A quality Ophthalmic lens is of paramount importance to provide maximum clarity of vision.
The simplest form of spectacle or contact lens is the single-vision lens, made to a single prescription to correct a particular eyesight problem. Concave lenses are used to correct short sight and convex lenses to correct long sight. Concave lenses are generally thinner in the centre than they are at the edge and convex lenses are usually thinner at the edge than at the centre. The curvature of the lens, its thickness and weight will depend on the amount of long or short sight it is designed to correct. The lens material will also influence the thickness and weight of your lenses, as will the size and shape of the spectacle frame you choose. Traditionally, spectacle lenses were made of glass but most lenses are now lightweight plastic and there is a wide range of materials available to suit your prescription and lifestyle. We offer free single vison lenses (1.6 MAR, with anti-reflective coating) on our Alain Mikli, Oliver Peoples Glasses and Tag Heuer Glasses brands.
High-index and Aspheric Lenses
If you need high-powered lenses you can improve the weight or appearance of your glasses with special lens materials and designs. High-index materials and aspheric designs mean that lenses can now be made thinner, lighter and better looking than traditional lens types. High-index materials make lenses for short sight thinner, while aspheric designs that minimise the amount of material make lenses for long sight both thinner and lighter.
Whatever your prescription, it is important to protect the eyes against excessive ultraviolet (UV) radiation. Protection is needed to avoid reflected light from sand and snow or if you spend long periods out of doors, particularly in the summer. Prescription sunglasses can be made with single-vision, bifocal or varifocal designs to offer the same standard of protection as non-prescription sunglasses.
Safety, Sports Glasses and Goggles
Special lenses and frames incorporating eye protection are available for a variety of safety and recreational uses. We stock a range of snow goggles to suit various needs and prescription options. Find out more about prescription ski and snowboard goggles below.
Spectacle lenses can be provided with anti-reflection coatings which virtually eliminate distracting reflections off the lens surfaces. Reducing reflected light is particularly helpful for computer users and for night driving. Anti-reflection coatings also improve the cosmetic appearance of your glasses and can make thick lenses look thinner.
Scratch-resistant / Hard Coating
Plastic lenses are lighter than traditional glass lenses but they scratch more easily. Scratched lenses can be irritating for the wearer and look unsightly. Scratch-resistant coatings are available to protect against damage and prolong lens life.
What Are the Options?
Depending on the type of prescription you have, how much you what to spend and how much hassle you're willing to put up with; there are prescription options to suit any optically-challenged skier or snowboarder.
OTG (Over the Glasses)
Compatible with: Oakley L-Frame, Bolle X9, Bolle Y6, Bolle Boost
The idea behind OTG goggles is to accommodate those who prefer to (or are forced to, due to the type of prescription) wear glasses while skiing or snowboarding. The goggles are designed to be slightly deeper and a little wider and can have that 'oversize' appearance on smaller faces. They also have cut-out sections in the foam, in order to accomodate the frames of the glasses. However, the convenience they offer is great: there's nothing special to them, they just go on over your existing glasses. Downsides are, that two extra glass surfaces inside your goggles means a slightly higher chance of fogging (especially since your glasses may not have anti-fog coating on them, whereas your goggles probably will).
Ideal for: Those who have to wear glasses and don't want to spend extra on any other method.
The Bolle Boost OTG and Oakley L-Frame OTG Goggles are designed to fit most prescription eyewear
Compatible with: Anything!
If you're a contact lens wearer, obviously you have the easiest option - wear your contacts as normal and put your goggles on like anyone else. There are a few things to be wary of though: When in the mountains, the air is often very dry compared to lower altitudes. This can dry out your lenses more quickly (which gets very uncomfortable), especially if you ski in sunglasses rather than goggles. Eyedrops may be a good idea if you find your lenses are getting really dry.
Due to the possibility of the lenses coming out of the eye (again, usually when skiing in sunglasses - wear goggles!) daily lenses are usually a sensible option when skiing or snowboarding.
Ideal for: Those who are already contact lens wearers, or want to be.
With contact lenses, you're free to choose any pair of goggles you like - including these Oakley Crowbars
Compatible with: Adidas, Bolle
Since it's not possible to glaze the entire one-piece lens when it comes to goggles, adding prescription can be achieved by the use of inserts. These sit between the lenses and your eyes and are held in place by fixing to the goggles themselves. They're a lot more discreet than wearing glasses under your goggles, from the outside others will hardly notice them (especially if you have a mirrored or darker lens). Inserts are made of polycarbonate to ensure they're strong, lightweight and optically correct.
Ideal for: Those who can't wear contacts, or find their glasses are fogging up when using OTG goggles.
Prescription inserts work well for those who can't wear contact lenses. They're comaptible with the entire Adidas and most of the Bolle goggle range, including the excellent Adidas ID2 Pure (pictured).
