Are Prescription Glasses Free?
No prescription glasses are not completely free. But in the UK the price of glasses are subsidised by the state for all children under 16.
For adults it depends on your employment status and financial means as to whether you will may obtain financial assistance towards the cost of prescription glasses.
Some opticians do provide a limited range of prescription glasses with no extra cost added on top of the assistance given.
So technically you could obtain them for free. But the costs are paid for by the state.

How are prescription glasses made?
Glasses or spectacle frames are supplied by factories all over the world to wholesalers and multiple Optician retailers, who store them ready for customers to try on.
Glasses are supplied with plane dummy lenses in the frame usually with the brand logo painted onto the lens. This keeps the lens shape intact during shipping, storage and provides a good aesthetic look when trying them on.
Prescription lenses are supplied by lens manufacturers and stored in spectacle lens workshops either onsite within opticians, or offsite at specialist factories.
The lens is usually in a semi-finished form, meaning the front surface of the lens is polished with a specific curve. Then the lab polishes ‘surfaces’ the back surface to the specified power.
Then the glasses frame is digitally scanned via the inner bevel that holds the lens in place. The lens is then cut and edged automatically by machine and fitted by the technician securely into the frame.

Will Glasses Help Eyestrain?
Yes. If caused by a continuous blurred image, over accommodation (focusing) or a misalignment of the eyes.
Will My Prescription Glasses Be Thick?
Prescription glass lens thickness is determined by the powers found prescribed by the Optometrist or digital device like the Eye Que.
The final thickness of the lens is governed by the refractive value of the lens material known as refractive index and the curvature required to focus the light to the value of the prescription.
The higher the refractive value of the lens material the flatter the curve needed, therefore reducing the overall thickness of the material.
