Lenses for High Myopia – Thinner and Lighter
What lenses should people with high myopia choose? A guide to selecting the right index, coating, and frame for the thinnest and lightest lenses.

People with high myopia should optimize edge thickness, clarity, and coating durability when selecting lenses, as thick edges can cause glare and weight on the face. The overall strategy is usually high-index + medium small eye diameter + edge-covering frame + quality AR. Omitting any piece will reduce effectiveness — for example, only increasing the index while still choosing overly wide lenses.
Index Considerations
1.67 or 1.74 are commonly mentioned for high prescriptions; a medium index can be 1.60. CR-39/1.56 with larger sizes typically results in noticeably thick edges. The final decision depends on accuracy, frame shape, decentration, and budget.
The Role of Aspherical Design
Aspherical can reduce optical "bulging" when viewed from the side and slightly improve the perception of thinness. Not everyone is sensitive to the difference, but for high prescriptions, this is a worthwhile option to discuss with the optician.
Coating: AR is "relatively mandatory" for high prescriptions
Thick edges easily create reflections; good AR helps reduce glare when talking or driving at night. Combining scratch resistance and smudge resistance helps with cleaning and maintaining clarity. Skipping AR to save costs often leads to regret due to weight.
| Goal | Handling Approach |
|---|---|
| Edge Thin | 1.67/1.74 + medium lenses |
| Reduce Glare | Premium AR within budget |
| Edge Cover | Full rim |
After Receiving Glasses
Try them on for distance – intermediate – near; check for distortion on one side. If present, check axis and centering before suspecting prescription errors.
Multifocal Lenses for Presbyopia
High myopia + ADD requires progressive or two pairs of glasses; progressive lenses require lens height and an adjustment period. Do not self-estimate ADD at home.
Maintenance Habits
Clean with a microfiber cloth, spray with specialized solution; avoid rough shirts. Store hard cases when carrying.
Why Just "Switching to Thinner Lenses" Sometimes Isn't Enough?
If the frame is too wide or rimless, edges may still show or appear thick due to angle of view. Sometimes, it may be necessary to change the frame to cover edges and reduce effective diameter. The technician can simulate estimated thickness before you finalize.
Night Driving and High Prescriptions
High prescriptions can easily encounter halos around lights if the coating is poor or the eyes are dry. Good AR helps but does not replace tears and clean windshields. If unusual symptoms occur, get an examination to rule out high astigmatism or other pathologies.
High Myopia + Astigmatism: Axis and Centering Are Even More Important
High astigmatism is sensitive to axis and centering. Do not self-correct prescriptions from old glasses if it has been several years; even small deviations can cause blurriness with elliptical shapes.
Budget: Allocate Between Lenses and Frames
Some customers spend too much on designer frames but cut back on coatings — with high prescriptions, this is often a mistake. Prioritize index + AR within budget, and choose stable frames before chasing trends.
| Priority | Suggestions |
|---|---|
| 1 | Accurate measurements, clear prescriptions |
| 2 | Index + AR |
| 3 | Edge-covering frames |
High Myopia and Dual Screen Work
Two screens at different distances may require wear height and optimal intermediate point; vertical misalignment can easily cause neck strain. Discuss screen height and average distance with the optician to consider office lenses or adjust near vision if appropriate.
Psychology and Aesthetics: Living with High Prescriptions
Many people are hesitant about thick glasses; investing in the right combo helps boost confidence in communication. Do not compare online photos with different prescriptions — each prescription and frame yields different visual results.
Follow-Up and Prescription Updates
High myopia can progress or stabilize depending on the individual; follow-ups help avoid wearing outdated glasses that cause excessive pupil compensation. When changing prescriptions, reconsider the index — sometimes increasing one index level when the prescription rises will maintain aesthetics better than sticking with 1.56.
Metal Frames vs Thick Plastic
Thin metal frames may reveal edges more than acetate frames with edge-covering — consider lens height and diameter when choosing the shape — choose frames.
Rimless Glasses for High Myopia
Rimless glasses are aesthetic but edges are fully exposed — usually only suitable when combining index + small diameter + precise edge grinding — ask the technician to simulate thickness beforehand.
Multifocal and Thick Edges
The distance viewing area of progressive lenses still has edges; high myopia + multifocal = requires corridor and sufficiently high frames — multifocal, two pairs.
One Eye More Myopic (anisometropia)
Images from two different sized eyes can cause discomfort; need to balance index / thickness — do not self omit one eye on the prescription if the technician has not evaluated — measure accurately.
Insurance / Support for Thin Lens Costs
Some companies have employee packages — ask HR; still prioritize accurate prescriptions over buying the most expensive — pricing table.
1.74 Sometimes… Not Necessary
The highest index is expensive and sometimes the coloration differs slightly from 1.67; should only upgrade to 1.74 when the edges are still thick after optimizing diameter + frame — ask the technician to simulate before paying extra — Tokai.
Contact for measurement and consultation, see products, read articles. Lenses for high myopia are a trio: index + coating + proper fitting — missing one factor significantly reduces effectiveness.
