Spectacle Lenses Bridgnorth by Liage Opticians
There are a bewildering array of lens options available for the spectacle wearer, all of which are designed for specific prescriptions, frames or occupational use. At Liage we check the lens designs of numerous manufacturers to ascertain if they are both good and value for money.
Examples of lens options are Multi Anti Reflection (MAR) coatings, Photochromic lenses, Bifocal lenses, Varifocal lenses and High Index lenses.
Multi Anti Reflection (MAR) coatings
MAR coatings are designed to reduce reflection on both surfaces of the lens, making it clearer to look through with enhanced contrast. The coatings are also very hard, reducing the susceptibility to scratching. However, if these coatings are of poor quality, they can actually reduce the vision of the wearer and smear very easily. We only supply the better coatings.
Photochromic lenses darken in sunlight to reduce the amount of light the wearer experiences (like sunglasses). However, there are numerous options available which affects their clarity, reaction time and depth of tint. Many multiple optician groups have only one or two (at most) types available, unlike Liage.
Bifocal lenses are for people who require different lenses to see near compared to distance. Put simply the main lens is the distance lens and carrier for the reading portion which is like a small window incorporated into the lens. There are numerous designs of these lenses which have variations in the reading window. At Liage we assess which lens is the best option for your visual demands.
Varifocal lenses are similar to bifocal lenses in that they give different focussing points within the lens, to see both distance and near but also everything in between. There is no window and the focus points are blended into a continuous variation. Most multiple optician groups offer a ‘Good, Better, Best’ option of 3 lens designs (from one manufacturer). When you consider that Liage has over 80 designs available from different manufacturers you can see that the ‘Good, Better, Best,’ does not cover everyone’s needs. We always ask what your visual requirements are and match the best designs to your needs.
High Index lenses
High Index lenses are made of materials that are thinner, and therefore cosmetically superior, for people with high prescription (thicker) lenses. However, designs of the lens curvature and the type of material can have good or adverse effects on the vision. Liage staff have a thorough understanding of the advantages and shortcomings of these lenses and advise based on best results, not on highest prices.
