Universal Eyeglasses

Adaptive eyeglasses change lens power with the turn of a dial. Users can quickly and easily determine their own lens power for near or distance vision. They then can fix the power in a simple process that takes only minutes.


Adaptive eyeglasses use adjustable lens technology. Adlens eyeglasses contain fluid-filled lenses that change shape and therefore focus depending on the amount of fluid inside the lens. The lenses are protected by polycarbonate covers and are both durable and easy to clean.


Turning the adjuster knob pumps fluid into or out of the lens structure, thereby changing the lens power. Once at the desired power, the user simply seals the lenses and removes the adjusters.


Adaptive eyeglasses work for distance, reading, or for computer and mobile phone distances.

Forget those old red and blue 3D glasses. ChromaDepth 3D glasses by Chromatek are clear as water and give you an amazing 3D view of any color image. You see each color at different depths. On a black background, red will appear closest, blue farthest, and the other colors will fall in-between according to their place in the rainbow (red, orange, yellow, green, blue).

The Good and the Bad

Negative ions are good for us. You might want to avoid positive ion generators and ozone generators. Whenever I need a new air cleaner (with negative ion generator), I buy it from A plain old air cleaner is better than nothing, but one that produces negative ions makes the air in a room fresher and easier to breathe. It also helps to brighten my mood.

Never litter. If you can't find a trash can, take it home and throw it away there.

Hydrofracking is bad for you, your family, your friends, and the environment.

Some people appear to have a mental illness because they have a vitamin B deficiency. I take B-Right.

Unfermented soy is bad! “When she stopped eating soy, the mental problems went away.”
