METAL READING GLASSES BROAD LENS (sheheri)

Off-the-shelf reading glasses for presbyopia (age-related farsightedness). Available in mixed diopter strengths (typically +1.0 to +3.5 in the pack or by individual unit).

Benefits:
- Pre-set magnification (positive diopter) — no prescription needed
- Sturdy metal frame — durable for everyday wear
- Lenses ground to the marked diopter (e.g., +1.50, +2.00, +2.50)
- Suitable for short reading and close-work tasks
- Affordable alternative to prescription glasses for users with simple presbyopia

- Reading books, newspapers, phone screens, food labels
- Sewing, needlework, model-building, fine handwork
- Cooking (reading recipes, measurements)
- Simple presbyopia (age-related need for stronger near-vision focus, typically starting in mid-40s)
- Backup pair for travel, the kitchen, or the bedside

How to Use:
Pick a diopter strength: try +1.0 to +1.5 if you're 40-50 and just noticing trouble; +1.75 to +2.50 for typical 50-65; +2.50 to +3.50 if older or for very fine work. The right strength is the one that lets you read at comfortable distance (about 35-40 cm from the page) without strain. If both eyes need different prescriptions (common), see an optician for prescription lenses instead.

Precautions:
- Don't use as a substitute for a prescription eye exam — see an optician at least every 2 years
- Off-the-shelf glasses don't correct astigmatism, prescription differences between eyes, or pre-existing eye disease
- Stop wearing if you experience headaches, eye strain, or distorted vision
- Sudden vision changes need a doctor's evaluation, not stronger reading glasses
- Children should not use these — they need professional refraction
- Keep clean with a microfibre cloth; avoid harsh chemicals on plastic frames

Q&A:
Q: Reading glasses or progressive lenses — which do I need?
A: Reading glasses are for close-work ONLY. If you need to switch between reading and seeing across the room, prescription progressives or bifocals are far more practical. Off-the-shelf reading glasses work for someone whose distance vision is already perfect.

Q: Why are these so much cheaper than prescription glasses?
A: They're mass-produced with the same diopter in both lenses and no astigmatism correction. Prescription glasses are custom-ground for your specific eye measurements. For SIMPLE age-related close-work blur, off-the-shelf works fine; for any complexity (different prescriptions per eye, astigmatism), get prescription.

Q: When do I need to upgrade strength?
A: Most users go up by +0.25 to +0.50 every 2-3 years through the late 40s to mid 60s. If you're holding the page further away to read clearly, that's a sign your current strength is too weak.
