Swimming Goggle guide
While the range of Swimming Goggles available is vast, ultimately the reason for wearing swimming goggles has always been to help see more clearly in water and above all to protect the eyes from contact with water. The human eyeball isn't designed to see very well in water - light refraction is significantly slower under the surface compared to the air. So wearing goggles will help you see.
If you're pool swimming in any public pool there will be all manner of nasties in the water that can cause irritation. Often the après swim red sore eyes is blamed on chlorinated water but is more often caused as a result the chemical reaction of chlorine and any urine present, the resulting concoction is best to avoid getting in the eyes.
The decision of which swimming goggles to purchase may be based on what swimming you are doing ie: recreational swim fitness/triathlon/race/training/open water. If you do a lot of swimming, whether open water or pool based, you've probably already established your 'go to' type/design of goggles and if you have a pair of favourite goggles then there's nothing to stop you using them in any environment. However, field of vision, comfort and lens type will probably play a greater part in deciding which type of goggles to use for the type of swimming you will be doing.
As the swimming market has developed vastly since the evolution of wearing goggles so too has technology/design/materials so there is now an equally huge choice. So where do you start: Race Goggles, Pool goggles, Open Water Goggles, Goggles for kids, Training Goggles, Prescription Goggles; all provide protection and by helping keep water from your eyes will help you see more clearly when swimming.
Pool Swimming and Swim Training Goggles
If you are swimming for leisure or fitness whether pool or in open water then comfort would be your priority, although for open water swimming the lens type may also be considered (see below). Your choice of swimming goggles should be comfortable and seal well – goggles with a deeper (larger) gasket/skirt designed to seal around the whole of the eye socket are generally more comfortable for prolonged periods of use. Examples include the Aqua Sphere Kaiman Exo, Head Tiger and Tiger Race, Zone3 Attack and for open water swimming Aqua Sphere Vista & Vista Pro, Zone3 Vapour, Cressi Cobra.
Race Swimming Goggles
Generally speaking it's all about low profile/compact to reduce potential swimming resistance (and looking super cool). As a result Race Goggles are generally smaller, some fitting directly in the eye socket or just around the eye socket and worn securely for racing turns but are often not the most comfortable although usually only worn for the short periods of racing. Popular 'race' goggles include Swedish goggles, so called thanks to the Swedish manufacture of the originals back in the '70's. Swedish goggles are fiddly to put together but thanks to the string nose piece have infinitesimal adjustment to achieve a customised personal fit, they are generally cheap due to their simplicity. Current examples include the Head Diamond, MP Chronos, Head Racer. Other examples of racing goggles include the Aqua Sphere Kayenne, Head Stealth, MP Exceed, Zone3 Volare, Zone3 Viper Speed.
Open Water Swimming Goggles
Taking inspiration from scuba diving masks these Swimming goggles are larger – providing a greater field of vision and the skirt will generally cover more surface area (the skin) to provide a much improved seal around the face to virtually eliminate water ingress. Great for Open Water Swimming many with different lens options including polarised, tinted, mirrored – see below. Do bear in mind that salt crystals from sea water and sand are abrasive and will more easily damage plastic lenses – always rinse your goggles after use. Examples includes the Aqua Sphere Seal 2, Aqua Sphere Vista & Vista Pro, the Head Horizon, Zone3 Vision Max, Cressi Planet.
Prescription Swimming Goggles
Many of the larger swim manufacturers now produce Swimming Goggles with Corrective vision lenses. They can be available in kit form so you can assemble the lenses with differing diopters for each eye or available in assembled form with off the shelf corrective lenses pre-installed. Usually available to help with distance vision correction so minus or plus lenses. You won't find corrective lenses in any goggle with a curved lens design due to potential distortion. So check out the Tusa View Opticompo Kit, also available for children requiring prescription swimming goggles and the Tusa View Optical Goggles.
Children's Swimming Goggles
Encouraging youngsters to learn to swim and enjoy being in the water is key and the choice of goggles will play an important part in how comfortable they are in the water. Wearing goggles will also improve their enjoyment and help increase confidence in the water. Some goggles are aimed at younger children and many encompass all ages from 4yrs upwards. Since 2003 we've sold thousands of the Aqua Sphere Seal Kid goggles - they are just so unbelievably comfortable, very accommodating, reliable and suitable for most youngsters up to v approx. 12yrs. Beyond the age of 12yrs it's feasible that some adult goggles may be suitable but if the goggles have to be worn so tight to provide the required seal this will put too much strain on strap and may distort the frame. The incredibly popular Aqua Sphere Kayenne is also available in Junior and Small size (great for smaller teenagers) and ideal for pool use. Other examples includes the Speedo Jet, Cressi Cobra, Cressi Baloo
Does lens Colour matter?
