Type of lenses


  • Spherical Lenses


    Spherical lenses are conventional lenses that give clear central vision but can cause distortion the further one looks from the center of the lens which increases as the power of the lens increases.

  • Aspherical Lenses


    Aspheric lenses are thinner and lighter than conventional lenses. In higher lens powers they offer better comfort, a better frame choice and superior optics quality.

  • Aspherical Lenses
  • Digital Lenses


    Digital lenses use advanced digital technology to resurface the lens allowing for greater precision over the entire lens surface. This enables a prescription to be the exact same strength on the very outer edges of the lenses as it is in the middle in a single vision lens. Surfacing the lenses this way provides the wearer with more visual comfort, improved peripheral vision, sharper definition and less eye fatigue. Digital lenses are also called high definition lenses.

    In progressive lenses, this technology allows up to a 20% wider field of vision for both intermediate and near distances. Digital lenses allow more versatility in lens shapes in regards to the prescription so one is not limited in frame style options. Digital lenses are especially suited to patients with high prescriptions and high astigmatism.

  • Personalized Lenses


    Personalized lenses are lenses with curvatures that are specific for the prescription and the frame as fitted to a person’s anatomy. These lenses are individually made, custom lenses that require 6 different measurements to ensure the best vision possible.

  • Freeform Lenses


    Freeform lenses are digitally designed lenses with the curvatures generated for a specific prescription. Each lens is custom made to precise measurements. The result is a lens that requires virtually no adaptation process, give sharper vision by maximizing the optics built into the lenses which provides brighter and more intense colours and can reduce glare and halo effects caused by light sources at night.

    Digital and Freeform lenses are available in single vision and progressive lens designs.

    We use the OptiKamPad system to digitally measure all of the required parameters to dispense digital, freeform and personalized lenses as well as for all of our other lens choices. It has a Frame selection module that allows one to see how they look in different frame styles. The side by side image comparison of up to 4 frames demonstrates frames of different styles so if someone has trouble seeing without their spectacles, they can still see what a particular frame will look like on them before they order.

    The Lens Demo module shows the benefits of different lens designs and how they will affect one’s vision.


    Freeform Lenses
  • Single Vision Lenses


    Single vision lenses correct one focal point or focusing distance. They can be used to correct either distance, near or computer distances.

  • Bifocal Lenses


    Bifocal lenses correct 2 focal points. They are used to correct both distance and near. They do not offer any intermediate vision and therefore don’t work well while using a computer. They do have a visible line in the lens which can cause images to jump when changing between distance and near viewing. Some feel that they are not as cosmetically pleasing as a progressive addition lens.

    Bifocal Lenses
  • Trifocal


    Trifocal lenses correct 3 focal points. They offer distance, near and intermediate focus in a single lens. They have 2 visible lines in the lens and therefore are not as cosmetically pleasing as a progressive addition lens.

    Trifocal Lenses
  • Progressive Lenses


    Progressive lenses correct at many focal points from distance through intermediate to near. This occurs by blending the design. This allows for a gradual increase in power from the distance to the near segment. They are also referred to as multifocal or PAL lenses. Some still call them invisible bifocals but they are not a bifocal by definition.

    All progressive lenses will have a blending zone. This is an area that has very little or no lens power. If one looks through the side of a progressive lens, they will find images somewhat blurred. As the reading power in a progressive lens increases, the field of view in the reading area decreases in a conventional progressive design. Digital and Free form lenses offer larger reading areas in higher reading powers.

    We offer a large selection of conventional, digital and free form lens designs in both single vision and progressive lenses.

  • Progressive Lenses
  • Office Lenses


    Office lenses are progressive lenses that benefit computer users. They differ from traditional Progressive lenses by offering a wide near zone and a wide intermediate zone. They offer proper ergonomics to avoid having to tilt ones head back to see the computer. This can help to prevent neck and back pain as well as eyestrain and headaches. There are different designs of office lenses to account for different working distances in individuals.

  • Office Lenses
  • Anti-fatigue Lenses


    Anti-Fatigue Lenses can help the single vision wearer who develops eyestrain, fatigue, blurred vision and headaches after reading or using digital devices. These lenses give extra reading power at the lower portion of the lens to aid in focusing, thus relieving strain on the eye’s focusing system. They are ideal for students and office workers.

  • Anti-fatigue Lenses

Lens Treatments


  • Scratch Resistant Coatings


    All of our lenses are dispensed with premium scratch resistant coatings. These make our lenses nearly as scratch resistant as glass. Nothing is scratch proof so it is important to take proper care of your lenses.

  • Ultraviolet (UV) Coatings


    UV coatings can be added to regular plastic lenses. Hi index or thinner plastic lenses have 100 percent UV protection built in, due to the absorptive characteristics of the lens material.

  • Antireflection Coatings


    An anti-reflection coating is a very thin film applied to the lens surface. It helps to eliminate reflections in lenses which reduce contrast and clarity, especially at night. It is particularly helpful in people with high prescriptions and those wearing hi index lenses. Hi index lenses can reflect up to 50 percent more light than regular plastic lenses which makes AR coatings essential in hi index lenses. AR coatings make your lenses nearly invisible which is much more cosmetically pleasing.

  • Photochromatic Lenses


    Photochromatic lenses darken when exposed to the sun’s UV light and lighten up again indoors. They are available in all lens materials and designs. They come in an array of colours including, grey, brown, green and bronze. They come in different brand names including, Sensity, Photofusion and Transitions. They do offer 100% UV protection. Photochromatic lenses do not stay dark inside your vehicle so if you spend a lot of time driving, prescription sunglasses are a better option. Photochromatic lenses are also temperature dependent so they will go much darker in colder temperatures.

  • Tints

    Tints


    Tinting a lens can adjust how much light reaches the eyes. A tinted lens an help improve comfort while using a computer, driving or performing outdoor sports.

    Solid tints have the same level of colour throughout the lens. Gradient tints are typically darker on the top of the lens and progressively lighten towards the bottom of the lens to help aid near vison.

    Mirror coatings are designed to reflect glare in bright light situations.

    Double gradient tints are dark on the top and bottom and lighter in the middle. They are a great choice for someone who wants sunglasses that are not too dark but still protect against overhead sunlight and light reflecting off sun, water, snow or sand.

    Yellow and Orange tints improve contrast and are good for low light conditions. They can be helpful for driving in overcast conditions. Amber and brown lenses block large amounts of blue light and are often enjoyed by golfers and outdoor sports enthusiasts.

    Green lenses improve contrast while keeping colours true. Golfers and baseball players often choose green lenses.

    Gray tints reduce overall brightness and keep colours true. They are best used in the brightest light conditions.

  • Polarized Lenses


    Polarized lenses reduce glare that is created when light is reflected off of a horizontal surface such as water or snow. Glare occurs when different amounts of light hit your eyes form varying angles which causes symptoms of strain and can reduce visibility. This can cause problems seeing while boating, fishing, driving or skiing. Polarized lenses block UV light and reduce or eliminate glare. Polarized lenses reduce eyestrain thereby improving visual comfort and clarity.

    Polarized lenses can distort LCD displays in glass cockpits of aircraft and on some motor vehicle displays. They are therefore not recommended for pilots flying modern aircraft.

  • Blue Light Coatings


    With increasing use of digital devices, we are being exposed to higher amounts of blue light. Blue light is known to cause eye fatigue and can cause damage to the retina and the inside of the eye. Blue light coatings filter out the harmful blue light spectrum. Contrast is improved by reducing screen brightness, flickering and eye fatigue.

    We use premium lenses manufactured by HOYA and ZEISS. Our lenses come with a 2 Year warranty against manufacturer’s defects.
