Effects of Weight Loss on Contact Lens Fit

Contact lenses with 38% water content and 8.6mm base curve fit most of the people unless you are diagnosed with rare diseases or eye shapes. However, one must not forget that contact lenses are not one size fit all. Certain medications & life style do leave impact on contact lens tolerance & fitting-even weight loss.

Reducing too much of your body mass in a short period of time might make your body feel starved & de-hydrated. The fresh example is actor Domhnall Gleeson; who recently has lost too much weight for Anjelina Jolie’s Movie “Unbroken” that his contact lenses no longer fit him.

The story line of the film rotates around World War II; where his plane was gunned down over the Pacific Ocean & he was left all alone at the shore until he was rescued by Japanese sailors who kept him in prison for two years with little food for his survival.

Gleeson loses so much weight that his contact lenses no longer fit

To put a life in his character; actor took the job seriously & lost so much of his weight that he dropped contact lens size. O’Connel- the co-star said in a press conference; "Domhnall lost so much weight, even his eyeballs changed shape." 


"It's true," laughed director Angelina Jolie, noting the actors wore special lenses to make their eyes look bloodshot. "They fit when he was starting to lose weight and then by the time we got to the end of the raft section, they wouldn't go into his eyes. I think it was the dehydration." 

Strange fact; but yes looks like your cornea changes shape; as you lose weight. Even your eyes go skinny. Until eye professionals come forward to address this issue; we have no other option than assuming that reducing excessive weight specially in a short span may lay adverse effect on contact lensesfit.

Some Facts about Contact Lens Fitting


Contact lenses are not one-size-fit-all. Yet, there are some simple rules about contact lens fitting, as the average size of a human iris is 14mm. Contact lenses with a base curve of 8.6 mm fits most of the people whilst the water content of 38% keep circle lenses moist & your eyes hydrated.

Meeting your Eye Care Professional


  1. If you are wearing contact lenses for refractive index correction, you should meet your ophthalmologist for prescription needs such as astigmatism.
  2. People who wear contact lenses for personality enhancement should also meet eye care professional as there are several conditions that might affect contact lens tolerance such as the use of certain medication like birth control pills.  
  3. An eye care service provider will check your eyes to see if you are a successful candidate of contact lenses. Depending on your eye types; he will recommend you contact lenses that will fit your eyes whilst ensuring the maximum comfort.

Health of Cornea


  • One should take note of the corneal health. Tear film evaluation often describes how your corneas behave with contact lenses. Some people find it uncomfortable to wear contact lenses. This happens because of the quick degeneration of lipid that is actually the upper most layer of tear-film; serving as the barrier between foreign substances and your eyes.
  • In case of dry eyes syndrome; use FDA approved authentic eye drops. Not everyone needs eye drops. Circle lenses with water content 38% and above are comfortable to most of the eyes. However; people with sensitive eyes may opt for circle lenses above 50% water content or disposable circle lenses.
  • If you spend bigger portion of your day at working on computer then you are more likely to suffer from computer vision syndrome. Since working at computer alters the “blinking-rate” it indirectly affects the tear film production & aggravates the symptoms with contact lenses. This is how to manage contact lenses with computer vision syndrome.