Some competitive pool swimmers will opt for dark tinted and/or mirrored lenses simply to psyche out the competition and likewise they can't then see the whites of your eyes either…! However, remember that anti-fog treatments have a limited lifespan so when this starts to recede combined with dark tinted lenses and you may not be able to see !
Coloured/tinted lenses can make a difference to the clarity of vision in differing light levels and so your choice will depend on what type of environment you are swimming in.
Clear Lenses: for use in any environment but ideally suited to indoor use or in dim light.
Tinted Lenses: Smoke/Dark tinted lenses reduces light transmission to the eye to reduce glare, more so in brighter conditions ideal for outdoor use.
Mirrored Lenses: ideal for bright light conditions outdoor although polarised lenses may be the ideal in bright sunlight. Perhaps a little more about how they look although your opposition can't see you looking at them and vice-versa.
Polarised Lenses: perfect for outdoor swimming to help provide protection by filtering out the sun's horizontal light rays to eliminate glare reflected off shiny surfaces and provide better clarity reducing eye fatigue. Better than a smoke tinted lens for bright outdoor conditions. Some now provide UV protection as well.
Photochromatic Lenses: fairly recent addition to the goggle market but these lenses are tinted but cleverly adjust to a darker lens for greater protection in brighter light and lighten for better visibility in darker conditions.
How Should Goggles Fit
Today's technological advances in materials and design ensures that virtually any google will seal. If goggles should leak during use it is more often to do with how the goggles fit you rather than a fault with the goggle. So how do you know if the goggles fit?
Fit: Position the goggles correctly around the eyes without putting the strap over your head and avoid putting your sticky fingers all over the lenses. Press the goggles gently in to position around the eyes, avoid pressing the lenses although they are plastic it is far better to press the frame on to the face/around the eyes. If there is suction/the goggles stick in place, for a few moments then this is a good indication that the goggles fit and give a good seal. The goggles will pop off after a few seconds because the strap is not securing the goggles on your head.
Strap: The head strap is there to hold the goggle in the correct position on your face/eyes. It is the gasket around the goggle lenses that adheres to your skin to provide the seal. The goggle strap should not be over tightened as this will affect the seal. Squashing the goggles on the face by overtightening the strap will misshaped the goggles and may eventually break the strap. If the strap has a split or is a 2-piece strap, at the back of your head, position one strap at eye level position the other strap higher so the strap secures around the deepest part of your head. This should ensure the swimming goggles are secure.
Adjustability: Many goggles have plenty of adjustment in them to ensure a personalised fit. Easy to adjust head straps with side buckles/clips, rear adjusters, and possibly differing sizes of nose bridge. Goggles which include differing nose bridge size options are great if you have a narrow or wide face. Some race goggles as mentioned above will even have string to given infinite personal adjustment.
Lifespan: If you are a regular swimmer it's feasible that you will replace your goggles fairly regularly, potentially every 4-6 months. Goggles do get a fair amount of abuse. The amount of pressure on the strap/clips and gasket, water pressure on diving in the pool and above all chemicals/chlorine in pools which will gradually degrade plastic/silicone. So the goggles will lose their seal and at that point you would need a new pair.
After Care: Virtually all goggles will have some form of anti-fog coating on the lenses how long this lasts can be very subjective but quite simply the more the goggles are used (and possibly abused) the quicker the anti-fog will wear off.
Avoid wiping greasy fingers on the lenses. Rubbing them with rough skin can scratch the plastic lenses and will damage any mirrored coating. Be aware that salt water, sand and swimming goggles are not a good combination, sandy/salty fingers are abrasive, so don't expect miracles.
- Always rinse goggles in fresh cold water after use – leave them to dry naturally
- Don't leave out in direct strong, bright, sunlight – this can degrade the materials
- Do not rub the lenses this may scratch the lenses and rub off any anti fog coating
- If your goggles come in a case use it to protect and store your dry goggles after use.
