Lens Technologies

Matching your prescription with the best lens technologies will enable your eyeglasses to meet your demands for vision and style.

Advancements in materials, progressive designs and anti-reflective coatings are a few of the options available to make your eyeglass lenses thinner, lighter, more attractive and more functional. Computer use creates a unique strain on eyes. Many of us experience some degree of dry eyes, blurred vision, headaches, neck ache or fatigue with extensive computer use. Specialized lenses have been created to relax your eyes and provide a variable focus that makes your computer and office work less stressful and more productive.


Sunglasses that offer Style & Protection

Quality sunglasses go far beyond fashion. With lenses to shield your eyes from harmful UV light, polarized lenses to reduce reflected glare, transition lenses to darken according to direct sunlight exposure, Southwest Vision has several options to consider when purchasing your next pair of sunglasses.

Sunglasses are also a very important part of maintaining good eye health. They help protect your eyes from the wind, pollution, and the harmful effects of the sun. They also help protect the skin around your eyes, and reduce the risk of abnormal mole growth.

All sunglasses carried by Southwest Vision are manufactured using the finest quality lenses, specially treated to filter harmful atmospheric ultraviolet radiation.

Southwest Vision believes in adopting the latest technologies available in the vision care industry. The Shamir and EyeZen family of products implement the most cutting edge technologies available today for prescription lenses.

Harnessing today’s cutting-edge technologies, Big Data, and Artificial Intelligence, Shamir introduces it’s most advanced progressive lens: Shamir Autograph Intelligence™ is a continuous lens design that optimally matches the wearer’s visual needs and Visual Age™.

Designed to Match Your Visual Age™

Today’s progressive lenses provide patients with a “personalized” lens based mostly on the measurements of their selected frame, or “customized” based on lifestyle information from questionnaires. This “one design” concept provides everyone with the same solution.

Shamir embarked on an extensive research project using methods of Big Data and elements of Artificial Intelligence. They examined the visual behavior and preferences of presbyopes of all ages, by taking into account their Visual Age™. (Visual Age™ refers to the physiological age of the eye (the required addition) and is generally correlated with the patient’s chronological age.)

Autograph Intelligence™ is their most innovative and intelligent design to date, utilizing 12 unique design concepts to fit the visual needs required for each Visual Age™. Shamir Autograph Intelligence™ closes the gap between visual needs that presbyopes of all ages want and require. This revolutionary progressive design concept has been tailored based on our in-depth research and is relevant to the visual needs of young, mid, and advanced presbyopes.

EyezenTM+ Lenses Defend Against Digital Eye Strain and Harmful Blue Light*
Today’s digital world forces our eyes to work harder every day. Single vision patients need a better solution that can keep up with the modern demands of life and the impact they have on their eyes.

Harmful Blue Light

There are a growing number of sources of Harmful Blue Light
With experimental data indicating that blue-violet light acts as an inducer of oxidative stress on the retina, the demand for blue-violet light protection against retinal pathologies is clear. It is equally clear that when designing ophthalmic lenses, it is imperative that they filter Harmful Blue Light (blue-violet) while also ensuring that the beneficial blue light (blue-turquoise) reaches the retina during the day.

Harmful Blue Light decreases retinal cell’s self-defense systems
Researchers have confirmed that blue-violet light results in increased oxidation in retinal pigment epithelium (RPE) cells. This decreases the cell’s self-defense systems, making them inadequate to compensate for the increase of oxidative effects.

When the retinal cell’s self-defenses are diminished it becomes a fertile ground for highly toxic reactions
In the presence of oxygen, high energy photons can react with photosensitive compounds to produce photochemical reactions. These reactions are highly toxic and cause protein oxidation. This creates a fertile ground for oxidative stress in an environment that is already sensitive to that type of stress.

Blue-Violet light, also known as Harmful Blue light is known to be a contributing factor to AMD Harmful Blue Light can be considered a risk factor for age-related macular degeneration (AMD).

AMD is associated with chronic inflammation and oxidative stress. In developed countries, AMD is the leading cause of irreversible visual impairment, with 17.8 million cases in the US alone.

Digital Eye Strain

Digital Eye Strain is defined as the physical eye discomfort felt after two or more hours in front of a digital screen
A combination of factors including the proximity at which we view digital screens, the frequency and length of time of this use, and physical responses to screen habits, have conspired to cause visual discomfort in 65% of Americans.

Digital Eye Strain originates from the overexertion of the ciliary eye muscles
When focusing on close objects, the eyes accommodate to try and create the clearest possible image. The eye accommodates by flexing the ciliary muscle which changes the curvature of the crystalline lens. Digital eye strain comes from this prolonged contraction or “flexing” of the ciliary eye muscles.

Adults under 30 experience the highest rates of digital eye strain symptoms (73%) compared with other age groups
Adults in their 20s are the ultimate device multi-taskers — these individuals are constantly switching back and forth between different technologies. It has been noted that 75 percent of people who use two or more devices simultaneously report experiencing symptoms of digital eye strain more than people who use just one device at a time.
