Misunderstandings to glasses

Misunderstanding 1: A teenager who is myopic would suffer from worse vision once he/she begin to wear glasses.

Actually this has no scientific basis. We realize the occurrence and development of myopia is the result of both gene and environment. While the myopia occurs on teenagers is mostly because of the environment. The long-time reading at a close distance, bad eating habit and reading habit would lead to worse vision. It is not because of wearing glasses that make eyesight worse. On the contrary, wearing right glasses would relieve eyes from fatigue. A pair of glasses together with good habits can make the myopia under control.

Misunderstanding 2: Wearing glasses would make you ugly.

This could be wrong. When selecting frames, professional salesman will provide you with customized service which means to recommend glasses that suit you, including suit your face shape, your hair color and style, your skin color etc. A pair of good glasses can not only correct your vision but also can make you look perfect.

Misunderstanding 3: It is okay to use others’ glasses.

It is definitely NOT okay! Every pair of glasses is customized according to prescription, which means there is almost no possibility for your condition just the same as that of others. Therefore, wearing other people’s glasses will not have the correction effect, it only make your vision worse.

Misunderstanding 4: The most expensive glasses are the best for kids

As the price of glasses varies with many factors such as type, style, material etc, it is difficult for parents to find out the best glasses for their kids. Therefore, they usually choose the most expensive glasses. In fact, the best glasses are the glasses that suit you best. For kids, it is better to choose kids glasses with full frame and polycarbonate material which is safe and light.

CR-39 began the change of optical lenses from glass to plastic materials. It is lighter weight, more impact resistant than glass lenses; thus, becoming a popular type of material used in single vision, bifocal, and multifocal or progressive lenses.

Material is low price and easy to manufacture. It is often preferred by individuals on a tight budget. However, because of its 1.50 index, customers with high prescription powers are recommended to use higher index lenses such as 1.56, PC, 1.67, or 1.74 lenses.

CR39 Lenses Features are:

Fragmentation: When plastic lens breaks, it breaks into larger fragments than their glass counterparts. Furthermore, the fragmented pieces are not as sharp as glass.
Fogging: CR39 lenses are less likely to fog-up than glass lenses because it responds more favorably to temperature changes.
Weight: Glass lenses are approximately 2X heavier than plastic lenses of similar size and shape. The lighter weight provides the wearer greater comfort.
Reflections: CR39 lenses have much lower internal reflection and surface glare than glass materials.
Tinting: CR39 lenses are great for tinting. Lenses can be tinted to virtually any color. Even lenses with variable thickness are able to be tinted evenly.

If you want thinner, lighter lenses, and have an milder prescription, then mid index lenses are the way to go. As prescription increases, the lenses become thicker. Thicker lenses increase internal reflections that reduce vision quality. Furthermore, thicker lenses add to the weight of each pair of glasses reducing comfort. Mid-Index lenses refract the light at a greater angle allowing the wearer to have a beautifully thin and light pair of glasses.

Mid Index Lenses Features are:

Fragmentation: When plastic lens breaks, it breaks into larger fragments than their glass counterparts. Furthermore, the fragmented pieces are not as sharp as glass.
Fogging: Mid Index lenses are less likely to fog-up than glass lenses because it responds more favorably to temperature changes.
Weight: Glass lenses are approximately 2X heavier than plastic lenses of similar size and shape. The lighter weight provides the wearer greater comfort.
Reflections: Mid Index lenses have much lower internal reflection and surface glare than glass materials.
Tinting: Mid index lenses are also tintable, so you can get that pair of sunglasses you’ve been eyeing for so long.

Polycarbonate lenses has a high index of refraction 1.59 and low density making PC lenses 20% thinner and 25% lighter than regular plastic lenses. Polycarbonate lenses are the most impact resistant lenses on the market. Therefore, it is the industry standard for safety goggles, and highly recommended for kids' lenses.

Polycarbonate Lenses Features are:

Impact Resistant: Polycarbonate material was originally made for uses on canopies covering fighter planes and then made its way into space on astronaut visors and space shuttle windshields. Today it is readily available to the public. It impact resistance makes the material extremely suitable for sports, industrial safety goggles, and children's eyewear.
Scratching: The reason for polycarbonate lenses' impact resistance is because of its "softness". Softer materials will flex instead of fragment when met with great force. However, the property allows lenses to be scratched easily. Therefore, every single one of our polycarbonate lenses is multi-coated with hard coating that forms a protective layer around the lenses allowing the lenses to be free from scratches while retaining its impact resistant qualities.
UV Protection: Polycarbonate lenses inherently carries UV protection properties that blocks nearly 100% of the UV rays from entering the back of the retina.

If you want thinner, lighter lenses, then high index lenses are the way to go. As prescription increases, the lenses become thicker. Thicker lenses increase internal reflections that reduce vision quality. Furthermore, thicker lenses add to the weight of each pair of glasses reducing comfort. Hi-Index lenses refract the light at a greater angle allowing the wearer to have a beautifully thin and light pair of glasses.

High Index Lenses Features are:

Fragmentation: When plastic lens breaks, it breaks into larger fragments than their glass counterparts. Furthermore, the fragmented pieces are not as sharp as glass.
Fogging: High Index lenses are less likely to fog-up than glass lenses because it responds more favorably to temperature changes.
Weight: Glass lenses are approximately 2X heavier than plastic lenses of similar size and shape. The lighter weight provides the wearer greater comfort.
Reflections: High Index lenses have much lower internal reflection and surface glare than glass materials.
Tinting: High index lenses are also tintable, so you can get that pair of sunglasses you've been eyeing for so long.
