Power Adjustable Glasses
From Reading To Driving
One Pair Does It All

These glasses work by using either sliding lenses that change the lens power or fluid-filled lenses where the prescription is adjusted by increasing or decreasing the amount of fluid in the lenses. This adjustment alters the curvature of the lens, thus changing the focal length and allowing for clearer vision at different distances.

Vi-Shift Glasses are particularly beneficial for individuals with presbyopia, a condition common in people over 40, where the eye's lens loses elasticity, making it difficult to focus on close objects. They are also useful for those who have varying degrees of vision throughout the day or for those who do not have access to an optometrist for a regular prescription update.

While Vi-Shift Glasses can be a convenient alternative for specific tasks or temporary use, they may not completely replace prescription glasses tailored to an individual's specific vision needs, especially for those with astigmatism or high prescription requirements.

The method of adjustment varies by the design of the glasses. Generally, there will be dials, sliders, or knobs on the frames that you can move to adjust the focus until you achieve clear vision. It's important to start with the glasses at the lowest setting and gradually increase until you reach the desired clarity.

Vi-Shift Glasses are designed with durability in mind, but like all eyewear, their lifespan depends on how well they are cared for. It's important to follow the manufacturer's instructions for care and handling to ensure they last as long as possible.

To care for your Vi-Shift Glasses, clean them regularly with a soft, dry cloth. Avoid using harsh chemicals or abrasives. Store them in a protective case when not in use to prevent scratches and damage. Do not expose them to extreme temperatures or moisture.

Vi-Shift Glasses may not be suitable for driving, especially if they do not correct astigmatism or provide the level of precision required for safe driving. It's best to consult with an optometrist to determine if your Vi-Shift Glasses meet the legal requirements for driving in your area.

Yes, Vi-Shift Glasses may not provide as precise a correction as custom prescription glasses, especially for individuals with astigmatism or those requiring bifocals or multifocals. They are best used as a supplementary pair of glasses rather than a complete replacement.

Vi-Shift Glasses can be purchased online, at some optometrists' offices, or at retailers specializing in eyewear. It's important to purchase from a reputable source to ensure the quality and effectiveness of the glasses.
