Help with frames & Lenses
Spectacle frames are made in a range of different materials, we believe it is important to give you an insight into what they are made from so you can find the right qualities for you. MyGlassesGuru offer a wide selection of frame materials, providing you with many different options to help you create a completely new look, whether you are choosing Sunglasses or a simple pair of reading glasses.
Plastic frames are great if you want all the colours of the rainbow. Most of our frames are made of cellulose acetate which is extremely lightweight can come in most colours is hypoallergenic so perfect for those of you who find certain frames which cause allergic reactions.
Plastic frames do have a few drawbacks. Over time the colour can fade and sunlight can decrease their strength. They can burn although are not easily ignited and are easier to break than metal frames.
There are many types of metal frames the most common are nickel silver, stainless steel and titanium.
Titanium is a very versatile material, apart from being used as spectacle frames it can also be found in space shuttles. It has qualities perfect for glasses being lightweight, strong, corrosion resistant can be produced in a variety of colours and is also hypoallergenic.
Stainless steel is an alloy of steel and chromium the latter of which gives excellent resistant to corrosion, abrasion and heat. It is lightweight and reasonably priced and although some people can react to stainless steel this is uncommon
Nickel silver is named for its appearance only as it doesn't contain any silver. It is an alloy of copper, nickel and zinc. Nickel silver is attractive for frames due to its sparkling sheen and lower cost than other materials. This material can be more ridged and thus brittle compared to titanium and for people who have allergies theses frames should be avoided.
Once the frames have been chosen it is as important to choose the correct lens type ensuring optimum vision.
Scratch resistant coatings
This coating protects the surface of the lens and will lengthen the life of the lens ensuring sharper, clearer vision for longer.
Anti reflective coating
Anti reflective coatings reduce the light reflections on the lenses from artificial lights such as those from computers or scatter from car headlights thus reducing the glare from computers and allowing night driving to be more comfortable, they also give a clearer view of the eyes through the lenses allowing an enhanced cosmetic look.
Tints have several roles, they relieve eye strain and glare in sunny conditions and sometimes people with cataracts may find a light tint helpful. Most glasses can be made into sunglasses.
Thinner lenses are designed to reduce the weight of the lens cut into the frame thus reducing the pressure of the frame on the face, they also reduce the thickness of the lens giving a better cosmetic appearance. There are several different types of thinner lens and we can advise accordingly when choosing frames.
Polarised lenses are ideal for driving and water sports such as sailing and fishing. They reduce the glare for the sun and improve vision and comfort. They filter out all UV light and reduce horizontal glare by 99%.
Light reactive lenses
These lenses react to light allowing comfortable vision. They also have 100% UV protection. Indoors they are almost clear and outside they darken depending on the level of UV.
Single vision lenses
These lenses are a lens with one prescription either for distance or for reading.
Bifocal lenses have two prescriptions, ideal for people who require glasses for driving and reading and allow the person to wear just I pair of spectacles rather than carry a second pair with them.
Varifocal lenses allow the person wearing them to see three areas of their vision, distance, middle distance and near and look as if they are wearing single vision lenses with no lines on the lens that bifocal exhibits giving a greater cosmetic look.
