1. How to Read Your Optical Prescription
An eyeglasses prescription can look complex. Here is a breakdown of the standard optometric abbreviations:
SPH (Sphere)
Indicates lens power needed to correct nearsightedness (-) or farsightedness (+). Measured in diopters.
CYL (Cylinder)
Represents lens power required to correct astigmatism. Left blank if no astigmatism is present.
AXIS
A number between 1 and 180 describing the orientation angle where astigmatism correction is aligned.
ADD (Addition)
Additional magnifying power required for the bottom section of multifocal/progressive lenses for reading.
2. Combating Digital Screen Eye Strain
In today's digital world, many suffer from Computer Vision Syndrome (dry eyes, headaches, fatigue). We recommend:
- The 20-20-20 Rule: Every 20 minutes, look at an object 20 feet away for at least 20 seconds to relax your focusing muscles.
- Blue-Light Filtering Lenses: Our customized blue-cut lens coatings selectively filter high-energy visible (HEV) blue light emitted by screens, helping maintain natural melatonin cycles and sleep.
- Ambient Lighting: Ensure your display is not brighter than your room's ambient light to prevent excess glare.
3. Eyewear Maintenance and Care
Keep your designer spectacles in pristine condition:
- Never Clean Dry: Small dust particles on a dry lens can scratch the anti-reflective coating. Always spray with optical lens cleaner first.
- Microfiber Only: Avoid tissues or shirts (which contain abrasive wood fibers). Always use the premium microfiber cloth provided with your frame.
- Two Hands: Always put on and remove your spectacles with both hands to prevent frame misalignment or stretching the hinges.
