After fully examining your eyes, your optician will discuss what type of glasses, if any, you require. Based on your eyes, your lifestyle and your visual needs, they will help you decide which lens solution is best for you. Below is a brief description of the main lens types we provide. The staff at Deirdre Cooke Opticians will be happy to discuss these options further with you to ensure your spectacles are they best they can be. With our new Essilor Visioffice we can give you an on-screen demonstration of the benefits of all the lens finishes available to you as well as the impact on the quality and comfort of your vision by choosing the correct varifocal for you.
have one power throughout the lens - generally all that is required until over the age of forty.
have an integrated channel where the lens power gradually adjusts from the distance power at the top, through middle distance in the centre to reading power at the bottom. The lens of choice for many who require separate correction for distance and near.
have a distance portion at the top of the lens and a segment at the bottom through which reading is clearer - no clear middle distance area.
eliminate glare by filtering light so it passes through the lens in one direction only. Fully UVA and UVB protective. Less colour distortion than standard tinted lenses. Ideal for driving, water sports and general wear in bright conditions.
reduce the thickness of spectacle lenses. Spectacles feel lighter, are more comfortable and look better also.
for those who cannot wear their regular glasses while playing sport. Fitted with a polycarbonate/toughened lens which is impact resistant, they provide necessary protection from serious eye injuries. Ask any member of staff about cycling, skiing, squash or tennis goggles, just to name a few.
the ideal solution to help avoid embarrasing collisions in the water. Allow you to see as you would with your regular glasses. They give the same protection as your regular goggles. They enable parents to see their children in the water and know they are safe.
Recently we have become very aware of the risk UV exposure poses to ocular health . UV rays are at their most harmful on sunny days but did you know we get more than 40% of UV exposure when not in full sun? Some coated lenses can block between 95 and 100% of UV rays from passing through the front of the lens. However, recent research has shown that UV reflected from the back surface accounts for 10 to 50% of total UV exposure.
The new Crizal Forte UV now also gives protection against reflections off the back surface of the lens. By choosing new Crizal Forte UV lenses, your eyes are 25 times better protected than without any lenses. Now you can have it all - 25 times better UV protection and resistance against the 5 enemies of clear vision:
*Reflections *Scratches *Smudges *Dust *Water
occupational specific lenses designed for computer use and the office work environment in which many of us find ourselves.
give crisper, clearer vision and improve the appearance of spectacles. Remove the visually disturbing reflections which occur when artificial lights (eg: car headlights and strip lighting) reflect on the surface of our spectacles.
clear indoors and automatically darken outdoors. Are excellent for those who are light sensitive or spend considerable time outdoors. 100% UVA and UVB protective - a wonderful choice to protect the health of the eyes.
Lenses fogging up is a frustrating complication of being a spectacle wearer. As well as being a hindrance, the blindfold effect one gets when our spectacles suddenly "fog up" can also be dangerous. Deirdre Cooke Opticians are delighted to introduce the new Essilor Optifog - the best and most durable protection against lens fogging. The Optifog lens is activated by the Optifog Activator by simply adding a drop of this concentrate to each side of the Optifog lens weekly and gently wiping to coat the entire surface. The result is fog-free vision for up to one week.
