Frequently Asked Questions
Can you repair glasses that weren't originally purchased at Mountain West Optical?
Most frame styles can be repaired regardless of where they were originally purchased. In-house technicians handle bent frames, loose hinges, broken nose pieces, and popped lenses the same day in most cases. This eliminates shipping delays and gets you back to work, school, or daily activities without waiting weeks for manufacturer repairs.How does having an in-house optical lab affect turnaround time for prescription glasses?
Lenses are cut, edged, polished, and fitted on-site in Twin Falls, which allows same-day or next-day completion for many single-vision, bifocal, and progressive prescriptions. Online retailers and big box chains typically send frames to off-site labs, adding 7-14 days. The in-house lab also enables immediate quality control adjustments without reshipping.What types of glasses repairs can be done the same day in Twin Falls?
Same-day repairs typically include bent frame realignment, hinge tightening or replacement, broken nose piece replacement, popped lens reinsertion, and frame adjustments. Walk-ins are accepted, and most repairs are completed while you wait. This avoids the cost of replacing quality eyewear entirely when minor damage occurs.Can you add prescription lenses to frames I already own?
Existing frames can be fitted with new prescription lenses as long as the frame is structurally sound and compatible with the lens thickness required by your prescription. This works well for updating prescriptions, converting regular glasses into sunglasses, or replacing scratched lenses. Bring the frame in for evaluation and custom lens fitting.What's the difference between CR-39, polycarbonate, and high-index lenses?
CR-39 is standard plastic offering optical clarity at lower cost but thicker profile. Polycarbonate is impact-resistant and lighter, ideal for children and safety eyewear. High-index lenses are thinner and lighter for strong prescriptions, reducing edge thickness and weight. Lens choice depends on prescription strength, lifestyle, and budget.How does custom lens tinting work for prescription sunglasses?
Lenses are tinted in-house with custom colors, densities, and finishes including gradient tints, mirrored coatings, and polarization. Tinting can be added to most existing prescription frames without replacing the entire pair. Popular options for southern Idaho include gray and brown tints for driving and fishing, and darker tints for skiing or construction work.What makes ANSI Z87.1 compliant safety eyewear different from regular prescription glasses?
ANSI Z87.1 eyewear uses impact-resistant lens materials and reinforced frames tested to withstand high-velocity projectiles and workplace hazards. Regular prescription glasses lack these protections and can shatter under impact. Safety eyewear is required in construction, agriculture, and manufacturing environments and can be custom fabricated with prescriptions through the in-house lab.Can you convert my regular prescription glasses into prescription sunglasses?
Existing frames can be fitted with custom-tinted prescription lenses, polarized lenses, or mirrored coatings without purchasing new eyewear. The in-house lab handles lens replacement with your current prescription, allowing you to keep favorite frames while adding sun protection. Gradient tints and transitions lenses are also available for most frame styles.Why do some prescriptions require high-index lenses instead of standard plastic?
Strong prescriptions create thick, heavy lens edges with standard plastic materials. High-index lenses bend light more efficiently, reducing thickness and weight by 20-50% depending on prescription strength. This improves comfort, appearance, and frame compatibility for prescriptions above +/- 3.00 diopters or those with significant astigmatism.What happens during a comprehensive eye exam at Mountain West Optical?
Exams include vision accuracy testing, eye health evaluation using advanced imaging, and screenings for glaucoma and retina conditions. You'll receive personalized recommendations for glasses, contacts, specialty lenses, or surgical referrals based on findings. The exam combines diagnostic assessment with practical guidance on correcting vision problems or managing eye health conditions.How do polarized lenses help with glare while driving or fishing in southern Idaho?
Polarized lenses block horizontal light waves that create glare from reflective surfaces like water, snow, windshields, and pavement. This improves visibility during fishing by revealing underwater structure, reduces eye strain during long drives, and enhances contrast for outdoor activities. Polarization can be added to prescription sunglasses fabricated in the Twin Falls lab.What frame and lens features work best for children's everyday eyewear?
Impact-resistant polycarbonate lenses and flexible, durable frames withstand drops, sports, and daily wear better than standard materials. Scratch-resistant coatings extend lens life, and proper fittings prevent slipping during activities. Frames should fit securely without pinching, and prescription accuracy matters more as vision develops. Quick repairs and adjustments keep kids functional without extended downtime.
