Single Vision Lenses

These are the simplest form of vision correction and consist of lenses to correct hyperopia (long sightedness) and myopia (short sightedness). Today there are many lenses to choose from, including the latest technology in high index lenses which greatly reduce the lens thickness and weight for those who require high powered lenses.

Bifocal Lenses

Bifocal lenses correct distance and near vision in the same lens with a visible dividing line on the lens separating the two sections. The upper half corrects the distance vision, and the lower half corrects the near vision. Bifocals used to be popular but now multifocal lenses are more commonly used.

Multifocal Lenses

Multifocal lenses are like bifocal lenses in that they correct distance and near vision in presbyopia however there is no visible line through the lens – the power increases gradually through the lens and mimics your own natural vision. Anybody who has worn reading glasses will realise that it can be frustrating when your distance vision is blurred when you look up from what you are reading and look at your computer or across the room. Multifocal lenses allow you to see both what you are reading, your computer and across the room while leaving your glasses on. There is a large range of multifocal lenses including the latest Lifestyle designs from Hastings Optical Supplies. This type of lens uses the latest technology to minimise some of the distortions which were experienced in earlier version of multifocals.

Hi-Index Materials

Use of the latest high-index materials is available in all forms of vision correction. Essentially it allows higher powered lenses to become thinner and lighter than conventional lenses. The lens looks cosmetically more pleasing and because it is lighter, it means that it is more comfortable to wear.

Photochromatic Lenses

Transition is the leading brand in photochromatic lenses. 2020 saw the new release of the Transition Signature 8. Transition lenses are clear indoors at night but automatically adjust their tint according to the level of UV light outdoors. They are convenient as you have both your clear lenses and sunglass lenses in the one frame. They are available in all forms of vision correction.

Coatings and Tints

Coatings control unwanted higher blue end wavelengths of light emitted by our E device screens, combine this with scratch resistant coatings to improve your screen comfort & safety and night vision clarity. And without lens reflections your spec frames appear optically empty. Your eyes can be seen clearly behind your lenses. With these lens coatings and thinner smarter lens technologies you will see and look your best in specs.
