Contact lenses for hay fever  which are only worn while sleeping provide short-sighted hay fever and other allergy sufferers with an excellent new alternative to traditional daytime contacts. Some 95% of hay fever sufferers are allergic to grass pollen which has a season lasting from May through August and typically peaks around Wimbledon fortnight. With ‘Murray fever' building amongst UK tennis fans, it is worth noting that Andy's potential Final opponent, Novak Djokovic, is a hay fever sufferer and has the additional problem of being a daytime contact lens wearer. When the pollen count is high, daytime lens wearers can experience high levels of discomfort as pollen gets trapped between the contact lens and the eye.

This is where the new ortho-k corrective contact lenses for hay fever  offer an effective treatment for correcting short-sight as well as ensuring allergy sufferers can deal with the difficulties posed by high pollen levels - especially when these are exacerbated in major cities by environmental pollution which also peaks during summer months. The custom-designed ortho-k lenses gently flatten the surface of the eye using the mild pressure of closed eyelids during sleep so that light will focus directly on the retina rather than in front of it. The effect lasts for over 24 hours so the overnight lens wearer has perfect natural vision all day long from removing the lenses each morning through to reinserting them at night.

In 2012, leading allergy expert, Professor Jean Emberlin, (director of Pollen UK, the UK pollen monitoring and forecasting service) published "Hay Fever and Sport", a report sponsored by Care Allergy Defence which highlights how hay fever can adversely affect sports performance, especially young sports participants given that nearly 40% of teenagers are affected to varying degrees by hay fever. He pointed out that one sneeze closes the eyes for a full second as well as upsetting synchronisation and timing, whilst for severe sufferers, nasal flow can be impaired by up to 80% with obvious adverse impacts on breathing and cardiovascular performance. Again, by using overnight contact lenses for hay fever , short-sighted sports participants who are sufferers can achieve perfect natural daytime vision without being restricted on choice of allergy remedy such as eye drops.
