We often feel we look sophisticated in sunglasses and we might find they also help us enjoy bright sunshine, but quality eyewear of
all types can actually help maintain healthy eyesight.
Light contains ultraviolet (UV) rays and while it’s invisible, its effects certainly aren’t. Apart from putting our skin at risk, it has the same
effect on our eyes, particularly the crystalline lens within. UV can cause cataract’s, for which the only solution is to surgically remove
UV is most intense in bright sunny weather, especially at the beach or in the mountains, but up to 80% of solar UV radiation can penetrate light cloud cover, so its effects are still damaging. In fact 40% of our exposure occurs when we’re not in full sunlight.
It isn’t difficult to protect yourself against UV rays though. Crizal UV lenses from Essilor have an Eye-Sun Protection Factor (E-SPF) of between 10 and 50, depending on your choice of lens. An E-SPF of 25 for example, means your eyes are 25 times more protected than without eyewear.
Crizal Transitions Signature, fast-darkening, fast-lightening, plastic photochromic lenses, also remove 100% of UV.
Polarising lenses cut through glare and offer complete protection too. They are available for single vision and Varilux lenses and are perfect for driving.
Essilor lenses are available in our Cardigan, Pembroke Dock and Narbeth branches call in now to speak to one of our dispensing opticians for more details.
