The lenses to choose for your glasses depend on 3 factors: most importantly, your prescription. Secondly, frame style of the glasses (i.e. whether it is rimless, full rim or semi-rimless) and finally the purpose of the glasses.

Some lenses are not suitable for Rimless glasses, for example CR39, while Trivex 1.53 or high index 1.67 lenses are perfect choices for Rimless glasses.

If your prescription has high power, high index lenses or ground lenses have to be used otherwise the lenses would be too thick. If your prescription has a sphere that is more than -3 diopter, we do not recommend CR39 stock lenses.

If the wearer is a child or the glasses are to be worn in frequent sports activity, then it is a good ideal to choose impact resistance lenses such as Trivex or high index 1.67 lenses.

Have you ever purchased glasses on the Internet and been frustrated that the lenses fitted to the glasses was too thick or not suitable for your purpose. We have the solution for you. To make your online shopping experience as easy as possible, we have developed lens packages that are suitable for different prescriptions. Separate lens packages have been developed for sunglasses as well as single vision, bifocal, and progressive eyeglasses. The lens recommendation program will give you a maximum of 3 options that are suitable for your prescription in the order of basic to advanced features. 

You can choose a package according to your budget. The first package is usually sufficient for your prescription. The lenses for advanced packages are usually thinner, lighter and have better cosmetic appearance. They are good options if you have higher budget.

Within each option, you can add Anti-reflective coating, sunglasses tints or upgrade to Polarized lenses or photochromic lenses. You will be presented with recommended lens packages after you enter your prescription. Please make sure you enter the year when you were born correctly on the prescription page because age is also a determining factor on lenses.

With our quality control system in place, you can rest assured that you will always get the best quality lenses for your prescription at unbeatable price.

Polarised sunglasses are fitted with polarised lenses. Polarised lenses provide improved outdoor vision with better contrast, clarity and because they reduce surface glare, they're ideal for activities like fishing, boating, driving and snowing sports. Most of our sunglasses are polarised sunglasses. You can also turn a eyeglasses with large frame into a polarised sunglasses by choosing polarised lens options in lens packages.

Yes. We have more than 30 different styles of prescription sunglasses for you to choose from. Apart from prescription sunglasses, all of our eyeglasses can be ordered with sunglass options such as tints, polarised or photochromic lenses.

The original sunglasses lenses will be replaced with the prescription lenses. Alternatively, you can choose a pair of eyeglasses and add prescription lenses. When choosing a lens package, remember to check the polarised lens option.

You may find that many of our eye glasses lens packages use ground lenses. All of the lens packages for bifocal/progressive lenses and prescription sunglasses use ground lenses.

In one word, ground lenses are custom-made lenses. Your lenses are specially made by a grinding procedure from a blank polymer that has a certain front curvature. Grinding removes the extra thickness from the lens to make the lens thinner. Lens grinding takes place after the lab receives your prescription. Orders with ground lenses usually take longer, some extra 2-3 days. Ground lenses are usually used when your prescription has a high power range. Sports eyewear and prescription sunglasses normally have higher front surface curvature and larger frame sizes and mostly can only be fitted with ground lenses.

Please note the following text is for your information only. You do not have to worry about the difference between different lens materials in order to choose your lenses. Our Lens recommendation program will present you with only the lens options that are suitable for your prescription.

about UV Protection
UV protection ensures your eyes don't suffer any sun-related damage, sun protection lenses screen out 100% of harmful UV radiation. You will be pleased to know that all of our lens products come with UV protection at no extra cost to you. All the lens materials listed below, apart from CR39, are manufactured with UV-protective coating. For CR39 lenses, we have added UV-protective coating at no additional cost to you.

plastic lens - CR39
Most lenses are plastic, the least expensive plastic used for eyeglass lenses is CR39 lenses. It is suitable for prescription with lower sphere. Although CR39 is not manufactured with UV-protective coating and scratch resistant coating, we add these coatings at no additional cost to you.

mid index plastic lens
These lenses not only provide you crystal clear vision, but also manufactured with scratch resistant coating. They are lighter, and thinner ( 37% thinner and 36% lighter than most CR39 plastic lenses), therefore they are more comfortable to wear than CR39 lenses if your prescription has higher power.

polycarbonate
Polycarbonate lenses are virtually shatterproof and are highly recommended for children and active adults. Polycarbonate lenses are lightweight (27% lighter than ordinary plastic lenses), safer, thinner and flatter. Plus, they have built-in UV protection. It is suited for rimless frames.

Polycarbonate lenses are not resistant to chemicals such as acetone or methylated spirit, which is commonly used in optical store to remove the marking on the lenses. Polycarbonate lenses are very difficult lenses to tint and are not available for sunglass tinting.

Trivex 1.53 lens (also known as Trilogy or Phoenix )
It is a new plastic lens material that is being used as a substitute for polycarbonate lenses. It is optically superior to polycarbonate in that it has less distortion than polycarbonate and it is lighter. Trivex 1.53 is resistant to chemicals such as acetone or methylated spirit. Like polycarbonate it provides 100% UV protection and it is extremely durable (ten times more impact resistant than ordinary CR39 lenses). Most importantly, it is a great substitute for polycarbonate lenses that need to be tinted, because it can be easily tinted but polycarbonate cannot.

1.74 super high index lens
This is the most upper market plastic lens. Suitable for very high minus prescription. They are manufactured with UV-protective coating, anti-reflective coating and scratch resistant coating. However, these lenses are not tintable and not available with polarizer.

Anti-reflective coating
Anti-reflective coating reduces the reflection on your glasses. This means people can see your eyes, not your lenses. You'll also see more clearly when driving at night, using a computer or during other harsh lighting conditions.

Scratch Resistant Coated Lenses
We provide scratch resistant coating on all lenses that we sell at no additional charge. We highly recommend a scratch-resistant coating on any lens you purchase in any occasion. Before you purchase lenses, check to see if scratch-resistant coating is included, or if it requires an additional fee.
