If you’ve had a close look into your pet kitten’s eyes or watched a couple of animal documentaries in your time, you have probably noticed that there are a variety of different pupil shapes across the animal kingdom. The pupil is the black centre of the eye and in humans is round. This is the part of the eye that allows light through to the retina and controls the level of the light entering the eye.
Everyone says that the eyes are the window to the soul… but how true is that? Is it possible for people to know what you’re thinking based on your eye movements, in the same way that body language can provide indications of your thoughts and feelings?
Cats’ eyes glow in the dark because they reflect light. This is because they are nocturnal animals, meaning they hunt in the dark, and the phenomenon of their reflective eyes (called tapetum lucidum) boosts their night vision significantly.
Blue light blocking glasses are special glasses which are supposed to filter out blue light, purportedly protecting your eyes and preventing the onset of certain eye conditions such as age-related macular degeneration and other forms of retinal damage. But how much of this is true?
Eggs are actually one of our top 10 foods for boosting your eye health! Eggs are rich in lutein and zeaxanthin, which are vitamins proven to protect your eyes from ultraviolet damage. Exposure to UV rays can increase your risk factor for developing cataracts and macular degeneration, both of which can threaten your vision permanently.
The iris (the coloured part of your eye) is usually just made up of one colour, such as brown, green, blue or hazel, but some people experience multiple shades at once – whether that’s different distinct colours within a single iris, or each iris having its own colour entirely.
In February of this year, we treated our lovely patient Georgie with LASIK laser eye surgery. Georgie is a former reality TV star but now works as an Instagram influencer. She struggled with glasses and contact lenses for several years and, with her job involving modelling, travelling and a generally busy lifestyle, it was quite often a nuisance.
You’re probably reading the title of this article and thinking, “what?! How?!” We’ve all heard of sunburned skin and, if you’re really unlucky, you might have experienced a sunburned scalp. But, unfortunately, there’s another body part to add to the list of places which can get sunburned – and it’s your eyes.
Back in 2017, we treated our lovely patient, Collette, in our Optimax Liverpool clinic. She had needed glasses for practically her whole life, and finally took the plunge and opted for lens surgery once she reached her 40s. Most people start to need reading glasses around this age, so Collette opted for multifocal lenses in both eyes to ensure that she could live life without any type of glasses or contact lenses.
As you get older, the proteins in your eye clump together and, over the years, this slowly clouds the natural lens in your eye. Cataract surgery is performed more than 18 million times globally each year. By the age of 80, over half over people will have had a cataract as it is simply a natural part of the ageing process.
