Lens Guide

At Eye Protect we offer a wide range of lens options to suit all types of eyes, prescriptions and uses . When purchasing a frame you have the option to purchase the frame only or package the frame with prescription lenses. To package the frame with prescription lenses, select the lens and other lens features you wish to purchase on the product page. You can customise your lenses by selecting the lens type, lens coating, transition lenses, polarised lenses and lens tinting. You will be provided with a total price for your frame and lenses before entering the checkout. We have included information below explaining the various options available.

 

Lens Options

All lenses are manufactured from high-grade plastic to ensure clarity, durability and lightness. The cost of each lens differs according to the thickness of the lens. The least expensive option is CR39, due to its low refractive index properties. The higher the refractive index, the thinner, lighter and more expensive the lenses are.

 

Standard Thin & Light (1.50)

CR39 1.50 index lenses are manufactured using high-grade plastic and are an affordable choice for daily use. These lenses offer ultraviolet light (UV) protection and come standard with anti-scratch and anti-reflective coatings. These lenses are recommended for use with metal or plastic rimmed frames but cannot be used with semi-rimless and rimless frames.

Sphere (SPH) Range Recommendation: Below +/-1.25

 

Very Thin & Light (1.61)

High refractive index lenses also known as High-index lenses are an ideal choice for higher prescriptions. These lenses offer ultraviolet light (UV) protection and come standard with anti-scratch and anti-reflective coatings. Our 1.61 Hi-index lens range are up to 20% thinner than normal plastic lenses. These lenses are recommended for use with metal or plastic rimmed frames and are the optimal choice for semi-rimless and rimless frames.

Sphere (SPH) Range Recommendation: +/- 1.50 to +/- 3.50

 

Super Thin & Light (1.67)

For the thinnest and lightest lenses, 1.67 High-index lenses are the product of choice. These lenses are designed for people with high prescriptions or those looking for a thinner lens option.

Lens Type

When selecting your lenses, please specify how you use your glasses. This will allow us to provide lenses that are best suited to your prescription and how you use your glasses.

 

Distance Wear

Select this lens type if you require your glasses to see objects clearly at distance. For example sports, driving, watching television or in the classroom.

 

Reading Only

Select this lens type if you require your glasses to see objects clearly close up. For example reading, using a phone/tablet or hobby activities.

 

Computer Vision (Single Vision)

Select this lens type if you require your glasses to see your computer screen clearly. Your computer screen is generally located at an intermediate distance which is greater than your reading distance. Please measure the distance from your eyes to your computer screen and ask your optometrist for the relevant intermediate addition to be included in your spectacle prescription.

 

Computer Vision and Reading (Multifocal/Extended Focus)

Select this lens type if you require your glasses to see your computer screen as well as reading material clearly. These lenses have two different focusing areas, the top of the lens for your computer screen and the bottom of the lens for reading close up. Please measure the distance from your eyes to your computer screen and ask your optometrist for the relevant intermediate and reading addition to be included in your spectacle prescription.

Transitions Lenses (Photochromic)

Photochromic Lenses darken when exposed to ultraviolet light. Once the light source is removed (for example by walking indoors), the lenses will return to their clear state. Photochromic Lenses are designed for indoor and outdoor use. Photochromic Lenses are clear indoors and at night and offer just the right amount of tint outdoors. Photochromic Lenses are offered in the following options:

 

Transitions Grey - Anti-scratch Coating

Transitions Grey - Anti-scratch/reflective Coating

Transitions Green - Anti-scratch/reflective Coating

 

Polarised Lenses

When light hits a reflective surface, such as water, snow, cars and buildings, the light can become polarized, resulting in glare that can interfere with your vision. Polarised lenses are designed to remove glare resulting in comfortable vision, improving contrast, visual comfort and acuity. Ordinary tinted sunglass lenses only cut down on ambient light that reaches the eyes. Ordinary tinted sunglass lenses cannot block glare. Only polarized lenses can block out this dangerous, blinding glare.

 

We supply Polarised Lenses in Grey, Green and Brown tints. Polarised lenses are designed for outdoor use in bright sunlight, especially around water.

 

Tint Type

The lenses you select can be tinted for a specific fashion look or purpose. Tinting can be a full tint which is a full, solid tint across the entire lens in one colour. We also offer gradient tinting where the tint is darker at the top and lighter towards the bottom of the lens.

 

Tints can be ordered in a variety of colour densities. An 85% tint will restrict 85% of light passing through the lens whilst a 65% tint will restrict 65% of light passing through the lens. Therefore an 85% tint is darker than a 65% tint. An 85% tint is recommended for outdoor use in bright sunlight. We offer tinting in grey, green, brown and a variety of other colours.

 

Should you purchase sunglasses with prescription lenses, we can match the tint in the new prescription lenses with the original tint of the manufactures lenses.

 

PLEASE NOTE: If you choose to have your lenses tinted please make sure to select both the Tint Type and Tint Colour on the product page before entering the checkout.

Tint Colours

 

Grey

A grey tint is best used in high sun and very bright situations. This tint does not alter colours as they remain true to their original hue.

 

Brown

A brown tint is popular for use in lush, green areas. It provides high contrast, highlighting reds and greens.

 

Green

A green tint is best for enhancing colours and is good for all round outdoor use.

 

UV Protection for Sunglasses

A UV 400 coating can be added to reflect harmful UVA and UVB ultraviolet rays in the sunlight. Overexposure to ultraviolet light increases the risk of developing cataracts, retinal damage and other eye problems. Adding a UV 400 coating to your tinted sunglass lenses will provide increased protection against harmful  ultraviolet (UV) rays and will not change the appearance of the lenses.

 

Australian Sunglass Standards

All sunglasses sold within Australia are required to comply with the Australian Sunglass Standards AS/NZS 1067:2003. This ensures that you can feel comfortable with the knowledge that your eyes are protected. For specific lens category information, please refer to the Features table on each product page.
