Bright Winter Eyes

Protecting our eyes in the winter is essential for preventing short and long term problems.
Eye dryness is very common, especially on cold brisk days. Finding comfort near a warm toasty heater or fireplace can dry the eye surface too. Maintain good eyelid hygiene, stay hydrated and use artificial tears to control mild dry eye symptoms.

Snow-blindness or keratitis is a painful corneal condition that can occur when the outermost layers of the cornea are damaged (like a sunburn). Damage can occur in as little as an hour of exposure to ultraviolet radiation, the risk is intensified at higher altitude.

Damage to the eye doesn’t stop on the surface. Cumulative ultraviolet exposure damages the lens of the eye causing cataract formation. Research has also found that UV radiation contributes to macular degeneration.

Wearing good UV blocking sunglasses protects all layers of the eye. The UV radiation reflected off of water and snowUV and sunglasses is dangerous too.

Don’t hang-up your sunglasses because it is winter, year-round UV protection is a proactive way to promote good eye health and clear vision for adults and children.

New Generation Transition Lenses

Transitions 2014

Tuesday night we left the office a little early to attend a seminar on the newest Transition Lenses. Most people are familiar with spectacle lenses that get dark when you go outdoors, and lighten again when inside.
This newest generation Transition Signature VII lens with Chromea7 technology was created with the user in mind. The Chromea 7 molecule is more reactive to ultraviolet in more situations. It gets darker on hot days, under a tree and facing away from the sun. The new Transition 7 also fades back to clear 20% faster.

Like all products in the Transition Adaptive lens family (XTRActive and Vantage) the Transition VII blocks 100% UVa and UVb. All the adaptive lenses help eyes adjust to changing light levels, providing more comfortable vision.

If it has been years since you’ve tried the transition lenses, it may be time to try them again. This isn’t the same lens your grandfather wore.
