types of lenses

  • Single Vision

    Single vision lenses are ones that have the same focal point all over the lens, meaning either far vision or near vision. They are designed for people who have near or far vision issues. They are mostly used by non-presbyopic wearers. Depending on the type, they have to be removed, if the wearer wants to see at a distance or something up-close.

  • Bifocal

    Bifocal lenses are those that have a clear division of lens; the bottom part of the lens is for reading or near object vision and the upper part of the lens is for distance vision. These eyeglass lenses are highly preferred because they eliminate the need to switch between two spectacles all the time.

  • Trifocal

    Trifocal lens are similar to the bifocal, which means that there are three visionary options in the same lens, near distance vision, far distance vision, and in-between the two distances, that is arm’s length vision. The intermediate vision aspect of the lens can be used to view the computer or read a newspaper.

  • Progressive

    Also known as multifocal lenses, these are lenses that provide a smooth and clear transition from near to far distance. This means the lens has all three vision correction option, near, intermediate and far visionary problems. They are perfect for presbyopic wearers.

types of lens coatings

  • Anti Scratch

    Anti-scratch coating is the treatment of the front and back of a lens with scratch-resistant coating. This hardens the surface so that if there is some kind of contact with the lens, the surface would not become damaged too easily. Such lenses are highly recommended for children.

  • Anti Reflection

    Also known as anti-glare coating, it is very thin multilayer coating on the back and front of an eyeglass lens, which removes the possibility of reflection. This means that your eyes behind the lens will be clear for other people to see. Anti-reflection coating also improves sight in the dark, for computer use and for better reading. Additionally, it prevents reflection when being photographed with a flash.

  • UV Protection

    This treatment of the lens ensures that ultraviolet light cannot pass through and damage the skin or the eye. The coating is made from an invisible dye which completely blocks out the UV light from the sun.

  • Transition

    Transition lens are those that are covered by a thin layer of coating that allows the lenses to become dark when they are exposed to the UV light or the sunlight. These photo-chromic lenses are sensitive to light and when the light source is eliminated, they slowly turn back to their clear state.

Eye glasses can literally change the whole look of your face! And this is the reason why you need to give it a little thought before buying the one that you plan to wear daily. You have two options; either you can ask the salesman to pull out each and every one of the eyeglasses that you find attractive in the shop, or you can learn the science behind which frame fits your face perfectly. This will not only save you time, but will also help you pick out the eyeglasses that compliment your face shape. There are 4 kinds of face shapes: heart, round, oval and square. Depending on the face shape you have, select eyeglasses that highlight the best of your features. There are three things that you need to remember. One, the frame should not be too big or too small compared to your face. Two, it should highlight your prettiest facial attribute, like green frame for green eyes. Three, the shape of the frame should always contrast with the shape of your face.
