Your special needs and preferences will be taken into consideration when choosing frames and lenses.

As independent Opticians, we at Sheehan Opticians are free to select the best lenses suitable for you from any manufacturer. There are many new developments in spectacle lens technology including thinner and lighter lenses, a variety of special lens coatings, light sensitive lenses and lots more-all designed to improve your vision and make your spectacles more comfortable to wear. We are specialists in Essilor, Zeiss and Hoya lenses to name but a few.

Single vision lenses

A standard lens with the same power throughout the lens.

High index lenses

A thinner and lighter lens option for those with higher spectacle prescriptions. Spectacles feel lighter, are more comfortable and also look better.


These lenses are also known as Multifocal or Progressive lenses. They offer superb convenience, combining distance intermediate and reading glasses into one pair of spectacles. Tailor made or customized varifocals are available at Sheehan Opticians using the latest digital freeform technology.


Bifocals combine distance and reading glasses together using a segment near the bottom of the lenses for reading. Unlike varifocals, they do not cater for middle distance.

Photochromic/Transition lenses

Photochromic or Transition lenses darken in response to exposure to sunlight or UV rays and change back to clear lenses when indoors. They offer 100% UVA and UVB protection.

Polarised lenses

Polarised lenses are a fantastic addition in sunglasses, completely eliminating glare and offering 100% UVA and UVB protection. They are ideal for any sunglass wearer especially anyone who enjoys fishing and sailing.

Polycarbonate Lenses

This impact resistant lens material is lightweight and tough. Polycarbonate is the lens material of choice for safety eyewear and sports goggles.

Lifestyle/Occupational Lenses

Occupational specific lenses are a fantastic solution for office workers who spend long periods working on computers at intermediate and close distances. Occupational lenses offer a longer working distance than standard reading glasses.

Anti-Reflection coatings/Tints

Anti-reflection coatings are a wonderful addition to all spectacle lenses, eliminating distracting surface reflections and providing sharper, clearer vision especially around artificial lights. They are a great advantage for driving at night towards car headlights or when working on computers.
Don't forget to ask us about the 'Optifog' range of lenses which are great for people who find their glasses fog up as they move from cold to warm environments and vice versa.

Scratch Resistant Coatings

Most people choose plastic lenses because they are lighter than glass and less likely to break. However, plastic scratches more easily than glass. So to prolong the life of your spectacle lenses, we recommend a scratch-resistant coating.
