no lenses are completely scratch proof, anti-scratch coatings are an excellent investment as they prevent minor scratches on your lenses.

Anti-glare coating, also known as anti-reflective coating, is a multilayer coating that reduces undesired reflections on the front and back of your lens. This allows people to see your eyes, as opposed to their own reflection. It also increases transparency for better clarity of vision, making it perfect for activities such as night driving and computer use.

Most coatings on the market serve a variety of functions including:

Always choose the highest quality coating options within your budget. This will ensure your lenses offer optimal performance and durability. A basic coating won’t resist dirt and smudges as effectively as a higher end coating, yet any coating is better than no coating at all.
