Common vision disorders

If you have noticed any of the symptoms of the common vision disorders you should book an appointment with us so that we may determine what your condition is, if vision correction is required and the best solution to your problem.

There are 4 common vision disorders that require optical correction:

Myopia: the inability or loss of resolution to see at a distance.

Hyperopia: the inability or loss of focussing ability to see up close.

Astigmatism: the inability to focus at distance and up close due to the irregular or ‘football’ shape of the eye.

Presbyopia: the loss of the ability to focus up close and the loss of ability to adjust focus. Presbyopia  is a natural part of life that affects more than 100 million North Americans. Some people notice the symptoms around age 40 while others may not notice it until later.

Lens types

Eyeglasses or contact lenses are the most common ways to correct vision disorders, but each option comes with advantages and disadvantages that should be discussed with your eye care professional.

Whether you require a distance or near correction, Varshney Optometry offers several different lens options, varying in materials and indexes that are tailored to your frames and prescription.

Regular Plastic 1.50
These lenses are good for lower prescriptions in which impact resistance is not important.

Trivex or Polycarbonate Lenses
UV protected and extremely impact resistant. These lenses are highly recommended for children and are required for sports and as safety lenses.

High Definition Lenses
Unlike conventional lenses, we offer high definition lenses customized to your individual vision needs that provide the largest possible distortion-free field of vision even towards the periphery of the lens.

Computer Vision Syndrome Solutions
Do you suffer from eye strain when using a computer? Computer Vision Syndrome (CVS) is very common as the human eye is not designed for reading from a computer screen for long periods of time. We provide you with lenses that are uniquely designed for working on a computer or texting on a smartphone and will significantly reduce eye strain caused by CVS.

High Index Lenses
Varshney Optometry offers high index lenses and all of these lenses are UV protected. They come in varying indexes 1.6, 1.67, 1.70, 1.74 and 1.80 in glass. High index lenses are recommended for higher prescriptions; the higher the index the thinner the lens.

Photochromic Lenses
Hate having to constantly change your glasses to adjust to varying levels of sunlight? Photochromic lenses automatically adapt to the level of UV; as you move from indoors to outdoors the lenses darken as required providing maximum comfort and protecting your eyes from harmful UV rays when outdoors. There is a now new type of transitional lens that even gets darker in the car.

Myopia Control Lenses
Myovision™ lenses by Zeiss have a unique design indicating a reduction in myopia progression by an average of 30%. These lenses are recommended for East and Southeast Asian children.

Multifocal lenses provide both distance and near correction in single lens usually worn for presbyopic vision correction. Generally, these lenses contain a distance prescription in upper portion of the lens, which transitions to a near prescription in the lower portion meaning that you do not have switch between glasses or take them on or off as your vision requirements change. The size and shape of each portion can be customized to meet on your unique vision needs and preferences.

There are different types of multifocal lenses to correct presbyopia:

Bifocal Lenses
With these lenses you are able to see a visible line. The top portion is for distance and the bottom portion is for near work. There is not any prescription for intermediate or computer work.

Trifocal Lenses
With these lenses you are able to see a visible line. These lenses are much like the bifocal lenses however they have an middle portion for computer or intermediate work.

Occupational Bifocal
With these lenses you are able to see a visible line. These lenses have a top and bottom section for near work and the main part of the lens for distance. These lenses are primarily for certain trades such as electricians.

Progressive lenses are multifocal lenses that provide a more natural solution for distance, intermediate and near correction in a single lens for presbyopia. The distance portion is at the top and it gradually transitions to a near prescription on the bottom.

Conventional Progressives
Allow a very small area for distance, intermediate and near. Commonly you may hear that people have tried progressives and they did not like them as they found that there was a very small area for distance and near, that their peripheral vision was distorted and they found it hard to walk with them on.

High Definition/Free Form Progressive Lenses
High Definition Progressive lenses provide a more enhanced natural vision solution for far, near and in-between. Varshney Optometry offers high definition lenses that provide the widest distance, computer and reading area, free from distortion at all distances minimizing the soft focus areas between far and near. Some free form lenses offer the ability to have the ground view advantage which allows less distortion when walking up the stairs or to see the golf ball while putting and driving. These lenses are made with digital technology but are not to be confused with digital lenses as not all digital lenses have large distortion free zones. Varshney Optometry will suggest the latest in progressive technology with premium high definition/freeform progressive lenses that are the best for your situation.

Lens coatings

To further customize your eye care solution, we offer the following lens coatings:

Anti-Glare/Reflective: Reduces glare and reflection making night driving, television, looking at a computer screen and reading much easier, reducing visual fatigue and enhancing the quality of vision.

Tinting: A variety of colours can be used to tint lenses to reduce glare and enhance vision for specific tasks and can also augment skin tone.

UV Protection: Provide protection from harmful UV rays. UV protection can be incorporated into every lens including clear lenses and is recommended for everyone.

Scratch Resistance: Protection from scratches and smudges.

Extra Hard Lens Coating: Maximum protection from lens scratching similar to glass.

Superclean: Keeps your lenses cleaner. Ideal if you find that your lenses deposit frequently.

UV exposure caused by the strong summer sun and even on cloudy days (as UV is not filtered by the clouds) can not only damage your skin but also can damage your eyes. UV radiation can cause cataracts, AMD, pterygium, pinguecula, photokeratitis and skin cancer of the eyelids. One of the most common complaints from UV exposure are red, watery and dry eyes.

Prescription sunglasses can be customized for almost any prescription and we also offer a large selection of prescription sunglass options for kids.

Some key features to look at when buying sunglasses include:

  • UV Protection demand sunglasses that have 99-100% UV protection. Please check when getting non-optical grade sunglasses. UV protection is an almost clear coating and is available on most lenses.
  • Complete Frame Coverage frames with larger lenses and temples which wrap around the eyes offer greater coverage. However, these frames may block your peripheral vision and may not be possible for all prescriptions.
  • Lens Colour affects depth perception and contrast. Certain colours may enhance this.
  • Darkness choose the intensity that is most comfortable for you. There are even gradient lenses that get lighter towards the bottom of the lens which allows for easier near tasks while wearing the glasses.
  • Polarization blocks reflected light that bounces off of smooth flat surfaces such as water, wet green grass and sand. Polarized sunglasses are extremely important for people who enjoy water sports and fishing.
  • Photochromic Lenses change colour with response to varying lighting conditions so you do not have to switch your glasses.
  • Antiglare Coating reduces reflections from the sun and improves optical clarity.
  • Lens Type Polycarbonate or trivex lenses provide the most amount of impact resistance and are recommended for children, sports and hazardous work. Glass and trivex lenses provide greater optical clarity.

Children up to age 3 will receive a complimentary pair of sunglasses with an eye exam.

By the age of 20


of UV exposure occurs, so it is very important to wear sunglasses from early childhood.
