Types of Lenses & Coatings

At Focal Point we use and recommend only world leading brands in lens optical performance and technology. Although they may look the same as generic lenses to the naked eye, they are certainly not. The technology and precision manufacturing processes that go into producing the lenses is incomparable. For example you wouldn't expect sharp crisp images from a non premium brand of digital camera. The same principal applies to to your glasses lenses.

Choosing the correct type of lenses will depend on your lifestyle and your prescription. To name just a few options; there are high index materials which will reduce the thickness of lenses, various anti reflective and photochromatic coatings which can be applied, as well as tints. Our optometrist can discuss all the options with you

Glass Lenses

Glass lenses are more scratch resistant than plastic but more vulnerable to breaking if dropped. Glass lenses can be chemically harden to make them shock resistant. They are also slightly heavier than plastic lenses.

Plastic Lenses

Plastic lenses are lighter and more impact resistant than glass and are ideal if you work in a rough environment. They are more suited for the sporty and physical type person. Although they scratch more easily, hard coatings can be applied.

High Index Lenses

Chemists have created a variety of new plastic materials that bend light more than the conventional plastic lenses meaning less lens material is required to correct your vision. High index lenses are thinner and lighter than standard regular lenses. This makes your spectacles more comfortable to wear. They are also great if you have a high prescription or have selected a frame where the sides of the lenses are visible.

Photochromatic lenses

Technology is improving all the time with photochromatic lenses. They allow your spectacles to change from light to dark in the presence of ultraviolet light blocking 100% of harmful UVA and UVB rays. They are great for people who frequently spend time outdoors. Click here to find out more

Anti-scratch Coatings

A varnish is applied to both sides of all our lenses to protect them for rigorous day to day use.

Anti-reflective Coatings

We recommend this coating to all our customers. Although there is an additional expense, the coating reduces glare and reflections off your lenses. This increases the amount of light that reaches your eyes and provides brighter, crisper and clearer vision. Click here to find out more...

UV Coatings

When this is applied, the lenses give 100% protection from harmful UV rays.
