A common mistake that a lot of people make, is not paying attention to eyeglass lens materials, designs and coatings enough!
All opticians provide you with a number of different lenses to choose from, whether you're ordering sunglasses online or customizing them at a physical store - so make full use of the choice provided!
Most good opticians in Sri Lanka - offer the option of glass lenses, plastic lenses, high-index lenses and even polycarbonate lenses - a great selection that may result in you having a hard time making a final decision!
Buying eyeglasses (spectacles or Polar Sun Sunglasses) can seem daunting, but it doesn't have to be. Always feel free to ask support from opticians to help you make an informed choice that you can trust!
