Spectacle Lenses

When your spectacle lenses prescription is determined the optometrist will explain your prescription to you and advise you on the best type of lenses for the job.

Single Vision lenses have a single focus and can be used for reading or for distance vision correction.

Bifocal Lenses combine distance focus with a reading segment inserted at the bottom of the lens. There is a definite line between the two parts.

Progressive Lenses are designed to blend the different focal areas and so there is no line. The power of the lens changes gradually from distance at the top to reading at the bottom so that it takes in the middle distance also. There are different types of progressive lenses which cater for a variety of occupational requirements.

Lenses can be made in high density or thinner materials to enhance comfort and appearance. There are coatings and tints which can improve visual performance. Polycarbonate lenses are tougher and suitable for safety spectacles.

Tinted lenses for sun with UV filter are available in a variety of colours and densities. Photochromic lenses which darken in the sun can be made in single vision and multifocal prescriptions. Polarised lenses are available in most prescriptions and reduce reflected glare which is ideal for sailing or fishing.
