What strength (power/dioptre) should I choose?
There are a number of ways to determine the ideal strength reading glasses and reading sunglasses for you. Please note that in the interests of eye health we recommend regular eye tests and
consultation with an optician and these options are in no way a replacement for this.
Strength Calculator:
For an accurate guide, we recommend using our online strength calculator.
Simply by entering your latest glasses prescription, taken in the last two years, you will be able to find your ideal strength:
Calculate My Strength
Your Optician:
Your optician will be able to tell you what strength ready-to-wear reading glasses are most suitable for you either from your current glasses prescription or at the completion of an eye test.
Eye Chart:
Alternatively, as a good approximate guide to your reading strength please download and print out our eye chart which is in PDF format.
It is exactly A4 in size so must be printed onto A4 paper in it’s actual size with no page scaling, resizing or fitting selected.
The eye chart must be printed in order to ensure correct results as on-screen sizes vary between computers.

What size of frame should I choose?
All our reading glasses, blue light glasses, reading sunglasses and sunglasses can be sorted by frame width and full frame specifications,
including all dimensions, are listed on the item page and within the quick look feature. Frame width is measured as the distance from one side of the
frame to the other at the widest point. As a guide, a narrow frame width is considered to be anything up to 131mm, a
regular size from 132 to 138mm and a wide frame from 139mm and upwards.

Can you make up my glasses prescription?
+
-
Tiger Specs sells ready-to-wear reading glasses and reading sunglasses rather than prescription glasses and we are not an opticians so unfortunately we are unable
to make up your prescription.
Can I purchase your reading glasses and get prescription lenses put in them by you or an optician?
+
-
Unfortunately we cannot recommend or guarantee changing the lenses in our reading glasses since they are not designed for this purpose
and are manufactured with the same strength in both lenses. Additionally, since we are not an opticians we are
unable to make up any form of prescription.
Can I have different strengths in each lens?
+
-
We sell ready-to-wear reading glasses and reading sunglasses which are manufactured with the same strength in both lenses.
Therefore we are unfortunately unable to offer glasses featuring different strengths in each lens.
