Cold Weather Dries Eyes

Low temperatures, high winds and UV light have detrimental effects on eye health

“We all know our lips dry up when we are in  a cold environment, but some people don’t know their eyes can dry out too”, says Chris Miller of Cambridge-based Altacor, a specialist ophthalmic products company.

Low temperatures and icy winds can dry out our eyes causing them to water as our tear glands try to compensate. Chris continues “We recommend wearing protective glasses or using lubricant eye drops without preservatives”. The multi-use 0.5ml vials of Clinitas Soothe are perfect to carry alongside your lip balm on a cold day.

However, it isn’t just the cold temperatures that will affect our eyes this winter. The World Health Organisation warns that fresh snow can reflect as much as 80 per cent of the ultra violet light that hits it. This exposure is much greater than the 15 per cent reflected from a warm sandy beach.

Additionally, a study published in Investigative Ophthalmology & Visual Science found that cold weather could compromise the eye’s lipid film, even in healthy individuals with no previous dry eye problems. This demonstrates that regardless of how healthy our eyes are now, they need more protection in colder weather.

Chris says a drop in temperature, combined with increased exposure to UV light can cause damage to our eyes.

“The outermost layer of the eye’s lipid film is responsible for protecting the corneal epithelium against the evaporation of aqueous tears. When the temperature of this layer starts to fall, oily components of the film cause it to shrink and become stiffer. This significantly reduces the lubricant properties of the film, and as the temperature decreases, these changes become more and more severe.

“Even people without any history of dry eye can be significantly affected by these conditions, so those individuals who regularly experience dry eye symptoms need to take extra preventative care in the cold weather. Using a gel before they go to sleep, can help improve the quality of their tears.”

Mild symptoms of dye eye include: dry, gritty or sore eyes, red eyes and eyelids that stick together when you wake up. If the condition is allowed to develop, more severe symptoms can develop such as extreme sensitivity to light, very red and painful eyes as well as a deterioration to your vision.

As a precaution, Chris suggests wearing protective glasses outdoors and using Clinitas Soothe to help keep the eyes refreshed. Bathing the eyes when you get home and gently massaging them to stimulate the oil producing glands can also help.

Using preservative-free eye drops is safe even if you are on other medication or wear contact lenses. Clinitas Soothe has a high concentration of sodium hyaluronate, which provides a long period of relief. It also comes in resealable vials ready for a quick application as needed throughout the day. Clinitas Soothe is available from opticians and pharmacies nationwide. The sister product Clinitas is available on prescription from your doctor.
