Aloha Eyewear Tek Spex 3001 Women's Progressive No-Line Rimless Computer Reading Glasses with Blue Light Blocking Lens
Thousands of people have discovered the power and freedom of our Tek Spex progressive no-line readers, and now there's a Tek Spex specifically engineered for people who love to spend time online! Tek Spex 3001 feature a coating that is perfect for filtering out high-frequency blue light from your vision Ñ essential for those who require or enjoy extended sessions of "screen time" on their computers, televisions, smart phones, or tablets. Blue light can be harmful when exposed to your eyes for long stretches, increasing the risk of headaches (including migraines), visual distortion, visual stress and fatigue, and wakefulness. That last one is especially important: at night it's highly recommended you allow your eyes some down-time in preparation for a restful night's sleep. And millions of people read on their devices every night to slow down their brains right before bed. However, if you don't have a way to block the high-frequency blue light from entering your eyes, it will often have the opposite effect, increasing the time it takes to fall asleep and shaving precious minutes or even hours from your sleep schedule! Tek Spex 3001 are custom engineered to block a large spectrum of blue light from your eyes increasing comfort, stamina, and restfulness whenever you read from your devices. Our progressives are superior to conventional progressive lenses because Tek Spex lenses are made using the latest Digital-Ray-Path technology. Digital progressives are extremely easy to get used to: they do not have as much distortion (also known as aberration) on the sides of the lens the way conventional progressives do, resulting in a much clearer field of view. They deliver freedom to see clearly in every direction, which only the finest progressive no-line optics can provide. See the difference for yourself!

The dimensions of each model are listed in the description/bullet points, both in mm and in inches. In general use the following guide when deciding fit. (This may not apply to sports styles which "wrap around")
Narrow (small faces) = 40-48 lens width
Medium (average) = 49-54mm lend Width
Wide (large) = 55-58mm
For RX-able Models
the "optical standard" measurement is given. This number is also inscribed on the inner temples of the glasses. There are three sets of numbers:
1. The first number listed gives the width of each of the lenses.
2. The second is the bridge, which is the distance between the lenses.
3. The third is the length of the temple arms.
Progressive glasses also take into account PD, or "pupillary distance" which is the distance between the left and right pupils. The average distance for most people is 63mm. Our progressives are set to this average. If your PD is + or - 3mm or more these glasses may not suit you. You can check your pupillary distance easily by looking in a mirror using the folding method:
