Arriving at Heathrow from JFK recently, I discovered that my prescription progressive sunglasses were missing. They were simply gone without a trace and, despite follow-up with ‘Lost Articles’, beyond retrieval. I felt both guilty and reckless as I had no back-up.

It was tempting as an act of penitence for losing track of an expensive item, to replace them with something from the tourist kiosk or even go cold turkey for the duration of my trip. My most important travel accessory – quality sunglasses – were nowhere. This loss was more than a fashion thing, it was a vision thing.

Adequate protection from harsh and deteriorating effects of the sun’s ultra violet (UV) rays, a form of radiation, is critical for healthy vision. The effect of UV rays is cumulative, so it’s important to protect your eyes throughout your life.  

Older eyes are particularly susceptible as exposure to the sun contributes to cataracts, which cloud the lens of the eye resulting in blurred vision. It’s estimated that 20 per cent of cases are the result of extended exposure to UV rays.

Macular degeneration, resulting from UV exposure that damages the retina and in turn destroys central vision, is a primary cause of vision loss after age 60. That UV exposure can speed up a nasty process you may be unaware of, so grab those sunglasses!

Glaucoma is a serious eye disease that affects the optic nerve and can cause irreparable vision loss. Not surprisingly, it too is associated with aging. Sun glare can exacerbate the disorder, so quality sunglasses with polarised lenses are a must on sunny days and when you’re around water or in sand or snow conditions.

The thin, sensitive skin around the eye is very wrinkle-prone, so you’ll want to protect that delicate area from the sun’s harmful rays – even on cloudy days when UV rays still abound.

What to look for in quality sunglasses

You’ll find quality sunglasses at all price points, so don’t be drawn in by expensive non-prescription glasses being the best. Instead, look for:

• Sunglasses that block 99 to 100 per cent of UVA and UVB rays. Mirrored coatings may add some additional protection by further reducing the amount of light that enters the eye
• Make sure your sunglasses block out light with this simple test: with your glasses on, if you can see your eyes in front of a mirror the lenses are probably too light
• Bigger is better, and wrap-around glasses are best for protection, especially on the water. Boaters and fisher-people beware!
• Polarised lenses are critical if you’re doing a lot of driving, boating, or in beach or snow conditions – or if you’re combating glaucoma. Remember, polarisation is not the same as UV protection; you need both.
• A quick quality lens check: holding the glasses at arm’s length look through them at a straight line in the distance, such as the edge of a window frame. If the straight edge distorts, curves or moves, the lens is defective. Move on.

Prescription sunglasses

If you, like me, wear prescription glasses for distance and/or reading, having progressive correction sunglasses is one of those instances where a luxury becomes a necessity. Don’t leave home without a copy of your eyeglass prescription tucked away in your carry-on!

It’s always a good idea to carry a second pair as well, or carry a ‘cover pair’ of sunglasses. A clever cover for your regular prescription glasses will give you the UV protection you need – and polarisation – for a fraction of the cost of specialised prescription glasses.

Non-prescription sunglasses

Again, choices abound. You can buy sunglass ‘readers’ at standard magnifications up to three times magnification. Stylish and very price conscious, these are the best bet if you don’t need a prescribed correction.

A few final thoughts

• You’ll want to wear sunglasses even on cloudy days, and always at midday when the sun’s rays are the strongest.
• The UV light is most powerful at a higher elevation and at the equator – so always, always keep your sunglasses close at hand in the tropics as well as on the slopes
• Keep to this rule of thumb: if you’re outside long enough to get a sunburn, wear a wide-brimmed hat in addition to sunglasses. The extra protection will help block those nasty UV rays.  

See you down the road; I’ll be the one hiding behind the polarised sunglasses!
