A DO's desk

In other words, how do you choose what you want:
We strongly believe that you are here at our website, because you want the right pair of glasses that works best for your visual needs.
The perfect combination of frame and lenses make a good pair of glasses. I will explain in simple steps that will help you choose the right pair of glasses.

• Know what you need your new glasses for.

Stage 1: Frames
See the frame you like and make sure it is not vastly different to the size of your existing glasses if you have one.

• Like a style.
• Check the size.
• See what material and make sure if you are okay with it. For example, not allergic to metal-alloys. At Specsonweb, you have the Titanium coated range which are Hypo-Allergenic.
• Look at the hinges.
• Look at the Nose Bridge area and make sure you are happy with the design.

Stage 2: Lens purpose
Select the job that your lenses must do. For example, do you need your lenses to work for reading, distance, intermediate, or combination of duties. Below are the details:

• Reading means - most commonly anything you read within 60 cms from your eye. Examples include reading a book, iPad or any tablet, laptop and so on.
• Intermediate means - Working distance of the lens is between 60 cms to 100cms or 1 metre in most cases. Some duties of such distances include reading music notes from a stand, desktop VDU monitor, Using multiple screen (eg: traffic controller) and so on.
• Distance means - Watching TV, Driving, theatre, a football match and anything that you must see beyond 2 metres.
• Multifocal lenses - work for more than one distance. You can use them for reading and distance without taking them off. They are in other words known as Progressive lenses, and this means they also have an Intermediate zone which naturally forms as part of the manufacturing process design. These lenses do not have any lines dividing them.
• Bifocals - as the name suggests, these lenses have two areas, and you can choose what two purpose you need to use each zone for. Most used for Distance and Reading.

Stage 3: Lens designs
Based on the points we discussed in Stage 2, now you will be able to decide what lenses you want.

• Single purpose - Single vision
• Double purpose- Bifocals
• Combination of 3 visual needs - Multifocal designs

Stage 4: Coatings and treatments
This is where, you will select what treatments you will need on the lenses. I will go through the most common treatments that are recommended.
Multicoat Anti-reflection - This is a coating that allows more light to pass through the lens. A normal lens has 92% light transmission factor (LTF), however and MAR lens has 99% LTF.
Transitions or Reactions or Photochromic or Colourmatic or Umbramatic - All these terms mean that the clear lens turns into a darker lens when Ultraviolet light reaches the lens. Different companies have different terms and some of them are classified based on their transitioning time.
Here at Specsonweb (SOW), we sell the Transitions brand which are one of the best lenses in the market.
Or
You may want to choose Polarised lenses - These are dark sunglasses made slightly differently. They have a filter in the lens that blocks the horizontal light passing through. A good analogy is your horizontal Window Blinds and how they offer comfort when they are partially open. These lenses cut off 100% of the destructive glare that you experience.
