Tinted Lenses for Visual Stress
Visual stress describes a range of visual discomfort and perceptual symptoms that some individuals experience when viewing text. Symptoms may include visual distortion, movement or instability of print, glare, difficulty maintaining visual attention, headaches and increased visual fatigue during reading.
For individuals who experience these symptoms, tinted spectacle lenses may provide a personalised approach to improving visual comfort. The selected tint is tailored to the individual rather than using a standard colour, with the aim of reducing visual discomfort associated with specific visual environments or tasks.
Once the preferred colour has been established, it can be incorporated into Tinted Lenses, providing a consistent, personalised tint within the patient’s spectacles.
The result is a clinically informed, individualised approach to tinted spectacle lenses, designed to optimise visual comfort for patients who experience symptoms associated with visual stress.
The recommended Colorimetry assessment process follows a 3 stage process:
1. Full Eye Examination
It is essential that everyone who struggles to read or believes they may suffer from symptoms of Visual Stress, first undergoes a full eye examination. This is important to rule out any ocular problems. The eye examination is available free of charge for all school aged children, students who are studying full time up to the age of 19 and any adults who are entitled to an NHS sight test. Colorimetry Assessment charges apply separately.
2. Colorimetry Assessment
Following the eye examination, if appropriate, we can carry out a colorimetry assessment using the Intuitive Colorimeter under the direction of a Dispensing Optician. This allows us to carefully assess different colours and determine the most comfortable and beneficial tint for your individual needs.
The colour will be specific to each individual, with the colour, saturation and intensity carefully adjusted to find the most suitable tint. Where appropriate, we can supply glasses with your prescribed precision tint, providing a convenient option for board work, writing and computer use.
3. Your Precision-Tinted Glasses
Once your individual tint has been established, your precision-tinted glasses can be made to your prescription and personal requirements. When your glasses are ready, we will invite you back to collect them and make sure they are comfortable and fitted correctly.
We will also provide guidance on using your new glasses and answer any questions you may have, so you can feel confident wearing them for your everyday visual needs, including reading, writing, computer work and viewing the board.
