FAQ's - VisionforSport
Q: How do I get my prescription?
A: After your eye examination your Optician is legally obliged to give you a copy of your prescription. Your prescription must be no more than two years old.
Q: Can I have varifocal sports spectacles?
A: It is perfectly possible to have varifocal wrapped sports spectacles but we do not supply them online. Centration of a varifocal lens is critical in both the horizontal and vertical planes to achieve optimum vision and this requires a face to face appointment for additional measurements. We cannot satisfy our professional standards using default measurements as some other online suppliers may do. We would be very happy to look after you at one of our practices in Somerset if you are able to visit us.
Q: What sports frames are right for me?
A: Most frames can be considered as multi-functional in that they are suitable for a variety of sporting activities. Active sports will benefit more from a wrapped style of frame which provides better overall light protection plus physical protection against wind and dust. A flatter style of frame (leisure wear) may be adequate for more gentle pursuits such as hiking and fishing or as a standard sun spectacle.
Q: Should I choose single vision, bifocal or varifocal lenses?
A: Most dynamic sports where you are moving about on your feet are performed better with single vision lenses. Bifocal and varifocal lenses are beneficial for cycling if you struggle to read your Garmin. Golf is played better with single vision lenses, although you may struggle to mark your card. Please refer to the flow chart on the Bifocals vs Single Vision page for an overview. N.B. We do NOT supply varifocal lenses on line. You would need to visit us in practice for additional measurements.
Q: What do you mean by Direct Glaze/Inserts?
Direct glazed is the technical name for a ‘normal’ pair of sunglasses, where the prescription lenses are fitted directly into the frame. Sports spectacles usually have a wrapped lens to curve around the face, providing protection against wind, dust and light. The wrapped prescription lenses incorporate the latest technology to give wide fields of clear vision. Direct glazed lenses are not interchangeable, so it’s important to choose the correct tint type for your sport i.e. light reacting, polarised or fixed tint.
Insert styles are frames which have an optical Insert, made to your prescription. This Insert clips to the back of the frame behind the tinted surface lens. The colour of the surface or top lens can be swapped depending on how bright the lighting conditions are. A wide range of prescriptions can be supplied with Inserts especially if we utilise thinner lens materials (optional extra).
Visionforsport Insert lenses come as standard with scratch-resistant coatings. Anti-reflection coatings improve clarity of vision and can be added as an optional extra.
There is more information on the Inserts vs Direct Glaze page with regards to advantages and disadvantages.
Q: I normally wear varifocals, can I wear a bifocal Insert option for cycling?
A: Certainly. With cycling, you predominantly look down the road with an occasional glance down at your Garmin so there is no requirement for an intermediate focus. This means that cyclists usually adapt very easily to a bifocal lens when cycling.
Q: Are polarised lenses better for skiing?
A: The jury is out a bit on this. Polarised lenses cut down reflected glare from the snow so are visually comfortable to wear in snowy conditions. This may however make it difficult to see changes in surface contours. It is personal taste; Adrian has used both polarised and fixed tints and been happy with both options.
Q: Can I wear varifocals for golf?
A: We would advise against wearing varifocals for golf because there is always slight peripheral distortion, which affects the reading of the green with putting. Some people also feel a little light-headed during the swing with varifocals. The compromise is that you may struggle to mark your card with single vision lenses!
Q: What is my ‘pupillary distance’ (PD)?
A: Sometimes abbreviated to ‘PD or OC’ it is the horizontal measurement between your pupil centres. We need this measurement so that the optical centre of the lens coincides with your pupils, ensuring maximum clarity of vision. Most opticians do not write this information on your prescription as they are not obliged to. However, they do keep your PD on file so all you have to do is call and ask! You can even measure it yourself! Showmehow.
Q: Is there any legal age for buying prescription glasses online?
A: Yes, you have to be 16 years old or over and your prescription needs to be dated within the last two years.
Q: What are the advantages of polarised lenses?
A: When light bounces off surfaces such as water or tarmac you get ‘reflected glare’. This glare reduces image contrast and is very tiring to the eyes. In basic terms, polarised lenses cut out the horizontal reflected glare meaning the lenses provide improved clarity and comfort of vision.
Q: How long will my spectacles take and how much is delivery?
A: Insert options will take up to 10 working days from time of order, but usually they are completed in less time. Specialist Direct Glaze spectacles may take up to 4 weeks. Post and package is charged at £4.75 and your order will be delivered Royal Mail first class, tracked. All spectacles undergo a rigorous quality control check to ensure their accuracy before being posted out to you.
Q: My prescription is quite strong. Will you be able to make it in sports spectacles?
A: With Insert options we can cover a wide range of prescriptions, especially if we utilise ‘thinner and lighter’ lens materials; these are available as an optional extra before proceeding to check out. Direct Glaze spectacles are more limited in prescription range, although the range is increasing with new lens technologies. If in doubt please ring us on 01761 414848 or email us with your prescription details at firstname.lastname@example.org. Should you place an order and your frame and lens choice are not achievable with your prescription, we will contact you and suggest alternatives. On the rare occasions where no alternative is possible or desirable, we will refund your payment in full.
Q: Do your glasses offer the same eye protection as sunglasses?
A: Yes all our products offer 100% UVA/UVB sun protection.
Q: Can you match the tint in my current sun spectacles?
A: If you are able to supply your current tinted lens as a sample, our lens partners may well be able to match it for you. Please contact us if you want this facility and for an idea of additional cost. (01761 414848 or email@example.com)
Q: What are the lenses made of?
A: Insert lenses are typically made of standard 1.5 index plastic with a scratch resistant coating. Thinner and lighter lenses can be supplied with 1.6 or 1.67 index plastic resin materials depending on the prescription. These are optional extras and incur an additional charge. The outer tinted lenses or visors are made of impact resistant 1.59 index polycarbonate material.
All our Directly Glazed lenses are made from impact resistant 1.59 index polycarbonate material.
Q: What tints can you provide?
A: The Insert frame options usually have a choice of outer tints which can be interchanged (see individual frame details). With Direct Glaze lenses, fixed tints come in Brown or Grey with approximately 75-80% light absorption. Polarised lenses have a fixed tint of 85% absorption and are currently available in Brown or Grey. Green polarised lenses may be available shortly. For reacting lenses please refer to the information on the particular product page for these colours and depths.
Q: How do I fit the interchangeable lenses and/ or prescription Insert?
A: Please refer to the videos at the bottom of each Insert product page.
Q: If my prescription changes, can I re-use my Insert and have new lenses fitted?
A: You can buy a new Insert with your new prescription incorporated, whilst keeping your frame. The actual Insert carrier is unlikely to survive being re-glazed and it makes more sense to keep your old Insert as an emergency back-up.
